The surface appears fine in shaded mode but when switched to rendered mode there are very prominent stretch marks visible please help

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 ?
@scottd… fyi…

The render settings are in that screen shot I show. The key is a high Initial Grid Quad.

Is this an appropriate solution to surface edge quality? (I’m getting that “faceted/torn” look between the edge and the face of the surface.
Increasing the number of Initial Grid Quad is one method to resolve this issue.
Another method is to set a suitably small “Maximum distance edge to surface”. The default value of 0 causes an arbitrary non-zero value to be used which may be too large in some situations.
If you are looking for no seam (torn) look then surfaces need to be joined. The challenge is then that joined surface produce triangular meshes at the edges.
