Altitude sensitive mapping of displaced surfaces
Posted: Fri Aug 03, 2007 6:01 pm
As i guess NL aren't yet finished wrapping up displacement i'll take the chance to toss in this request. 
I would like to be able to map displaced surfaces differently depending on their height over the surface they're displacing. Meaning that in the range of 0-25 pixels you have map X, and in the range of 25-75 you have map Y, and finally in the range of 75-100 pixels you have map Z.
With this method you could map for instance a displaced building or a mountain if you want. Or you could use it to add dirt to your objects.
This can also be taken a step further by adding support for slope senstive mapping so that materials map themselves differently depending what the angle and direction of a surface is. This could come in very handy for alot of types of surfaces.
Btw NL, make sure there's support for negative displacement values and not just base it on using inverted maps.
