#DooM 2.5D #bumpmap textures

Same concept of XY displacement, but X displacement needs to be inverted when a surface is aligned along Z to give the illusion of the light comming from the observer. Completely unrealistic lighting tricks.

I don't feel like I can make any more dweets with so many good ones like this roaming around.
