Bake animation layers lets you bake (or Plot) animation layers contained in the incoming file.
If your incoming file contains animation layers, make sure that this option is activated so that the plug-in considers all animation curves. This process bakes all layers to the base layer and makes them compatible with 3ds Max Curve editor. This option is Active by default.
If you disable this option, the plug-in imports only the Base (or first) layer of animation and ignores all additional layers.
If there are no additional animation layers in the file, you can leave this option active with no effect.
