Render layers/masks?

OK, I will try and explain this as best I can!

I am trying to render two animations from the same scene to bring into AE, each containing a different set of objects. Is there a way to render each animation with the other object masking the current object when it is in front? As if to render the scene then subtract the objects not selected, so where they were it simply shows the background.

I have had a play around with Nodes but no luck so far… im sure its something to do with alpha and maybe subtracting render layers but I cant quite figure it out.

Cheers :slight_smile:


I’m not sure did you want exactly that…but hope this helps!:rolleyes:
Just replace nets from Alpha Over node and will “switch” one layer over another!
All the best!

Why not simply append the two Blender scenes together and then render out your footage from a master scene?

Thanks for the .blend and suggestion, I will give them a try when I get back home later today.
