Re: infinite plane

Can we have infinite plane in luxcore? Like a dedicated shader/object that represents endles plane, for ocean or endless ground etc.. Sky2 light source has such a thing (ground color, etc.) but I assume you are looking something where you can cast shadows, etc. Any particular reason to not just use...

Re: long triangles

This keeps coming back again and again. opencl trianglesGPU.png cpu trianglesCPU.png even on cpu some very thin and long triangles show up black! It's just that opencl is more sensitive to the issue... It almost looks like some overlapping is happening.. raising min epsilon won't help and main scen...

This looks fantastic, how about long flat planes with bump, won't they look like they collect dust?
Your test scene seems to work fine with the new version:

Re: Light Intensities and Units

I wanted to let you know that I updated Photographer to work with Cycles and LuxCore: https://gumroad.com/products/FWQf Chafouin, if you want, can write a "News" in forum news section (just update the addon description "This add-on adds new Camera settings for EEVEE and Cycles" + LuxCoreRender ;) ).

Re: Shadow Terminator problem

After some comparisons I think again, that something is not perfect with LuxCore bump mapping. Left side is highly subdivided and has displacement modifier with the bump texture. Right side is low poly and has bump mapping with the same bump texture. Cycles: bump-test3-cycles.jpg LuxCore after shad...

It is Not the Glass Container, it is the Glass Itself :!:
You need to have half of the juice directly visible to notice the difference (like in the original test scene). In your test, all the juice is under glass shadow.

Re: dark juice

I think to remember that I read in this forum that when you rewrote LuxCore you decided to use RGB rendering for performance reasons and calculate dispersion in the core from RGB values instead of tracing > 10 wavelength bands like spectral renderer do. Old Lux was tracing 4 sampled wave lengths an...

The node setup in Cycles (variation of the IOR for R,G, and B is exactly what LuxCore does automatically in the core)
Uh ? No, LuxCore sample exactly all the visible wave lengths but only if required. Cycles trick produces a far worse results and it is totally inaccurate.

If the light source is not intersectable, why don't we make the eye point intersectable?
It has been done only on some research renderer (for instance Mitsuba), the probability to hit the eye is so low, for a light path, that has very little practical application.

I merged CodeHD's patch and now all versions use Intel Oidn v1.0.
