Re: Vray + Displacement - Creating realistic GRASS???

I have an grass image I want to apply displacement - or bump - but I have no bump/displacement maps. Can I create one from the image? (As I think bump is greyscale of the colour image).
And the displacement map is the same or it is different?

Thanks

normally u can use the same as the bumpmaps...... black doesn't displace. white displaces most if I'm correct

I mean, the env mapping method only works if the camera is placed in the height of human eyes. If you like to render a view from a higher height like from a flying birds view, than it dosn't work.
