How is this Normal Map created?
Hey guys,
I've a qucik question about this model here:
http://www.behance.net/gallery/Middle-Eastern-Hut/2297086
I know the details have been sculpted in Mudbox, but how has that much detail been added to the brickwork normal? Is it a really clever use of generating displacement maps from the diffuse, then baking normals? But even so, I can't see how that much detail can be achieved? The only other thing I can think of is that it's been sculptured by hand and then a diffuse created based on it, but that must be insanely difficult!?
Thanks

Though it's generally better to go with 1024s and detail textures, because those huge bitmaps mean a huge memory cost, in most game engines.

@Wahlgren - I am using a detail normal map to get those fine details. It's just a simple noise pattern that just tiles.
All of the larger details were sculpted and baked down using xNormal.
@tolls - let me know if you need more info.
