transparent material + wood artifacts

Post by zooropa » Wed Sep 16, 2020 7:21 am

Hi. I am dealing with a new scene and I am getting some strange artifacts on some of my meshes.
I believe it has to do with the intersection between the acrylic glass and the wood. I am not sure if this should be the expected result when this happens.
Unfortunately the render looks better when the meshes intersect, I would like to keep it like that.
I am using lux 2.5

Thank you, can i ask how did you solve this. I checked the link, but I need to render within Blender.

Try to delete and rebuild the wrong face hand hope it will not happen elsewhere. It is a bug and Devs will look into it.

It may be not the same problem, Zooropa, just try to rise a little the glass top: if the surface of the glass and wood one are too near, due to limited floating point 32bit precision, LuxCore may detect the intersection with the glass plane and not with the wood surface (so seeing inside the closed wood box: just all black).

I would say the same as Dade. Objects with transparent materials, can´t touch other surface, because renderer don´t know what face it should renders.

Thank you. I was doing like in cycles, where they worked. Now I know, after moving a bit the acrylic glass I stop having those black artifacts.
