My object only get light to one side, i showed on screen shoots, i tryied making two-sided and one-sided, any other ideas what can solve it?

If the mesh is a plane, it could well do this. It’s always a good idea to have ‘thickness’ if you want to exclude light

[PePsiCoLniyVeYp]

It is cube mesh, but thin

[ClockworkOcean]

Is it a point light? Is it very close to the mesh?

[PePsiCoLniyVeYp]

It is rectangle light, it is pretty far

[ClockworkOcean]

Well, it’s hard to tell from here. I guess if you replace the material with something very simple, and it’s ok, then it’s the material?..

[PePsiCoLniyVeYp]

Did not try, but i will, not at home now

Made it all white, still one side is black
