@lacilaci: You should elaborate a bit. Click "Clone or Download", then download zip. You now have all the Python parts of the addon, you still need the binary parts, so download the LuxCore daily build from https://github.com/LuxCoreRender/LuxCore/releases/tag/latest and copy all files li...

Did you try with one of the cameras from your "first steps" project? For example the sky should be detected as noise-free immediately and no longer sampled. From the scene you posted in this thread I agree that there are areas where the human brain sees the noise distribution a lot differ...

Thanks, seems to be working fine now.

How to update ?

Ok, let's try something different... I want to render, go into settings and see adaptivity, read the tooltip and it says that higher values focus on more noisy areas. So I enable it and get what's in attachment. (default noise threshold and 64warmup and 64test step samples, 60 sec rendering giving ...

So how's the CPU usage for people using windows and beta1 with opencl? I'm still getting only 15-20% on cpu when rendering with opencl(alphav4 goes to 100%) It is a bug in BlendLuxCore, it is always telling LuxCore to use 0 CPU rendering threads :!: I have fixed this bug. Thanks, seems to be workin...

The problem seems to be triggered by an interaction of different level of noise cause by different DLSC cache entries and a very very very small clamping value. It is a quite strange interaction but it looks like it is cause only by the variance clamping value you are using. You are using clamp val...

Maybe if the whole adaptivity could be weighted to focus on darker areas..? Is this unreasonable thinking?

well, if we look at original 32bit output values you probably get more noise in high luminance values. But as I look at tonemapped image after filmic tonemapping applied I don't see much noise in bright areas but a lot in darker ones. Convergence test is done in HDR, well before running the image p...

It seems that the sampler uses the convergence value as a metric to know which pixels should be more sampled than the other. How exactly this convergence is calculated for a pixel and why this might undersample the darker areas is a bit beyond me. It is difference between pixel luminance values at ...
