- To manipulate a layer in 3d space, click inside the "3d" check-box of the layer (under the cube symbol).
- When changing the Z-position of a layer, a negative value will bring an object closer to the "default camera" and a negative value will move it farther away.
- Play with the appearance of your 3d layer using "Material Options" (effective when using lights)
CAMERA
- Camera Settings:
- Layer > New > Camera
- A camera will affect only 3d layers
- Use the camera tool ("c") to quickly manipulate the camera
- For better camera control, work with 2 or more views (bottom of the "Composition" window) with each view set to a different angle. Note: only the "active camera" view will render.
- Camera Animation–Transform attributes:
- Always set keys to both Point of Interest and Position
- Point of Interest: the direction in which the camera faces (the "bulls-eye" dot, best accessed from the top or side views)
- Position: The actual location of the camera
- Whenever possible, limit yourself to keying only the Point of Interest and the Position. Most camera moves can be achieved without using rotation attributes.
- Camera Options:
- Zoom: always use Position to get closer to or farther away from an object. Use zoom only for situations when Depth of Field is turned on and you want to preserve the blur levels of your background/foreground
- Depth of Field: blurs objects based on their proximity to the camera. Depth of Field can result in unmanageable render time. In complex scenes, it is sometimes easier to fake it by manually applying the Blur effect (Effects > Blur and Sharpen) to individual layers
- Focus Distance: sets the values for Depth of Field
- Aperture: play with it to get different blur results
- Blur Level: controls the strength of the DOF blur. Using a value greater than 100% can result in undesirable pixelation.
LIGHTS
- Layer > New > Light
- Spot Light: offers better controls, similar to those of the camera (Position/Point of Interest)
- Like cameras, lights will only affect 3d
- Casting shadows:
- on the light layer: light options > turn on "Casts Shadows"
- on the object layer: material options > turn on "Accept Shadows"
- control the shadow appearance on the light layer > light options
- to cast shadows, the casting layer must be next to another 3d layer which has "Accepts Shadows" turned on (usually on by default).
