By the way, Sharlybg, can you start the viewport render in the Nakagin scene?
Because on my computers, it crashes on both Linux and Windows.
But only this scene, and only since a few days. I think some recent change broke the RT PATH CPU engine. Final render works fine, as well as Bidir in viewport.

Yes can but only now. Before that all my old luxcore project wann't render because of a "empty band" node issue. each time i start to try a given old luxcore project all Band node were reset to empty band in all shader so i'd to redo recheck each single one to make it work again .

Was thinking about a way to talk about it but with a lighter 3D scene but can't find something like that.
So check the dark shader of the black lamp on the wall (look for the band node).

[Sharlybg]

It may be a factor only if you are using caustic cache (not if it was an indirect cache only rendering).

Don't use caustic cache here. only indirect as you say.

Still having a problem with this......

Thanks

The scene (attached) crashes every time with PGI on, and any scene I create with a MIX material like this, also crashes.

[Sharlybg]

By the way we still miss a clay/custom override shader feature !

No, it's in the render layer settings:

Woahou how i miss something like that. Thank for being faster than my thougs

I think this problem was already fixed, with the latest sources I only get

PhotonGI WARNING: nothing is visible and/or cache enabled.

as warning.

I should have fixed this problem.

Nothing about the dark render ? Dade can you try nakagin scene on your side for brightness comparison ?
