bidir vs Photon GI (CPU) Some tests which do not make me wiser. All glass surfaces have white shadow.

I didn't had the opportunity to make some more scientific tests or accurate comparisons. For the moment i followed the advice of sharlybg, to vary the sun color temperature: This is the reference HDRI result which seems great to me. I have many blue sky HDR's like this and all give more or less the ...

That's really cool! Thanks Nyck and Sharlybg!

We just implemented in FELIX Luxcore's panoramas. Here are the first tests: Only 4K resolution, full bidir, ACES, mostly with volumetrics. https://momento360.com/e/u/81915793cb0548b0bd9fa21402db80e3?utm_campaign=embed&utm_source=other&heading=0&pitch=0&field-of-view=75&size=mediu...

Ok... i think i have to make some more tests to see if our implementation is correct and then i come back to you. Thanks for the moment!

Hi Dade, i tried to put the sky color at 12k kelvin and still the cyan dominance is strong. i cannot get a deep blue sky. ACES off sky no aces_1.jpg ACES on sky ACES_1.jpg however at cycles i see a similar behaviour... or at least time ago. https://devtalk.blender.org/t/new-sky-texture/12708/528?pag...

Hi Kintux, the following is one of the many many tests we did in order to tune ACES as good as we could to match linear. No tricks, just applying the theory trying to avoid mistakes. The only thing i did was to adjust in post the exposure of the Linear in order to match roughly the greys of ACES. If...

No post production, raw output using ACES.

Hi Dade, we have started to study Lux's code but we didn't understand what we need to do to make the physical sky work with ACES. Can you give us some tips please about how to intervene? This is with no ACES no ACES.JPG with ACES ACES.JPG In all other situations we get close to perfect results.
