I'm creating a dune model in blender with cycles and the shadows are kind of messed up. the model is only created from a subdivided plane and then using noise textures. it already has 1.7 million vertices so i don't want to increase the subdivision modifier any more. Do you have any ideas how to make the shadows "softer" without increasing subdivision?

Thanks in advance!

    $\begingroup$ it may be the "terminator effect", you can try to increase the size of your light to fix it. Anyway it will be fixed by an option in the next Blender. $\endgroup$

Using 2.90.1+ version of Blender, in Cycles rendering, you can change the shadow terminator offset:

This is per object, in the object property panel.
