Hard to say without a scene. Are there any warnings in the VFB log? Could you attach (or send) the simplified scene so we can take a look?

Thanks for the provided scene. Everything seems to be in order. Your VFB Source was set on “Composite” so you have to wait until the IM and LC are calculated to see the results (channels are previewed in the rendering phase). If you switch the Source to RGB, you’ll see the result. Also, note that LightMix is not supported together with IM, so after you adjust the scene’s lights, you should transfer them to the scene (To Scene option).
