ProBuilder meshes show weird bright lines within meshes from outside light sources

The title says it all and i got a screenshot attached. How do i fix this? It’s the same with realtime and baked lights. Unity 2019, newest probuilder-package.

So it’s been a few days. Am i the only one with this problem?

Hi! The problem is actually a lighting thing - any time you have a Directional Light shining against a backface (invisible side of a mesh), it will “leak” through at the edges. Try with an inverted cube from Blender/Max/etc, you’ll find the same thing, unfortunately.

The workaround is to use “light blockers” (meshes facing the light, with “shadows only” enabled), or adjust the light’s Bias properties:

Ah, thank you! Thats good to know.
