displacement artefacts

[moebius]

hi!

The whole knob is a displacement. (32bit tiff)
Why do I get those sharp artefacts?

This is one of the limitations of Texture Displacement.
To solve, change the mode of the Displacement node from Texture to Vertex Displacement:

thanks a lot! thx for the hint with vector Displacenten, I always thought I need a "colorfull"bitmat like for "normals" for that.

sorry for posting in the wrong forum
