It is a BiDir-only only problem and it is likely to be related to some wrong PDF (i.e. the weight of the mix between light tracing and path tracing). I'm looking into it (but it is quite complicated stuff).
Code: Select all
if (directPdfW || reversePdfW) {
const float pdf = DisneyPdf(roughness, metallic, clearcoat, clearcoatGloss,
anisotropicGloss, localLightDir, localEyeDir);
if (pdf < 0.0001f)
return Spectrum();
if (directPdfW)
*directPdfW = pdf;
if (reversePdfW)
*reversePdfW = pdf;
}
Could you share the lighting setup (diagram & full specs, if possible)? Unless you already recreated it digitally (1:1), then scene file would be most welcome...daros wrote: ↑Wed Sep 01, 2021 11:41 am I don't know if this helps.
Those are real world samples of exactly the same set-up
Lime only, spehere and box.

Lime only+transparent lacquer, spehere only

enameled cermic, spehere only

Tone mapping of the photos is linear, no highlight compression, almost pure RAW, only white blance, camera Sony Alpha 7 III with 50mm Zeiss lenses.
appreciated!There were a couple of problems but the main reason was this: https://github.com/LuxCoreRender/LuxCor ... y.cpp#L115
