Hi Georgios. thanks for you reply. As you may know The Plane have a Max of 1000 Segments. My Image Displacement Elevation image have a resolution of 9600×9500 Pixels. So I have to add a “Sud Polygon Displacement” Level 2 or 4 Makes no diference. Still Showing the error.
One Interesting thing is: If instead I add a Displacer Deformer the issue is not showing but because of the Limit in the segments the result of the final render is at a very low quality compare with the Map and Sub Polygon Displacement.
