Yes, sory. Now i see. It's really strange.
It's getting closer to bidir when i switch glass in architectural mode. But in this case we can not control rougtness.

Try to increase diffuse light path value. I don't know why, but changing diffuse light path value also influences on volume.

Yes, maybe this is problem with normals. But i don't understand why multiscatter ggx solves this problem.

Hello, I have a problem with the metal in luxcore.
How can I get rid of these dark edges?
I had the same problem in Cycles, but when I switched to multiscatter ggx in principled bsdf, the problem just gone.
I don't see the multiscatter ggx option in luxcore.
