Title sequence in AE and C4d

10 Feb
  1. Launch AE and create a new composition with 1080p 25 fps.
  2. Import a background image or image sequence or movie file to a layer. Make this personal and relevant to your project.
  3. Create a new Cinema 4d layer from Layer -> New -> Maxon Cinema4d File.
  4. Save the new Cinema 4d file.
  5. Cinema Lite automatically opens.
  6. Create a text spline. Write down the title of your project. Choose the font to your liking. Texture to the style of your project. You can create more lively text by using a different texture shade for the beveled edges of your text. C4d creates it’s own selection tags for extruded objects. They are named C1 and C2 for caps and R1 and R2 for bevelled/rounded edges.
  7. Extrude text. Select cap and fillet type to your liking.
  8. Save the C4d file and jump back to AE. Note that C4d file is updating in AE.
  9. Export a frame from AE to use in C4d as a reference. Select Composition -> Save Frame As -> Photoshop Layers.
  10. Save your AE file.
  11. Bring the background image to C4d and add it as a material to Background object. Background object will not render in Cineware.
  12. Create a new camera for render. Use the background image as a reference and move the camera to match the perspective of the image.
  13. Light the scene so that it matches the background it is supposed to be composited to.
  14. Animate the text with using MoGraph.
    1. Select Mograph -> Fracture and drag extruded text as an child of the Fracture object.
    2. Change the fracture objects Mode in attribute editor to Explode segments and connect.
    3. In order for the Fracture object to work, it needs to have an effector applied to it. Fracture object selected, go to Mograph -> Effector -> plain.
    4. Go to Plain effector and click on the Falloff tab. Change the falloff from infinite to linear. A wireframe box appears in the viewport and that allows you to control the fracturing.
    5. Click on the checkbox for invert.
    6. Enter -90 degrees for the heading rotation R.H
    7. Click and drag the yellow arrow inside the wireframe box left and right to see how the linear falloff affects the movement of the letters.
    8. Animate the position so that the letters animate down to their position. Animation should last 110 frames. Check the animation.
    9. When animation is ok, change the values of the plane effectors parameters as follows:
      1. y-position -225 cm
      2. z-position -900 cm
      3. Pitch (R.P) 180 degrees.
      4. Now the text should fly into the scene
  15. Change the render settings as needed, use ambient occlusion and make sure the anti-aliasing is set to best.
  16. Save the project and go back to AE.

  • Morphing splines to each other. These splines can then be animated with different methods, e.g. by animating the surface generator sweep.

Pose Morph

  • Morphing different shapes of one mesh into another shape of that mesh.

Path Animation

  • You can attach an object to a spline to make it follow the spline by using a align to spline tag. Spline will become parametric, so the animation is done by keyframing its position percentage on the spline. Remember to click on tangential option on the attributes.

Deformer objects

29 Jan

Deformers are used to deform the geometry or to perform some deforming animation tasks. They can be used on primitive objects, generator objects, polygon objects and splines. They work on its parent objects or its piers. Multiple deformers can be assigned to objects, but note that in that case the order of deformers makes the difference on the end result. Make sure there are enough points on the object deformed.

Muokkaavat toiminnot muokkaavat objektin geometriaa tai niitä voidaan käyttää animaation tekemiseen. Niillä voidaan muokata primitiiviobjekteja, luomisobjekteja, polygoneja tai käyriä. Ne vaikuttavat hierarkiassa niitä ylempänä oleviin objekteihin sekä samalla tasolla samassa hierarkiaketjussa oleviin objekteihin. Muokkaimia voidaan käyttää useampia samalle objektille, jolloin muokkainten esiintymisjärjestyksellä on merkitystä. Tärkeää on se, että objektilla on tarpeeksi muokattavia pisteitä sulavan lopputuloksen aikaansaamiseksi.

What is MoGraph?

MoGraph is a procedural modeling and animation module within CINEMA 4D. What it really is though, is a collection of objects, and at the heart of those objects is something called the Cloner object. What MoGraph excels at is making copies and then repeating those copies and manipulating those copies.

What can be done using MoGraph?

