glossy translucent and bump

[Dade]

I may have been able to reproduce the problem, with bump map:

without:

...it would be a lot easier to investigate with a simpler scene.

Here is a simple test scene.

I get this rendering with glossy translucent:

and this with matte:

where is the problem in glossy translucent ?

I modified provisory's scene to better show the problem

just enable/disable bump to see what's up

bump on:

bump off:

as you see translucency is not working with bump

I thought it was quite visible in the original scene...

I should have fixed the problem. The shadow terminator fix was cutting transmitted light. It wasn't a glossy translucent specific problem but something affecting all diffuse/glossy and transmitting materials.

Thank you!
I'll test it when it's released.

Looks fine now.

Hmm, it doesn't work for me, and the file dates in the build are yesterday morning...

I think the deployment has failed:

The upload of files to GitHub failed, I re-deployed the files and now they should be all up to date.

It works fine now!

With the previous version I could reproduce the problem with rough glass too, but that is also good now.
