Thanks for the response, but I dont think its an issue, rather a weird behavior
The behavior of the shading direction is not the only thing that is strange. When using transparent objects (with another object that recives transpatent shadows), those objects do not get any shadow at all.
That behavior makes variance shadows almost impossible to use.
Usually almost every object in the enviroment of a game use alpha for details for example leafes on trees and so on, not to speak of other effects.
Please both problems needs to be fixed!