Inspect the different ways to use the Mograph module in c4d by looking at the tutorials and videos made by using the tools in Mograph module. Choose a technique, which you think is interesting/looks cool and present the idea for the class by sending a link to the video/tutorial as a comment to this post.

The Art of Rendering

16 Feb

Rendering is the process in which the 3D scene is calculated and rendered to create a 2D image(s). The computer produces a flat picture of the view through the camera for a still image of each sequential frame of the movie. It takes into account lighting, reflections, shadows, and all the other influences of the environment. The process is often a delicate balance between the level of quality you must have and the time it takes to render the project.

General

Render Engine

Full Render – will use C4D or the Advanced Render engine to output a high quality render

Software Preview – the scene will render as it looks unrendered in the viewport

Hardware preview – the scene renders as it looks unrendered in OpenGL display mode

CineMan – allows access to other render engines such as Render Man

Output

Resolution

This is where you set the size of your still frames in pixels. Select the image size needed accordingly to your final output medium. (HDTV 1080 24- 1920×1080 in our case) In the viewport you can set the Render Safe borders to be on or off, so that you can see exactly which areas of your work will show up in your final render.

Check that the Frame Rate is set to 24 or 25 frames per second and that the Frame Range is set to Manual. Then you can specify the Frame range start (From) and end (To) frame yourself.

Save

First of all, if you want to render your frames and store them, the save-tab needs to be checked on. Then you can specify the path in which folder you want your frames to render.

When rendering an animation, it is important to create a folder for the frames. Otherwise you end up doing a lot of housekeeping later on with all the frames that get splattered all around your desktop. Save your frames as preferred file format and select the naming option filename.0000.tiff.

Alpha Channel

Check on Alpha box if the image needs to store an Alpha channel for a further compositing work. The entire alpha channel is masked if you use a Sky, Floor, Foreground or Background object in your scene. Do not use any of these objects if you need the alpha channel.

Dithering is a process that adds a random pattern to colors to prevent color banding. Although dithering enhances the image quality, it also increases file size. For web graphics in particular, you may want to disable dithering to reduce image file size.

Compositing Project File

The Compositing Project File option ensures that all Multi-Pass renderings can be consolidated easily and combined with the correct layer copy mode in the project file, without having to import all assets and channels individually. Additionally enabling the Include 3D Data option will pass this information on to the target application, ensuring that cameras, lights and layers are included. Of course this option can be left disabled, if desired. In our example, our scene will be subsequently edited in After Effects CS4. Therefore, select After Effects as the Target Application.

Multi-Pass

This option is a powerful tool if you are compositing the rendered frames in After Effects later on. Multi-Pass allows you to render different artistic possibilities at one time, and then have them as separate layers in the compositing program. You can specify, which elements to include to your multipass render from the Multi-Pass menu at the top of the Render Settings window. (if you’re only interested in the multipass image, you can disable the Regular Image in the Save options) H.264 files do not support Multi-Pass.

When using multi-pass in rendering it is best to use a linear workflow to ensure the colours are shown correctly. Make sure the linear workflow continues in the compositing software you use. Here is how it works.

Tutorial on lightening up your renders.

Anti-Aliasing

When antialiasing is off, the corners of the pixels on the edges of the polygons can appear jagged. When you are test rendering, the setting None is fine and will save time. In the final render, set the quality to be Best.

Min Level defines the minimum number of sub-pixels that will always be rendered. The default value of 1.1 will suffice for most cases. If, however, artefacting should occur in very detailed regions, e.g. shadow elements get swallowed, higher values should be used.
Max Level is the sub-pixel dispersion that is applied to critical regions (mostly high-contrast regions, i.e. color edges or object edges behind transparencies). This value can, for example, be increased when rendering glass to ensure the rendering of finer details. In an average scene with a Threshold (Color) value of 10%, about 40% of all pixels will be affected, whereas a Threshold value of 5% will result in 90% of all pixels being affected. A value of 0% will cause all pixels of a rendered image to be antialiased – including superfluous regions. This can significally slow down your render time.

