Displacement artifacts

[mdharrington]

I am getting straight line artifacts in my displacements....which I assume are from polygon edges in the displaced geometry, seeing as they don't move with the displacement texture, but they do move with the geometry

It looks as if the displacement does not go across polygon lines perfectly.

In testing however, subpatching the object removes the artifact....so not sure if this is UV related

these lines also appear in the alpha channel

Is smoothing on? Turn it on if not.
Do you have a bump or normal map applied as well? Try disabling them.

smoothing did the trick .....as well as subpatching

thanks
