Rendering/Previewing Mystery
Hello all,
I’m pretty stumped regarding a problem I’m encountering in AE 7. I’ve created a composition with quite a number of layers (30+) and a light that involves some flashy text and some 3D rotation, etc., etc…
To jazz it up a bit, I thought it would be nice to apply some motion blur to a few select layers. Naturally, I anticipated a slow down in rendering time, but I had already timed out all the movement and got everything looking how I wanted it. The motion blur was just some icing on the cake.
Trouble is, once I apply motion blur to the layers, everything starts to render funny. Layers that were fine before start to disappear and reappear in inconsistent intervals. As long as the motion blur is off, I can preview and export from the render queue and everything looks fine. But once I enable motion blur, it won’t preview correctly, nor will it export correctly.
Is this a known issue? Does anyone here know what might cause such a problem.
My computer has 2Gb of RAM, my video card is a BFG NVidia GeForce 7800 with 256Mb.
I know that there can be rendering glitches while previewing if you use OpenGL, but I’ve got fast previews turned off and I still get problems.
Thanks for any help anyone can give me.

Are you using Advanced 3D? Do you have a real camera in your composition? I#d check that first, as what you descrribe sounds like a generic Z-clipping issue.

Advanced 3D is on. I’m not entirely sure what you mean by a “real” camera. If you asking whether I’ve added a camera to the composition, rather than just using the default camera, then yes, I have.
I agree though, it seems to be a z clipping issue, though I don’t have any idea how to fix it. I’ve rendered the whole thing a few times with and without motion blur, subtly changing some export settings and upon multiple viewings, I’m reasonably certain the layers are disappearing and reappearing at the same frames every time ~ in other words, it’s not quite as random as I had originally thought. It still think it’s a glitch though, a glitch that produces the same exact mistakes each time I export or preview.

Mmh, if you are rotating stuff, it might be the small chance that due to the subframe sampling of the moblur it is viewed edge-on, effectively disappearing. Perhaps shift around stuff a tiny bit???