Render Tag

Note the Render tag in conjunction with the above.
This tag can be used to define antialiasing settings on object level. In the Edit Render Settings menu, set Antialiasing to Best and the Min/Max Level values each to 1×1. This reflects the least amount of antialiasing for the entire scene (i.e. none). You can, however, use Render tags to define the amount of antialiasing each object should have individually. This lets you, for example, apply a high level of antialiasing to prominent foreground objects and progressively less to objects that lie correspondingly further in the background.

In the Filter pull-down menu, choose the Animation filter for the movie project, which will result in smoother edge, which is less prone for flickering. (Allows the Softness to be controlled by a value  for a customizable effect)

Options

Ray Treshold – Only a small precentage of the processed rays feed into the overall color and brightness of the final render. Any ray that falls under the precentage will be left out and the render times can be greatly reduced.

Ray Depth – Determines how many transparent objects, including those made transparent by the use of Alpha Channels, can be penetrated by the renderer. A low value can speed up the render. Too low value can result in transparent objects rendering black and there is a need to raise the value.

Reflection Depth – Determines the shadow depth calculated for the visible shadow rays. A value of 15 is usually suitable unless you have many transparent, reflective or refractive elements in your scene. Then you need higher value.

LOD (Level Of Detail) – can help reducing render time by lowering the subdivision level at which objects will be rendered. Can be lowered per object through using the display tag.

Bucket sequence and size – If you have a very powerfull machine, you may increase the rendering time by raising the bucket size.

General lighting tips

16 Feb

Choosing an Appropriate Lighting

It is important to make conscious decisions about emotions and design ahead of time , so that lighting is chosen and edited to enhance the overall goals for the scene. Here’s a partial checklist:

  1. What is the mood of the scene and what overall brightness (intensity slider) is appropriate? Which type of light will best fit the scene’s sense of time and place?
  2. How do multiple lights in a multiple light arrangement relate to each other in intensity and contrast? How will this ratio affect modelling and shadows?
  3. Should light come from one source for a hard edged, dramatic look or have multiple points of origin for a softer, more diffused feel?
  4. How rapidly will the intensity of the light fall off?
  5. Will light travel in one direction and stop or bounce from surface to surface?
  6. What colour is the light? Should the colour convey a specific mood? Can the warmth or coolness of lights be used to articulate space or establish time of the day?
  7. What kind of shadows are appropriate for the mood of the scene?
  8. Will the light be animated to move, flicker, surge, or changein intensity or colour over time? Will the light have shadow patterns moving through it?
  9. Is the light visible? Does it honor the mass of objects in its path? Is it clean or is it filled with dust?

General Tips for Lighting

  1. Name lights by the function they are performing in the scene. Names like 70 percent Main, 40 percent Fill, Backlight etc. say so much more than light1 and light2.
  2. Set up lighting in regard to the active camera.
  3. Shift-click to select multiple lights for simultaneous editing.
  4. Use Gouraud shading for feedback on how the lights are affecting the scene.
  5. Use the gray visibility switches to turn the lights on one at the time to see the effect each light is having on the model.
  6. Model for lighting. Sharp corners have no surface to catch light. Create fillets, roundings and bevels on your models to show off the highlights.
  7. If the scene calls for multiple lights, check the No Illumination check box for most of them so the dominant light still comes from one direction. Not only will too many radiating lights quickly overexpose the scene, but light from too many directions can be visually chaotic. Set up a strong basic structure of light and shadow, and then add puffs of visible colour that add interest but contribute no illumination to the scene. Think of it as painting with light.
  8. Turn off textures temporarily to see lighting effects more accurately.

