TGorillaSplatMapMaterial

A SplatMap material renders maximum 4 textures overlayed depending on the supplied splatmap texture which is used as control element.

To use more than 4 overlayed textures, please apply mulitple TGorillaSplatMapMaterialSource instances to a TGorillaLayeredMaterialSource.

Of course the each splatmap should have the valid transparency settings, otherwise layered material shader would overwrite pixels.

public UseBlackAsTransparent : Boolean
Enable black color as transparent areas. This is useful for multiple splatmaps in a layered materials.
