I created a pattern in blender and rendered it as a 32bit openexr to use it on a model in an other scene. There I changed the feature set to experimental and the material to displacement only and plugged the map into the displacement slot. I use adaptive subdivision and it worked so far. But a closer look offered that there are some issues in the rendering with weird cuts in the shading. Changing the value of the dicing scale won't fix that. As you can see with solid shading everything is absolutely smooth. What is the problem?
