I’ve posted my question in the answer hub here https://answers.unrealengine.com/que…ty-volume.html
But just in case, I’ve decided to ask on forums too.
So, my issues is - Volumetric Lightmap Density Volume, instead of concentrating samples in a specified area, does the opposite - it scatters samples everywhere randomly, and not where they are supposed to be. More so, it leaves the area withing its bounds empty, with no samples at all!
Because of that, I can’t illuminate my movable objects properly, unless I set Volumeteric Lightmap Detail Cell Size to something stupid like 20.
