Re: Windows build deps

Should it help keeping all deps updated to latest versions? I actually don't know myself, if vcpkg is better or not for luxcore. It sure built all the dependencies that build-deps-x64.bat failed to build. Even so, if i had all the deps built, i got over 1900 errors by just manual copy paste new lib...

Re: control brightness of glass material for Diamond

Re: Random optics stuff

With no lens formula it's hard to get the lens in focus. I played little with the Zeiss ZM 35mm 1.4 Distagon design, but the Meyer Optik Görlitz Trioplan looks interesting. It's a 3 element lens with soap bubble bokeh like below: https://www.meyer-optik-goerlitz.com/media/image/b1/48/1e/meyer-optik-...

Re: BiDir Hemi bug maybe

It's somehow related to multi scattering with BiDir and this commit https://github.com/LuxCoreRender/LuxCor ... aed3bf5cfb
When i revert the green lines with pink lines, the luxcore ui at least loads the scene up.

BiDir Hemi bug maybe

BiDir Hemi bug maybe.7z In Blender cpu random path works, but cpu random bidir not. Bidir speed drops fast, Blender ui gets sluggish, can't stop render. This is with hdr hemi lamp, low res or high res doesn't matter, if multi scattering is enabled. Luxcore ui gets also locked, can't even set render...

Re: Cold Fusion

:) Perhaps the rough glass and clear glass mix material was causing noise with BiDirVM.
With simple clear glass all the noise is gone, well 99,999%.

Re: Cold Fusion

For classic engine it seems like smaller scattering value works better, or asymmetry value more forward scattering like 0.8 or 0.9 Then it's less white. I got good speed up by moving camera closer to subject with wide angle lens 15mm from 70mm and making the scattering room / cube smaller. Also i ha...

Re: LuxCore standalone questions

:D Changed the theme colors a little. Aquamarine font color, black title bar changed to bluish gray, tripled the corner rounding.
