One more question: According to the "Advances features" pages, "Using light groups, one can interactively adjust the color temperature of any light source during rendering without losing the rendered samples." Is this still supported when NOT using photonGI? I've skimmed over the...

I have split some posts into a new thread: https://forums.luxcorerender.org/viewtopic.php?f=10&t=1197#p14282 Thanks! Now a slight off-topic question (not directly related to VRay): since PhontoGI doesn't support radiance groups, can I do two renders without loading the scene twice? Like this: -...

It more a matter of memory usage: you need a separate cache for each light group (it is a bit expansive). I also wonder if it is worth doing because rendering time with the cache are really low. Light groups were development many years ago when rendering time was measured more in days than minutes....

Thanks, B.Y.O.B and Dade. Note: PhotonGI doesn't support radiance groups at the moment. ah... Is supporting radiance groups in PhotonGI officially planed? How difficult is it? No good way to do it? Or it can be done, but there may be some penalty/restrictions? Or nothing really difficult, but needs ...

It's not possible in the LuxCore imagepipeline, but you can use numpy or an external commandline image-editing program, e.g. imagemagick. Ok! Thanks. And what about the "radiance group" part? Is it possible to get AOVs for multiple radiance groups in a single render? Or maybe it's not pos...

I'm interested in my features mentioned above, but there are two most important ones that might be a deal-breaker for me: * multiple uv maps (Most of our normal-mapped meshes have two uv sets, one is generated during normalmap baking) * AO/dirt shader (I mean raytraced texture like VRay's VRayDirt, ...

If you use a linear tonemapper, the results are linear and you can just add them together. I think your idea is even better than mine: desaturate the noisy indirect light AOV a bit, then add the noisy AOVs together, then denoise - this might work much better than denoising the individual AOVs and t...

You should look into filmic tonemapping. I'm no expert on this, but I read that filmic reduces saturation in the bright parts of an image which also means reduced color bleeding. Filmic is available through Blender. yeah... I'm aware of filmic tonemapping. We use it in real-time renderings... We'll...

You can create any number of imagepipelines with any AOV as input. However, I do not know how good OIDN works with AOVs other than the combined image. Since it's a trained neural network, it's hard to tell. Thanks! But are imagepipelines "linear"? I mean, is it possible to "merge&quo...

I mean "direct light sampling" = "Sampling the light source" and "Eye path sampling" = "Sampling the BRDF". Oh! Now I fully understand. Thanks for your help & patience. Now the next question: some of our customers are quite "allergic" to color b...
