Re: CIE 171:2006
Hi, I've just finished my first attempt for the first (out of 12 or more) test cases. If my process is correct, there seems to be a serious issue with working with IES files. Please have a look into the attached documentation and the corresponding blend files. I'm happy for every oppinion and every ...

Re: Material/Texture rework in v2.3
Hi, My wish for materials/volume nodes would be a way to define them more physics based. Old lux was able to read spectral absorption curves for volume colour. Also refractive indices curves for dispersion were possible... How is about integration of physics based scattering models like (Heyney Gree...

Re: Swimming pool / Underwater / Caustics
Hi all, One more question from my side. You said SDS paths are impossible to render with BiDir... But is it really impossible or just hard to render? I'm wondering because the images look quite good, what are you missing? Physics based render is always connected to some patience... remembering older...

Re: CIE 171:2006
Hi, I bought the document, but I think I'm not allowed to share it. It mentions a range of test cases that should compare the calculated/simulated results with some analytical and measured values. Within the next days I'll gonna try to run through each of the tests with luxcorerender... Are you inte...

Re: CIE 171:2006
Yes, that's why I was hoping that someone knows about its content already.

CIE 171:2006
Hi,
Does anyone know about this CIE 171:2006?
It's a report that handles "Test cases to assess the accuracy of lighting computer programs".
Do you know how luxcorerender will fit into this?
Thanks.

Export of denoised light group layers
Hi
I'm working on BlendLuxCore.
Is there a way to save result images for each light group individually denoised?
In a perfect world this will be possible while rendering is still active, or the light group adjustment keeps alive after stopping the render.
Thank you.

Re: Handling of relative refractive indices
Hi, I'm not talking about small tiny surfaces. It's a plastic part that is made in 2 shot process. One shot is a clear polycarbonate and the second shot is a black acrylic... This part is later on illuminated (through the clear element) by few LED In real life the intermediate face of those two volu...

Re: Handling of relative refractive indices
Hi, It does for glass. This means that one could have an light guide effect of a glass tube surrounded by some black acrylic cladding? At least for a very narrow (almost parallel) beam pattern it should work... I'll investigate that a bit... Back to the main topic. Do you think this fresnel behaviou...

Re: Handling of relative refractive indices
Hi, Thanks for answering... Well, the situation described by epilectrolytics is what I meant. So yes, the result is always the same no matter of the volume IOR you are inside. If this is really the case the result is wrong... From my opinion you have to calculate the relative IOR before calculating ...
