I was quite surprised about the performance of the BumpOffset-Node and so far got some quite nice-looking gravel and sand-materials for my landscape.
However, the lack of self-shadowing is obvious This would improve the materials a lot as the map is set in late afternoon-lighting with incident sun light at low angles.
I tried this approach that worked quite well in UDK3 but now does not seem to work anymore. It tells me that the “LightVector”-Node can only be used in deffered materials or decals?
Any hints on that?
