layer stacking order problem
on Aug 5, 2005 at 6:26:08 pm

I'm having a problem with the way maya displays overlapping layers.
I have an animatic with a guy holding some cocktails. I want some reflections on the cocktail, and so i've created a layer slightly in front of the cockatils with the reflections on it.. (there are all 2d layer planes BTW). So when i'm doing a camera move.. or just moving around in the space, my reflection layer blinks on and off... as if maya is confused about the stacking order of the layer.. i thought i might need to set the tesselation higher for the problem layers, but that doesn't seem to help.. I'm sure it will be fine when i render, but it's really annoying for playblasts and just working in general... any one know how to fix this?

the clip is here:

have you tried moving it up front a little more. Depending on how close it is to the back layer it still may do that. Does it have a experssion on it where it's always facing the camera?

i'd understand if it was at the exact same depth of the second layer, but if you look at this clip:

..you'll see it's set off from the second layer. I assume its an issue with the way Maya uses the GPU to do the hardware rendering... i was thinking there's some setting somewhere that tells Maya how many decimal places to go when checking the depth of an object (to determine stacking order)..

..and no there are no expressions or keys on this layer...

I've experienced the same 'layering' problem myself when working on a GeForce. I never did find a solution, sorry.

Unfortunately, I think this is just a property of the card. You'll notice that Alias recommends against using any GeForce model:
