Figure 1: Specifying Render layer IDs in After Effects.
Render layers allow for scene geometry to be separated into parts, where one part is meant to be visible and the rest of the other parts “capture” the side effects of the visible geometry on it.
Figure 1: Specifying Render layer IDs in After Effects.
Setting up render layers is done in the OctaneVR window. An Object Layer Map node is added and connected to the input of the GeOut node. The scene geometry node (screws.obj in the following example) is also connected to the Geometry input on the Object Layer Map node. Finally, an Object Layer node is added and connected to the appropriate input on the Object Layer Map node (figure 2).
Figure 2: The node connections for a render layers setup.
Choose an appropriate Render Layer ID number in the Object Layer node (figure 3). When this ID is selected as the active layer in After Effects, this object will be the only object that renders (figure 4).
