This looks to be a meshing issue. Go to File-Properties-Document Properties-Mesh and try “Smooth & Slower” to start. If you want to get more finely tuned, go to custom - I personally like setting the Maximum Aspect Ratio to something like 5 and the feeding a value of around 0.001 for “Maximum Distance, edge to surface” but that last one really depends on the size of your model.
I used the Minimum initial Grid quad setting to get it to behave. This is my normal go to setting when needing a better ordered render mesh:
Thanks mate it helped
Hey brother could you please help by sharing your rendering settings ?
The render settings are in that screen shot I show. The key is a high Initial Grid Quad.
