and skilled modders can create bump map manually (as variant withoit Hi-Low poly) ...
using Photoshop and Emboss filter ... you can create two images with different corners (one of variants!!! ... differ. = 100° (80° ... 100°))
and other parametres of the filter and then copy these two images into Red and Blue channels or in others ...
