When there is a light source close to a wall (a fire stick for example), you can see the light shining through the other side of the wall on the ground and on wall corners. I know Doom wasn't meant to have dynamic lights from the beginning, but can this problem be fixed?

Not without a stencil shadow buffer or some complex trickery. But this is GZDoom, not Doom 3.

IDEA: Edge has pretty sick "shadows". I'm sure you've seen them, Graf. Perhaps the same principle could be applied to dynamic lights with stenciling or something?

This is a non-trivial problem that cannot be solved without considerable alterations of how the engine works. And that's something I won't do.

Many pre-doom3 generation engines also show this problem.

It's not surprising. Even half Life and it's mods does this. When people fire guns, the lights go right through the walls.

... and they even light surfaces facing away from the light source although excluding them is a trivial calculation so it's amazing it wasn't done.
