Re: CGI tech news box

1) Do you think so? Well, they are highly educated IT university employees, they study physical effects and write their own renderer and its enhancements. They are not artist or color perfection workflow engineers. Well that doesn't make those examples more appealing to me... Anyways. What I think ...

Re: CGI tech news box

I think that it would be cool if someone would make an open source scanning solution and format MDL SDK is open source: https://github.com/NVIDIA/MDL-SDK And it is trivial to integrate in C++ or CUDA (no OpenCL support indeed). It was one of the interesting aspects. Why isn't it widely adopted yet?

Re: CGI tech news box

I think that it would be cool if someone would make an open source scanning solution and format that woul utilize some "AI" networks to build all the complex data from few photos of material under different lighting or something like that... An open source format with easy do do your own scans could...

Re: CGI tech news box

Well, I find application independent physical based materials interesting. Yes, idea is nice... But, it's been out for years unless I'm wrong. So why haven't everybody adopted it to a point where I could go and download or buy 3D models using only or mostly mdl's? Maybe I'm looking in wrong places....

Re: CGI tech news box

Interesting: https://news.developer.nvidia.com/sharing-physically-based-materials-between-renderers-with-mdl/ Oh god... Did you find anyone (professional) actually using this mdl stuff? Why do you find it interesting? It's been around for few years afaik and I never seen anyone using this and I nev...

What is samples per step?
That's the cache update period (path sample count between updates).
well then the "cache update period" or something like "compute each (#pass)" name could be a bit better maybe. But I don't know.

Re: PhotonGI caustic cache re-factoring

I would hide normal angle, might serve little to no purpose so to avoid errors on user side it might be better hidden. (unless Dade or someone else knows of a reason to manipulate this value) What is samples per step? It's "the compute each # pass" value? Or is there something sampled 8x every step?...

Re: PhotonGI caustic cache re-factoring

In my opinion, and I've said this before. Initial radius and reduction is bs and serves absolutely no purpose. Large random initial photon patches will never look good in any case. In real cases you just need to pick lowest radius/blurriness that you can get away with and render that. Those big init...

Re: CGI tech news box

+1 for a good firefly removal, it's a bit of problem to mix denoised and non-denoised result when there are strong fireflies.

Re: Adaptive sampling improvements

One more thing. Can this whole adaptivity be tweaked to prioritize undersampled areas even before noise? look at this image: 03.jpg to me this looks like noise is picked up ok, but there are areas that are not noisy, but more like almost not even sampled/completely black. So I don't know if this mak...
