I want to make a solid layer to project the view from a camera using expressions.
In "comp A" I have a camera pointed at some 3D elements. Now I want to make a solid layer in "comp B" and add an expression to it, that makes the solid show what the camera in "comp A" sees.
I'm only interested in solving this problem with expressions and existing effects within AE. I don't want to insert "comp A" directly into "comp B".
Besides pre-rendering "comp A", I can't think of anything that would give a more efficient result than just dragging it in. Can you shed some light on your reasons for not wanting to do so?
You could, for instance, create a new solid in "comp B". Drag "comp A" into the timeline and turn the visibility off. Add the "Set Channels" effect to your solid, and then choose comp A as the source in each channel. This would give you the image of comp A on the solid. However, I can't think of a reason why this would be better than just using the comp itself.
