Why is shadow going through a part of a wall?
On the screenshot is one of the corners of my room, which is built in Blender and imported as a .blend file. The top of all of the walls throughout the entire room have a little light penetrating through from the top, as shown on this bit, as if there was a gap between the ceiling and the wall, but there isn't one.
I've even tried making the ceiling unnecessarily larger, so that it goes over the walls, assuming that the shadow might just be a little off in calculation. But there was still the same leftover light on the walls. Why does this happen and how do i eliminate it?
What sort of lighting do you have? Directional/Point? Realtime/Baked? Deferred/Forward rendering?
It happens both with directional and point light, it's realtime, i don't know about deferred/forward... Inspired by your comment to click around the settings, i have found that increasing bias increases exactly this behavior. However, when i set it to 0, some light still passes through (although less than before; by default it was .5). It's better now, but still not completely gone.
You can prevent this by modeling the walls and ceiling with thickness, so they have two sides.
Well it kinda doesn't exactly work, with smaller thicknesses it still happens, and the fact that it's two sided doesn't seem to matter. But it works as a side-effect when i exaggerate with the thickness.
