The Exportor options:

Scene scale
Default=100:
Collada scene values exported from After Effects tend to be fairly large. Use this value to scale down the exported scene.  100 will scale down by a factor of 100.

Include zero value rotations in scene node?
Default=Yes:
If a layer's rotation/orientation has no keyframes and has values equal to zero then it doesn't contribute anything to the scene or animation and can be ignored by the export process.

Export marked layers as joints?
Default=Yes:
The collada importer will add a joint comment expression to a null layer's light transmission attribute to indicate that it came from a collada joint node. The exporter can read this comment and export a skeleton joint node instead of a null node.

Notes:

• The animated tracks should be baked to ensure a predictable transfer via collada.
• XSI Mod Tool seems to require all rotations so is incompatible with the include zero value rotations option.
• Lightwave prefers yxz rotations
• Lightwave assumes yxz order if only 1 rotation axis.  This behavior allows the brute force import to act as a go between for collada files from other programs and Lightwave.
• Be sure to set the frame rate of 3D application to match After Effects frame rate.
• The exporter is hard code limited to 4096 layers.
• 3dsmax import won't see the collada camera field of view unless it is animated.
• Cameras that use the point of interest target are not supported(see next line).
• A version of Ryan Gilmore's camera animation baker can be found on this page.

 

After Effects bake for export
1. create keys as needed
2. activate expression - no changes
3. animation - keyframe assistant - convert expression to keyframes
