This is mainly for you folks who work at Crytek but anyone in the know is encouraged to reply. I've been examining the normal maps created for the vegetation in Crysis, I was wondering how they went about creating them.
Did they create a gray scale displacement map in photoshop with a trusty tablet or something completely different? I'm leaning toward the displacement map option but I've yet to try it with my diffuse textures.
Any tips are appreciated!
