Problem with the reflection pass and After Effects
Hi everyone… I got a question about compositinh with After Effects…
Here, I create a sequence in Cinema 4D, but I want to comp it in After Effects rather than using the compositing abilities of Cinema 4D (for further post-treatment)…
Si I’m using the Compositing Tag, the multi-pass render, with the Object Buffer, the Shadow Pass and the Reflection.
I have two reflections on the scene. One on the floor that cause me no trouble… I blur it in AE and that’s done. But I have a mirror two and in the comp created for AE, all the reflection passes are with an Add Transfer Mode… So it’s kind of semi-transparent, which is not working for a mirror reflection. I managed to use the Set Matte and played a little with the Alpha Levels in AE, but if the object reflected is black, then I won’t see anything at all in the reflection pass.
So I was wondering how to create a reflection with an alpha channel maybe, or how to render only the reflection and not the object that reflects, or anything like that…
Thank you.

i have no idea if this would work, but its worth a shot.
BUT. if you put a compositing tag on everything but the mirror. (and uncheck everything but seen by reflections). THEN you add the diffuse layer to the multipass, and render it to a new name.
import that to after effects, then using the diffuse (transfer mode>stencil alpha) ON TOP of the reflection layer (which is now set to transfer mode>normal), it should cut it out nicely. then just drop THAT comp into the previous, and voila!
