In Unreal Engine 3 you can go to Lightmass-> Light Source Angle and change the value to make shadows “blurrier” (affect penumbra size). Editing this will not force you to recompile the level’s lighting.
In Unreal Engine 4 you do the same, and the level’s lighting will need to be recompiled and no effect is visible upon changing the parameter (tried increasing from 0.4 to 4).
I cannot find anyone else writing about this which makes me wonder if I’m doing something wrong… (I’m using a Stationary light).
In UE3 we had a ‘Self shadow only’ option available… is their any way to do that in UE4? (It doesn’t appear as a lighting option for static meshes).
