Finger prints on glass, using roughness:
Re: Dirt/Fingerprints on Glass
From my testing as you can see at the beginning of this post, using rough option makes the glass quite darker.
Re: Dirt/Fingerprints on Glass
Yes, i too found it too strong at first. But that's why "Math Divide" node is there, to lessen the effect.
PS
Here I divided by 25 & set Glass Color to pure White: & Divided by 50:
Re: Dirt/Fingerprints on Glass
Thanks kintuX,
Here is another test using rough option.
First image regular glass
Second image rough option enabled, roughness set to 0.001(lowest I can set)
As you can see, something is not right.

Re: Dirt/Fingerprints on Glass
Why not mix glass with matte?
Also instead of a texture driving roughness directly the texture could mix clear glass with rough glass (instead of matte), minimising the darkening effect.

That works well! Thanksepilectrolytics wrote: ↑Fri Apr 05, 2019 9:06 pm Why not mix glass with matte?

Re: Dirt/Fingerprints on Glass
I should have fixed this problem: it was a bug when using glossy coating with pure specular materials (i.e. glass, mirror).
Re: Dirt/Fingerprints on Glass
Maybe this fix is not yet in BlendLuxCore, or it's another bug, or not bug at all.
The rough glass with roughness of 0.001 has very strong transmissino color. Set the reflection color to pure red, and roughness of 0.001.
Mixed with clear glass, you need mix factor of 0.000001 in favor of clear glass, to make the rough glass red transmissino color fade out.

There are no changes required in the Blender addon to use this fix.
However, the latest daily build does not yet contain the fix: https://github.com/LuxCoreRender/LuxCore/commits/master
