Maxwell 3.0.1.3

Black bars appear on the render randomly. with no additive layer material.

if you render the same mxs, multiple time. sometimes horizontal bars appear sometimes not.

does anyone know what could be the problem ?

This could be caused by excessive trans esp in sss materials, try with all transparency under 242 values, that fixed the black bars for me once, using MW2.

Do you have a scene always producing them? Please send it to tom|nextlimit|com

Instead of opening a new topic I'm going to bump this thread up.



I have the same problem with multiple scenes. Those scenes use the same models and materials and some of those materials are SSS ones. I tried lowering the transparency value to below 242 and it didn't work.
When I use the GPU preview the black bars disappear but the noise increases and you also can't save a preview image.

Are there any other problems with SSS materials which I should avoid?

Also, I can send the scene to you Tom if you want.

Tok_Tok just upgrade Maxwell and plugins which you use to the latest version. Problem is fixed.
