Flickering 3d layers
Posted by Layne Haacke on July 2, 2007 at 3:02 pmwhat am I missing? I have parts of 3d layers that flicker darker then lighter as I move the camera (I have a light source and I’m casting shadows)
there is no other 3d layer near it.
It’s not the advanced 3d rendering.here is what it looks like one frame to the next

July 2, 2007 at 3:34 pmare there any other effects? it sort of looks like what broadcast safe can do to colors as the change to illegal values.
also, are you seeing this in preview or final render? and is opengl off? it could be a codec thing, or opengl issue.

No other effects.

–codec thing, or opengl issue.it does it in preview and final render.
It’s there only when I have the light “cast shadows”.
If I turn the “Casts Shadows” off in the light source then it doesn’t do it. -

July 2, 2007 at 4:14 pmi noticed that, in the grouping with woman and the 1, that the upper right house doesn’t flicker… is that the upper most layer of that grouping? and are all of those layers on the same x-y plane (same z depth)? it seems like ae is trying to cast shaddows of each of those layers on each other even though it shouldn’t. placing empty adjustments layer between the 3d layers may help ae render coorectly.

July 2, 2007 at 5:33 pmAdjusting the layers depth is taking care of it, I’m putting all the layers a pixel or 2 off (it seems in this case the higher (y value) ones need to be behind (z depth) the lower ones. It’s trying to cast a shadow from above.
Puting adjustment layeres between makes it so the shadows don’t render at all. I’d have to play with that some more to see if that would work.funny that all the other layers don’t do that.
Thanks,
Iv’e been around AE a long time but sometimes with frustrating things like this…
I feel like the newbie. -

July 2, 2007 at 6:06 pmjockeying the z-positions was going to be my next suggestion… or maybe precomping the what appeared to be groups of icons and people sow the entire precomp would be casting a single shadow, but i wasn’t sure of your comp structure.
anyway, i’m glad its working now.
3d isn’t exactly ae’s strong point, they seem to have a few things to iron out. cs3 may make things better.
