Re: Issues Building on MacOS Big Sur (11.4)

With the new MacBookPro updates i'm more than tempted to get one ... but ... it's alot of money. Yeah I was waiting for those one year long but I think for rendering they are not well suited. With the lack of raytracing cores they won't be able to compete with nVidia's mobile cards but being much p...

No idea about building but latest MacOS BlendLux (from 2 weeks ago) works with 12.0.1 on M1 via Rosetta including OCL rendering, which is great!

Re: issue with glass

Looks like I have the issue back on last build : obviously the shadow under the glass sheet is too dark. It does not work with PathGPU + indirect cache alone. It does work with PathGPU + indirect + caustic caches or with PathGPU +indirect cache + bright shadow color (fastest way). BiDir Metro.jpg P...

Re: Luxcore 2.1 Benchmark

it may better to use Luxmark for M1 Pro/Max testing if it work on M1? The user don´t have to install or setup anything for the test, I guess the barrier is to high for non Luxcore user. You're probably right, there was no response. Luxmark results can be found on the web already, I was rather tryin...

Re: Luxcore 2.1 Benchmark

So an M1 CPU is faster than a AMD 3900X (without even been natively compiled for ARM CPUs) :?: Nope, the CPU is about half as fast natively, in LuxMark even worse because of ~20% Rosetta (X86 to ARM transl.) penalty.

Re: Luxcore 2.1 Benchmark

Bought a used MacBook Air M1, base version: 8CPU/7GPU cores, 8GB RAM+256GB SSD (modded with thermal pad). Tested against Ryzen 3900X @ 65W TDP +2x RTX 2070 @ 130W TDP while measuring wall power in Watt. Benchmark scene @ 256 samples, no denoiser, SOBOL progressive is faster for Mac while SOBOL cache...

Power efficient CPU rendering

Interesting comparison of Apple M1 Max, Threadripper 3990X and others rendering massive scenes:

Some BiDir + SDS-cache issues

I'm testing BiDir with SDS-cache on a scene derived from Charlie's Cold Fusion . 6000 samples rendered without denoising, no clamping. All lights, volumes and materials color neutral. Windows 10 PC, Blender 2.93 with LuxCore 2.6alpha. Several issues came up. PrismDisp.jpg PrismGloss.jpg PrismBW.jpg ...

Re: Two well known luxcore problems.

Why go this way if a more accurate less tricky way exist (multi scattering rough glass) ? The tricky thing is probably easier to implement (though I don't know really), and maybe rendering faster? If there is a major overhaul of LuxCore via Cuda-C++ with all new materials before us it makes no sens...

Re: Two well known luxcore problems.

Would it be possible to get a trick like "NO Energy loss" Agreed, in Cycles you can configure a glass material ( using "ray depth" node or sth.) that does not return black after the last bounce but instead switches to transparent and thus guarantees bright glass appearance. If t...