3-POINT-LIGHTING-EXPLAINED

3-POINT LIGHTING IN C4D

1. KEY light – päävalo

  • Main light source, the brightest light source in the environment.
  • Defines the main direction of the light in the scene.
  • When designing the lighting setup, the most important aspect to consider is the angle in which the light illuminates the subject. The key light is most often situated diagonally up and to the side of the subject, about 15-45 degrees to the side and 15-45 degrees up from the camera position. There is an exception in the situation that subject’s profile is lit. Then the light source needs to be situated that way that it illuminates the whole subject.
  • If the key light is too close to the subject, the illusion of the depth suffers. When the light is too far away, the subject might not be fully illuminated.
  • When lighting the face, consider the nose as a kind of solar watch, where the shadow of the nose acts as an indicator of the light. Normally the shadow of the nose points to the direction of the mouth. This is how we are used to seeing people.
    • Light too far to the side: nose shadow is pointing more towards the cheek and it looks disturbing.
    • Light too low: the most disturbing light position, which results in ghost like, greepy result. Can be used as an effect.
    • Light too far up: The resulting shadows block the eyes and the subject will look like a racoon. Not very pleasing.
    • Light too far back: dramatic effect, where the subject will look more like a silhouette.
  • Tilan pääasiallinen valonlähde, ympäristön kirkkain valo.
  • Määrittelee valaisun pääasiallisen suunnan.
  • Kohteen valaisussa tärkein asia on päättää, missä kulmassa päävalo saavuttaa kohteen. Päävalo sijoitetaan useimmiten yläviistoon, hieman kohteesta sivulle, n. 15-45 astetta sivuun ja 15-45 astetta ylös kamerasta. Poikkeuksena tilanne, jossa kohdetta kuvataan profiilissa, jolloin valoa käännetään niin, että se valaisee kohteen kokonaan.
  • Jos päävalo on liian lähellä kohdetta, kohteen muoto menettää syvyyttä. Jos taas valo on liian kaukana, saattaa kohde jäädä osittain valoittamatta.
  • Jos valaiset kasvoja, voit ajatella nenää eräänlaisena aurinkokellona. Nenän varjo osoittaa normaalitilanteessa suuta kohti valon tullessa yläsuunnasta. Näin olemme tottuneet näkemään ihmisiä.
    • Valo tulee liikaa sivulta: Kun päävalo on sijoitettu liian sivuun ja tilanne näyttää usein häiritsevältä.Nenän varjo osoittaa sivulle poskea kohti.
    • Valo tulee liikaa alhaalta: Erityisen kummalliselta valo näyttää, jos se tulee alhaaltapäin. Tätä voidaan käyttää efektinä, jos halutaan saavuttaa aavemainen, pelottava tunnelma. Käytä harkiten.
    • Valo tulee liikaa ylhäältä: Silmät jäävät piiloon varjoihin. Pesukarhusilmät eivät näytä erityisen houkuttelevilta.
    • Valo tulee liikaa takaapäin: Dramaattinen efekti, jolla kohde saadaan vaikuttamaan lähes silhuetilta.

2. FILL light – täytevalo

  • In real world fill light comes naturally as the light reflects to the environment from the surface. If the surface is rendered without GI or radiosity, the digital lighting can’t imitate that property of the natural lighting. The light does not reflect to its surraundings.
  • To imitate this reflective aspect of the light, it is common to use a light source at the opposite side of the key light.
  • When the key light illuminates the scene from up and side of left side of the main subject, the fill light needs to be situated on the right side that way that it reaches the subject from the lower angle. If the lights reach each other in the middle, all of the subject is illuminated. The fill light should not be an exact mirror of the key light. That would make the lighting seem unnatural.
  • If there is another light source (an object such as a lamp) in a scene, the fill light should be placed to illuminate from that direction.
  • The fill light has got multiple uses: it acts as a reflective light, as a light source or as a softening light.
  • Even when the GI or radiosity is used, can fill light be used to make subtle changes to the lighting.
  • If multiple light sources are used, be careful that their illumination intensity is not more than the intensity of the key light.

 

