Sandbag parallaxing...

I've been mucking about with my sandbag textures in UDK to see how it works using Parrallax mapping (or Bump offsetting, there's so many different names for it floating around out there :s).

Basically it uses a height map to give it more depth (which I rendered out using Xnormal) and the results look OK. I don't think this does so well up close but at a distance, like the top image, it works very convincingly.

I think for the walls that you get up close to you just need to put geometry in there...
