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...

Yes, you go out of visible spectrum out of an healthy range. See https://en.wikipedia.org/wiki/Cauchy%27s_equation (upper right image) for values on visible spectrum. Thanks, all that got me thinking again... Roughness (0-1 in 50 frames) with Cycles 'MultiscatterGGX' Glass CyclesMGGX_GlassRoughness...

Also the issue with clear glass might just be the values that you are using. The tool tip for dispersion says: "Realistic values range from 0.00354 to 0.01342" Yes, you go out of visible spectrum out of an healthy range.

How can you render caustics with path engine?

If the light source can be intersected by a ray (like area lights, sun or HDR), it can be done (even if most of the times will produce just a lot of fireflies if the light is not very large and easy to hit).

Downloaded latest source code. Trying to install from source on macOS High Sierra 10.13.6. In the downloaded folder I run "cmake ." then "c" for configure. I get the following error: CMake Error at CMakeLists.txt:79 (MESSAGE): --> Could not locate required Boost files - Please check /Users/alaganow...

I'm really excited about the further steps and development of LuxCore 2.0+, so big thanks and greetings fly out to the dev-Team *thumb up* I tried my very best to install any of the 2.1alpha-releases, so also BlendLuxCore-v2.1alpha3-win64.zip BlendLuxCore-v2.1alpha3-win64-opencl.zip but still could...

how this could impact GPU rendering ?

If it is exposed trough some usable API (anyway, at the moment is just marketing vaporware, they haven't disclosed any detail about what is really in there).

Sadly luxcorenetconsole seems to only accept the bcf files, so no cfg files with simple editing.

You can use luxcoreui to convert any scene in .bcf format

I'm playing with rendering of prisms for nice rendering of dispersion and just rendered on multiple nodes in my home network today to get a decent resolution testfile. The scene was build in blender and I exported as a binary file. Lux ignored the setting of multilayer exr as the output format and ...
