c’mon admit it… no-one REALLY understands ‘collapse transformations’…
I have some simple 3d layers (including text) with a single camera and a single light. I have pre-composed these layers and used my main comp as an assembly of the pre-comps. The motion works fine, the masking works fine (miracles!)… however, the lighting/casting shadows/edge quality does not work fine. It is very far from fine.
Sometimes checking ‘ct’ lowers the quality of the layer but a shadow is cast. If I uncheck ‘ct’ the quality improves, but the shadow disappears. Then the way a light affects a layer changes; with ‘ct’ checked and the shadow casting, the light level falling on the object is about 50%.
I say ‘sometimes’ because I don’t see a consistency. Why does a comp that contains only 2 layers (a masked solid and a text layer) look awful when it’s pre-comped twice (dropped into another comp which is then dropped into the main)?
I know that nesting comps may be unnecessarily complicated sometimes, but here it’s not and besides if I go through the whole structure and make sure everything is 3d and set to best with ‘ct’ checked, then everything should look dandy, right?
Yeah, right.

Like Dave said – the problems are of your own making. CT will do exactly what it says – it will collapse transformations which translates to anchor point position, position, rotation and scale. Nowhere is it written that it will pass thru lights or other fancies and since AE will still see any collapsed compositions as a single layer, it’s only logical it will assume a certain default anchor position. I’m not saying it’s perfect and AE definitely acts pretty dumb and slow on anything remotely complex in 3D space, but it should not be too difficult to understand the concept.
