Re: Can't Get LuxCoreRender to work with Blender MacOSX

BlendLuxCore v2.3beta1 works with Blender 2.81a on OSX 13.6 on my MacBook. Blender 2.82 does apparently not yet work and OSX 14 and later would need a notarized LuxCore which is not there yet.

this fix may also have some unexpected implication like fixing the light tracing brightness variation on animations has been reported few times

Light traced caustics still not constant :(

Barely 5000 samples :?
It just dawned on me that the problem with the incoming light could be easily solved by putting a glass pane in front of the emitting plane, outside of the screen.
Then it will be a caustic beam like the rest and rendered quickly with light tracing :idea:

Re: Spheres scene challenge

Yep, while light tracing is faster than BiDir, path tracing (of the volumetric scattering from the IES light) is way slower than BiDir so that it makes no sense to render it this way. I wonder why adaptive sampling (with Sobol) is not catching this. I think there is already an implementation for use...

why is the mirror material mixed with metal?
Mirror material is too perfect for my taste so I mixed in a reflective material with a little roughness to create a bit of a light halo on the mirror surface (did not turn out very well).

Re: Spheres scene challenge

I didn't save that one, but was able to recreate it for v2.3beta on Blender 2.81a. The "incoming beam" directly from the IES light is not rendered by light tracing (because no caustic before going through the first sphere) and therefore extremely slow to converge. I did never finish this render but ...

Re: playing with caustics

Comparison of render with caustic cache (first turn) versus light tracing with SDS-cache (second turn). Caustics from cache seem too bright and there are fireflies dancing in the shadows that OIDN cannot catch, also render times are way longer. Caustics from Hybrid engine seem more natural but brig...

Re: Animation render abort

Thanks @FarbigeWelt for testing and confirming!
Good to know I'm not the only one experiencing this (and it is not an nVidia issue).
Also the caustic brightness variations are visible in your table.

But when Dade cannot reproduce this on his system he cannot fix it.

Re: Triplanar mapping / stochastic texturing

Works great with textures and bump, but I can't get normal maps to work (wrong intput warning and no visible effect).
