They are the fade of the shadowMap, for Lod Shadow display. 0-1 values. NB: if DistanceFade==1 or TemporalOutScreenFade==1, then the ShadowMap Texture is released. Final Fade is the max of the 3.

This value represent the fade time we don't know what to do with TemporalInScreenFade because the shadowMap is not visible or frustum-clipped. Once the shadowMap will be visible again, This will be add/removed (according to TemporalInScreenFade rules) to the TemporalInScreenFade. NB: by default the value is 1 so the initial state is correct when you enable cast shadowMap!

Computed at shadow casting time. The matrix used to cast the Shadow. It is actualy a World ProjectionMatrix, but is only local to the Position of the Model (not rotation/scale). Hence receiver have to add the position of the caster model to this matrix to get true World. The usage of this matrix is for UV projection: XYZ= WorldProjectionMatrix * UVW. NB: Vj (ie for W) is mapped such that Vp means NearClip of the shadow and Vp+Vj means FarClip of the shadow
