Also i see that big first sample take too much time to disappear. can we reduce this latency ?
There is parameter for that: rtpathcpu.zoomphase.weight

Re: PhotonGI cache

I might be missinterpreting stuff here, but to me it looks like cache looks at first hit ok, then it somehow got overwriten by weaker entries but then at some places bounces with proper power, might also be source of some leaks.... no? It is because the geometry is bad: check the roof, it is a sing...

Re: PhotonGI cache

What do you mean by different values? I though that photongi doesn't even use clamping... About path depth... if too low values like 4 and lower are a bit low, and above 8 seem to not make too big diffrence... maybe we should simply have hardcoded 8 or 16 and get rid of it. Especially if it can bre...

Re: PhotonGI cache

What puzzle me is that I'm quite convinced now that the problem is not in PhotonGI at all but in backward Vs.forward ray tracing results (aka Path tracing Vs. Light tracing). PhotonGI incidentally just does light tracing. This is a rendering with PATHCPU (no PGI involved): path.jpg And this with LI...

Re: Can I save the progress of rendering in order to continue it in the future?

Very nice to receive detailed help. Could you explain something else? Is rendering by layers technically capable of reducing the amount of memory used for each layer that is currently being rendered? Or in any case, the program has to read the entire amount of information, for example, to get a sha...

Re: Can I save the progress of rendering in order to continue it in the future?

It's fine. Thank. After me I have another question. I have two video cards on a computer, 1 and 2, 11 GB on one, 4 GB on the other. The question is - if my final scene weighs more than 4GB, will the render just not happen, or what? Maybe I somehow misunderstand this process. If you start the render...

Re: Can I save the progress of rendering in order to continue it in the future?

Can I save the progress of rendering in order to continue it in the future? Or is such a function planned for at least a year? It is already possible but I think it is not supported directly by BlendLuxCore: you have to export the scene and than you have to use LuxCoreUI (included in stand alone ve...

Re: Some tests to understand Lux

Thanks you! Wow .. 66 pages! I'll have to take some days off! :D It is mostly development related stuff so it may be a bit confusing. As Sharlybg wrote, the best tool is the "debug" view. It is a direct view of the cache content and, with a bit of experience, it is easy to evaluate, if the radius i...
