Displace vertices based on their normal and a texture lookup for the amount.
Displace Param Description
Map
Texture to control the displacement, uv coords for a vertex govern the lookup pos. Texture must be readable.
Amount
Amount to displace vertex which is modulated by the texture lookup.
Offset
UV offset, use for scrolling.
Scale
Scale uv coords.
Channel
Channel of the texture to use for the displacement.
Cent Lum
Usually the displacement is in the range of 0 to 1 so everything is moved in one direction, sometimes you may want to move things up and down for example if so check this, then values less than the Cent Val will move vertices one way and values above will move it in the opposite direction.
Cent Val
Change this to bias the displacement.
Decay
Falloff value for the effect from the origin of the mesh (remember you can move this using the Offset value in common params) this will diminish the effect based on distance.
