Can I exclude a light (or Emission node) from PhotonGI caustics?
The Material Output's Use PhotonGI Cache checkbox doesn't seem to work for this.

Look, I respect, that you are a professional, who wants fast results due to productivity. Why can't you accept, that there are other people with other viewpoints? Simplistically, you want LuxCore to do what Cycles can do, but a little faster and/or more conveniently. For my part, I hope you will get...

I wonder what is bigger problem od bidir than the fact that you would have to spend ages to get a single frame that is pretty much indifferent to pathtracing done on gpu within minutes... The answer was there, but you elegantly left it off from the quote: ;) The problem with BiDir is not so much la...

I think the best all around solution would be focus on pathOcl+photonGI + some fast way to do caustics so that bidir becomes obsolete. I understand, that you prefer speed over accuracy, but please take into consideration, that many people uses LuxCore for optical study and experimenting, so I hope ...

I just realized, that maybe this sounded a little offensive. I only wanted to ask what to expect in the future.

Do you think Path+PhotonGI caustics will ever be able to fully substitute BiDir? (glossy, volumes, etc.)

Yes, I could add also glossy nearly-specular materials to the set of materials supported by the cache.

That would be very welcome, for glossy, metal and the upcoming principled materials.

Here you go:

And here is the Blender file:

Expose uvmapping3d (available in the 3D mapping node, can be used to map procedural 3D textures with a UV mapping)

I could finally test it and I love it!

Here I used only procedural textures, and - as expected - the patterns nicely follow the shape of the leaves:

Thank you!
