BoB lighting capabilities. OpenGL and Direct X question. HDR/Caustics supported?

It's quite noticeable on terrain if you set a late afternoon time, so the sun is low. It's not necessary to use a separate height map...you can bump-map a texture using itself as the bump-map, interpreting light/dark transitions in the texture as changes in height or angle. Or am I using wrong terminology?

I may have to revise my comment about caustics...I was recently testing some maps for SEOW, and noticed a line about caustics flash by in the console as the mission was loading, so perhaps there is already some support for it in the existing game. Perhaps to do with water in shallow areas?

Well, FS9 or FSX is not really a good example for realistic water with DX.

Might be, but I haven't seen an example of bump mapping that doesn't use a height map. You might be thinking of Parallax mapping.
