Displacement = black rendering

[louis.cho]

HI

I am trying to make water for a ship render but I can't use displacement. Each time I put a map (noise, bitmap or whatever) in the displacement slot I get a black render. I use Vray 01.05.29. CAn someone know what it's going?

Re: Displacement = black rendering

how big is the area your trying to diplace?
if you have a massive area, you maybe asking too much of your computer.
firstly make a much smaller polygon say 2m x 2m, apply the texture and group the geometry in order for disp' to work, and render. if it renders fine then its obv your area previously is too large. breaking the area down into separate groups like tiles on a floor should fix this.
if the same problem occurs.... i have no ideas unless you could provide some more info
