Displacement

[d_ray]

i am trying to use this texture for displacement. middle grey is 50%.50% grey is no displacement. brighter then grey is positive displacement and darker is negative displacement. its 8bit.

the problem i have in vray is that the middle grey in vray displaces. . so it looks at the middle grey and thinks its positive. i tryed to use the shift but it didnt help. i also tryed to set the texture to gamma 1 but no luck

anyone have the same problem?

Re: Displacement

first render is without displacement.
second render is with displacement. you see that the plane got up because of the displ so that the red plan is gone
in the third render i used negative shift. -0.5

Re: Displacement

Check this issue: https://github.com/bdancer/vb25/issues/47 I've posted some suggestions there until I make some code additions. I just find that shift works slightly different in 1.5 and 2.0 vray and wrote an email to support.
