@spikeyxxx and everyone else that joined, thanks for all your inputs.
3.3.2 doesn’t work for me at all, i have applied shape keys and multires as well as rebuilt it with the exact same result; none.
i have now tried multires on a sphere, adding all types of wrinkles, bumps, creases etc. in 3.4.1 and it all baked perfectly on all resolutions too.
althought it makes no logical sense, i have now agreed with myself that this mesh is only causing issues, and most likely will remain problematic even if the 3.3.2 worked for me.
i am about to finish the course, and i have learned a lot. this mesh will remain as the course head that has never gone further than that and that’s fine, i will jump onto another one with the knowledge i have now.
it is too time consuming to continue finding a solution for this, spending an hour on smoothing verts is not a solution at all. also the 3.3.2 displacement maps look really bad compared to any other / my newly baked ones.
it is a shame that nobody knows the issue or solution however, and it is really hard to believe that this is a bug since all other items work. it’s even more annoying to me as i wouldn’t call myself a beginner either!
i will keep on checking this thread from time to time as they say ‘hope dies last’
