So it’s about GPU Lightmass, it doesn’t count that checkbox in static meshes under materials for disabling shadows. So I can’t get light pass through the glass as much as I can’t put Point light in emissive lightbulb mesh. The shadow wich can not be disabled eats all the light. Cast shadow as masked not helping, cast raytracing shadows niether. The only way I can do it by disabling all the mesh shadow, wich is pain in the ■■■ because of dividing meshes. Standart lighbacking counts this checkboxes, but it is too slow and result look much more different from 4.25 version. So the question is - are there any workarounds for disabling those shadows? That should realy be in bug reports. By the way compressed lightmaps are full of unwanted color bleeds, and two sided materials are black…
