Hey did anyone manage to recreate that additive look for light streaks?

In Mantra Ive achieved that by lowering the opacity and cranking up the emission (Ce). So overlapping geometry adds up and resulting in overexposed areas

I am trying my luck with mtlxsurface_unlit but it looks like emission is not multiplied by opacity beforehand, which results in very even emission, and I am not getting that overexposed look

minutes later . . .
nevermind, its working as expected. the emission color value in it self needs to be overexposed a bit work

leave opacity at 1, and set transmission to 1. Emission should not ever be multiplied by opacity, but unfortunately it is with the standard surface, and unlit surface. The workaround is to use transmission, which the unlit shader has.

thank you for the file!
