Hello to all,

I have a trouble with transparent material.
I drawn a cap with 1mm thickness Black lines appears in the thickness by transparency, it makes it unrealistic,
I tried everything I had in mind (redrawn a similar volume, uncheck fake shadow, flip normals, change environment, diffuse and specular depth, use pmc and pathtracing)

Do you have any Ideas that I mess, please ?

Thanks a lot,

1 mm is pretty thin. The first thing I'd check is Ray Epsilon in your Kernel settings. It is a scene- and object-scale sensitive attribute.

You are right, this does help !
Thanks a lot
