We were talking of the first image, of dispersion and Cauchy's equation: how can be Cycles used as reference if it doesn't support dispersion at all :?: Can simulate dispersion in Cycles with shader nodes, separating RGB chanels using different IORs and adding, summing it back. That is not even vag...

I changed material in your example file a bit... Capture.PNG Yes, i know. The scene shared is set as i left it, after few more experiments to brighten the glass... but got tired and also ran out of time (am slowly recovering from an accident). Also the issue with clear glass might just be the value...

Dispersion example (0-1 in 50 frames): dispersion_LC-21a3-BiDir.gif Roughness example (0.01-1 in 50 frames): roughness_LC-21a3-BiDir.gif To me it simply feels as too dark and I think (IIRC) that glass had much better behavior in previous LuxRender 1.7 (classic&core) version, at least it wasn't ...

Stratified sampler?

I think,
- the smaller the radius, the more samples there are & the more computation is needed
- dark artifacts, from my observations happen only on shadow's edges under some special (?) conditions (most distinctive with shadow catcher used).

Using standard (old) strategies the catcher plane stays barely visible (1), while using DLC strategy plane is fully invisible but strange splotching appears in shadow area (2). I have never tried the combo shadow catcher and DLSC, I'm going to check what is going on. After further tests i found it'...

Hi, sadly, i just can't get it to work on my WS. Whatever i do, i always get the same Error: clBuildProgram Previous version (2.1alpha1) works OK. Error_clBuildProgram.jpg EDIT 1 Issue solved/bypassed! Since only a specific driver version is working with GTX 1060 (387.92 -all later versions throws a...
