Re: LuxCore AOV outputs are strange When using few spp(1spp)

Check the scene intersect function: https://github.com/LuxCoreRender/LuxCor ... e.cpp#L585 As you see the ray is continued to trace if the "!transp.Black()". Now check material "bsdf->GetPassThroughTransparency(backTracing)": https://github.com/LuxCoreRender/LuxCor ... al.cpp#L87 The material is so...

Re: LuxCore AOV outputs are strange When using few spp(1spp)

First of all, thank you very much for your patience in answering my questions. Sorry for misunderstanding the reason Zeealpal linked. But, I still have a few doubts(I'm a rookie in this field :oops: ): 1. I still think that the geometric channels' outputs are unrelated to the material properties(If ...

Re: LuxCore AOV outputs are strange When using few spp(1spp)

Thx.
But I think that Geometric channels outputs are obtain and saved in sampleResult when camera rays are intersected with object at the first bounce. In my perception these channels' outputs are independent of material.

As the picture showing, there are some larger white spots and lots of gray spots in POSITION Channel picture. And there are some black or gray spots in ALBEDO Channel.
What is the reason of this phenomenon。
