Hi Visual Designs,
There is no way that I’m aware of to reduce this type of affect with the geometry there without using temporal AA to reduce the aliasing or for the best result this is a good case where Normal Maps would be a good option.
I’ve got three images below showing the result you can get using a normal map vs the modeled geometry with the aliasing.
Left is the normal map with the Right the modeled geometry
Thank you!
