illustrator layers not showing shadows on cont. raster
hey all,
I have got a map and some labels in separate layers from an AI file.
the lables are in a precomp that have motion, both the pre-comp and the layers in the pre-comp are set to 3d.
when i put the precomp on the final comp, the shadows appear fine… until you turn on continuously rasterize, then i get sharp lines but no shadows!
all layers and the precomp have the “cast shadows” box ticked.
Im at a bit of a loss.
Anyone know of a solution?
Many thanks!

right i solved the problem, thanks dave for the reply but it wasnt that,
for some reason one layer didnt have a 3d switch on in the precomp,
even though it wasnt the layer that was casuing the problem, that seemed to be the killer.
Many thanks though Dave you do a great deal here!

I think that you encountered the issue explained in this section of After Effects Help:
“How render order and collapsed transformations affect 3D layers”
“The positions of certain kinds of layers in the layer stacking order in the Timeline panel prevent groups of 3D layers from being processed together to determine intersections and shadows. A shadow cast by a 3D layer does not affect a 2D layer or any layer that is on the other side of the 2D layer in the layer stacking order. Similarly, a 3D layer does not intersect with a 2D layer or any layer that is on the other side of the 2D layer in the layer stacking order.”

Okay… I’m having this same problem in After Effects Cs3, but the solution posted here does not work… there ARE no precomps in this thing that are affected by the problem and every layer is most definitely 3D.
The entire composition is a 3d set made up entirely of continually rasterized 3D layers. Some of the layers will randomly not accept shadows if the continually rasterize switch is checked. Changing nothing else, I uncheck the rasterize switch and the shadows appear on those layers. Which layers are affected by this problem seems completely and totally arbitrary. Two very similar trees on the set side by side… one has the problem the other does not. Two similar walls in a building… one has the problem and the other does not.
Been trying to solve this for hours. Wits end. Please help!

Okay… shortly after posting I figured out part of the problem… but it is in itself troubling… vector layers that are continually rasterized AND have effects on them will not be able to accept shadows… but only sometimes. Again, the layers that this is true of seem completely arbitrary. Some continually rasterized layers will accept shadows after effects are applied to the layer, others similarly sized layers with the SAME EXACT effects on them with the same exact settings will not accept shadows unless the effects are turned off. Proximity to the light seems to have no impact. Whether or not masks are applied seems to have no effect. The effects in question are the simple choker, color key, and brightness/contrast… but again, there is no coherent pattern to tell me why the buggy layers are buggy. This is truly infuriating.
I have tried precomposing the layers and moving all attributes into the new layer such that the rasterizing and effects are applied in the nexted composition before the lights even have a chance, but this still will not work. I have also tried disabling open GL previews to see if it was a problem with open GL and point lights… a problem I have had in the past. No impact. But again… why would it if the bug seems to affect layers arbitrarily anyway?
I already have one official bug claim with adobe for a different issue on the same project, and if I submit another legitimate bug they’re going to start thinking I enjoy this. I do not. Any ideas?
