AE Layers Vs 3d space
hey all-
I’m animating a pov shot of a vehicle going through a forest in 3d space.
This means that the camera is moving on a 3d plane, twisting and turning along a winding road, as it passes trees (perpendicular planes in 3d space).
The problem I’m having is that, regardless of 3d space, AE renders the layers one after the other- so that if I have the winding road layer on top of the tree layers, the road is always on top, no matter what actually might be blocking the road from the camera in 3d space.
Trying to compensate for this has gotten me into a mess of precomps w/collapsed transformations- Trying to sandwich the road between two comps of trees, and mask out the trees where needed.
But the Pov camera makes the perspective constantly change.
Any ideas from anybody?
Have I dug myself into a hole?

Sorry, no 2d layers.
Nothing to get rid of. If only I could use that trick to divide the AE rendering process in a useful way!
Thanks anyway Dave.

Hi Rich,
Have you set something on the layer’s blending mode?
If you’ve activated it, it might be messing with your render order.

Thanks for the replies!
I double-checked that all layers are 3d, no blending modes are on. I also ended up turning off all the effects and collapse transformations to see if that had any affect. And there’s no Kilroy/shyguy layers hiding about.
I think I’m trying to make too practical of a world in AE… shoulda used a 3d app.

I think I found the culprit.
the road had an alpha matte applied to it in photoshop- when I merged layers in the photoshop doc, the intesecting problem i was having in AE disappeared.
guh.
there went a good part of the workday.
Thanks guys for the replies!
