Hi everybody... When I make a render layer, with the color, shadow, difuse, etc... layer, and composed together in postproducction, if any object has a layered shader, in the shadow layer apear Black... What i do wrong?

here is an example with two balls, one with a lambert shader, and the other, with a layered shader with the same lambert and a semi-transparent pong...

Render window...

what software ?

shouldn't affect the compositing if you choose between any shader. can you post all of the layers ??

I used AfterFX and combustion 2... with the same results... :(

so, it renders the shadow layer with a white hole for the right sphere.

did you changed something in the matte opacity settings ??
if not, could you please give just the maya file to look at ?

look yourself... ;) and can you try to make a similar scene with your maya 4.0 to test the same effect?... ;)

Thanks for all Svenip... ;)

really strange and never seen this before. we've had simply everything with layered shaders in our production. really really strange :hmm:

but as workaround set the matte opacity of the layered shader to 0. this helps for now

;) ok svenip... thanks for all... but seting the matte opacity of the layered shader to 0, the object can't receive any shadows... when a object ocluses the light, the shadow isn't cast over the layered shader.

I found another workarround, and it's simple. Only maping the outcolor node from the layered shader to the color of any other material, like lambert, blinn... the layered shader take a little diference from the original, but the shadow layer works fine... ;)

thanks for all svenip... and... wow... 464 posts are a lot of posts... :beer:

i tested some minutes around today and can't find out why this happens. this problem has never come along to me, even if we use only layered shaders :hmm:

but nice workaround you worked out. haven't thought of this :).
