– Is there a way to make possible for the Shatter fx text to cast shadow ? (I’m using here the first light of comp.)
If you Pre Compose the shatter layer and make the PreComp 3D it will cast shadows. You’ll need a light in both Comps. With a little expression trickery you can have the light in the Shatter Comp use the settings from the Master Comp.
None of these solutions is ideal, they’re just work-arounds. Even Zax won’t cast shadows properly on AFX layers, you need to create another plane in Zax to accept the shadow.