  • Oikeassa maailmassa täytevalo tulee usein luonnollisesti valon heijastuessa pinnoista. Rendattaessa ilman global illumination tai radiosity metodeita, ei digitaalinen valaisu imitoi tätä ominaisuutta. Valo ei heijastu pinnoista ympäristöönsä.
  • Imitoidakseen tätä valon heijastumaa, täytyy virtuaalivalaistuksessa usein sijoittaa valonlähde päävalon vastakkaiselle puolelle. Valon paikan ei tarvitse olla täysin vastaan. Usein täytevalo sijoitetaan kohteen eteen päävalon vastakkaiselle puolelle.
  • Päävalon tullessa ylhäältä vasemmalta, tulisi täytevalon tulla alemmasta kulmasta oikealta. Jos valojen reitit kohtaavat keskellä, se varmistaa, ettei mikään osa kohteesta jää varjoon. Varmista, ettei valo tule täysin symmetrisesti peilikuvaksi. Se olisi luonnotonta.
  • Jos tilassa on toinen valonlähde, esimerkiksi lamppu, sijoita täytevalo siten, että se tulee tästä suunnasta.
  • Täytevalolla voi olla monia tehtäviä, kuten toimia heijastuvana valona, valonlähteenä tai pehmentävänä valona.
  • Käytettäessä global illumination tai radiosity rendausta, tietokone laskee valon heijastukset ja pyrkii luonnonmukaiseen lopputulokseen. Myös tällöin voidaan täytevalolla hienosäätää valaistusta tarvittaessa.
  • Jos käytät useampia täytevaloja, ole tarkkana, ettei niiden yhteisvalon määrä ylitä täytevalon määrää. (key : fill+fill)

3. BACKLIGHT – taustavalo

  • Separates the subject from the background. It creates the sense of depth in the scene.
  • Not necessary. To be used when needed. it is a style choice.
  • Backlight can be brighter than the key light if situation needs it to be.
  • Ideally the backlight is not situated directly at the back of the subject, but a little higher opposite the camera.
  • Multiple light sources are often needed to light the whole edge of the subject.

 

  •  Erottaa kohteen taustastaan.
  • Ei aina välttämätön, tyylivalinta
  • Taustavalo voi olla kirkas, jopa kirkkaampi kuin päävalo
  • Jotta taustavalon vaikutus olisi näkyvä, sen ei tule olla täysin kohteen takana, vaan hieman ylempänä, kameraa vastapäätä’
  • Taustavaloja täytyy usein käyttää useampia, jotta kohteen reunat valaistuvat koko matkalta.

Key to fill ratio – päävalon ja täytevalon suhde

  • Fill light intensity should be considerably lower that the key light intensity, but on the other hand it needs to be strong enough to light the subject sufficiently.
    • Low ratio: 2:1 (key light intensity is twice the fill light intensity) – there is a lot of reflective light and a low contrast between the shadows and the highlights.
    • Mid ratio: 4:1
    • High ratio: 8:1 – Very little reflective light, strong contrast between the light and shadow.
  • Täytevalon tulisi olla huomattavasti heikompi kuin päävalon, mutta kuitenkin tarpeeksi voimakas, jotta kohde valaistuu tarpeeksi. Päävalon ja täytevalon suhteella ilmaistaan valojen luomaa kontrastia.
    • Alhainen suhde: 2:1 (päävalo on kaksi kertaa täytevaloa kirkkaampi) – Paljon heijastevaloa, vähäinen kontrasti valo- ja varjoalueiden välillä
    • Keskiarvoinen suhde: 4:1
    • Korkea suhde: 8:1 – Vähän heijastevaloa, korkea kontrasti valo- ja varjoalueiden välillä

Alhainen suhde

  • Used indoors, where there are many light and reflective surfaces.
  • Cloudy day or a snowy landscape, which lacks in contrast.
  • Preferred light ratio for comedies and children’s programs.
  • Käytetään sisätiloissa, joissa on paljon valkoisia tai heijastavia pintoja
  • Pilvisenä päivänä tai lumisessa maisemassa valon erot jäävät heikommiksi
  • Komedioissa ja lastenohjelmissa käytetään tälläistä valaisumallia kirkkaan ja iloisen vaikutelman luomiseksi. Jopa varjot jäävät heikoiksi.

Korkea suhde

  • Night scenes, there is no diffused lighting from the sky.
  • Horror films, dramatic or thrilling scenes, film noir.
  • Be careful thet the lighting doesn’t distract the viewer from the action.
  • Yökohtaukset, taivaalta tuleva heijastevalo puuttuu
  • Kauhuelokuvat, dramaattiset tai jännittävät kohtaukset, film noir
  • Varo, ettei valaisu vie kaikkea huomiota kohtauksesta.
