HI there.
So I'm trying to create some curtains, this is the material:
CPU Render:
OpenCL Render:
Exact same material, exact same object, exact everything.
@dade @B.Y.O.B. Any ideas of what is happening? something is not working or is broken with OpenCL right now.
Something is off with translucency in OpenCL

Re: Something is off with translucency in OpenCL
Mixing a solid material (like Disney) with a transparent one (like glossy translucent) can be a recipe for a lot of troubles: does it happen if you use the glossy translucent material alone ?
Re: Something is off with translucency in OpenCL
Yes, it seems the problem is the mix of translucent and disney, there is a difference in brightness when you mix that, I have not tested with velvet or matte, will do.
How can I achieve a translucent curtain feeling without breaking laws of physics? hahaha

Re: Something is off with translucency in OpenCL
Have you tried to use Disney with just some transparency (or opacity, I don't remember how it is called in BlendLuxCore, it is a generic material setting available for all LuxCore materials) ? It would, by far, the fastest solution to render.
Re: Something is off with translucency in OpenCL
It's what I'm doing right now, but it looses the effect of the ligth scattering that make you perceive the window border, but in a blurred/diffuminated way, like in some real curtains, with transparency in the end we get the hard border of the window, so the effect is not the same
