The title is not very clear , so I add a screenshot
As you can see , there are weird stains where you can see high density edges on the mesh (Yeah I know , it's bad but if I dont do so , the mesh will spherize in a way I dont want when i'll subdivide in Zbrush).
I have almost finished my graduation project (high school art course) but this problem stays and I tried during 3 hours to make something which works without achieved it (I use Cage , but I loose details and the normal map looks a little bit random)
thank you for helping me guys ! :)
