3d render engine is frequently wrong?
AE CS3 8.0.2
OSX 10.5.5
2×2 Ghz Dual Core Intel Mac Pro
3gig ramHere’s the thing. I’m frequently getting incorrect display of my 3D layouts. Recently I have a 3D box coming up through a flat floor. On the floor is an outline of a square. The box is coming through the floor and inside the outline of the box. Looks great on top view. But sometimes on custom or camera views, the box moves outside of the outline. There’s no trick of the eye here as it can only intersect at one spot, which is pretty apparent as it disappears into the floor.
Other elements might be some text laying flat 1 pixel above the floor. As you move the camera around the scene, the text will vanish into the floor from some angles. I’m just moving the camera around in custom view usually to see the scene from different angles. But if you animate an actual camera in the same fashion, the text will vanish there too.
Seems like the rendering engine kinda sucks in CS3. I’ve had various oddities that are all similar in nature in different projects. Is there some fix or something I need to toggle? A render correctly option?

DUDE! Learn the software – IOW RTFM!!!
Placing objects in 3D space requires more than one view to ensure that you are indeed placing an object at a specific spot in 3D SPACE.
Four tips for U!
1) AE only renders the view from the topmost active camera.
2) Use OTHER VIEWS ONLY AS A GUIDE
3) USE OTHER VIEWS when placing layers in 3D space[Bret Williams] “A render correctly option?”
4) RTFM!Cheers

Wow. What a complete…
You know I’ve been using the software since version 3.1 and I create some pretty nice stuff. I know my way around 3D and can’t really see what in my post prompted you to think I’m a beginner.
AE has always had issues with it’s 3D rendering engine since it’s inception. It’s never been perfect, but these issues are new ones to me. Since my issues occur when Previewing and Rendering it’s not dependent on particular views. It has to do with problems with very complex 3D intersections.
As I pointed out, even on a non-animated piece, where 2 planes or boxes, or layers, etc. intersect, they may or may not intersect based on the camera position. IOW they actually change position by only a pixel or maybe a half depending on the camera angle. Shouldn’t happen. It does. I can upload pics to my site after work.
Surely someone with some helpful info that read my first post fully and grasped what I was talking about (I know it was shoddily written) might have some thoughts.

Hi Bret, apologies for the rather harsh reply earlier. It did seem like you were ranting on something rather basic that is the result of user-error more than anything. This is me speaking from experience here at the COW.
Oftentimes, such errors are the result of folks using the Standard 3D renderer (but that’s no longer used in CS3) plugin and placing their layers wrongly. I would first look the 3D placement (position)of your layes and also take a look at their orientation (or rotation)to ensure that the layers share the same values.
Other than posting the pics, perhaps you may want to also upload the AEP. I can’t promise you that I nor anyone else will be able to sort things out for you but the AEP will provide better answers.
Cheers

Can’t really post anything since it would give away the company and the project and it deals with a new sales program. So not a good idea to put it out there for their competitor.
But I’ll create a basic 2 or 3 layer version and see if I can duplicate it in a project for all to debate. I’ll post it in a later thread.
It might just be a workflow issue. I do a lot of parenting and nesting. For some reason this seems to cause problems in either CS3 (could be a OpenGL thing) or OSX Leopard. I don’t recall ever having the issues before that except before the Advanced 3D renderer.

Yup that sounds like a plan. Also, perhaps deleting any branding and redundant layers may be a faster thing to do rather than starting from scratch to re-create te issue.
Cheers
