[Bf-committers] bump mapping - white is down & black is up???

[Daniel Salazar - 3Developer.com]

right.. we could come up with a million analogies for one or the other
side. Anyway I've done some investigation and the other mainstream
software I checked all use white for height an black for down. We
could have a fix like the one they did for normal maps

cheers
