So when I hit apply to base on the Multires modifier on the the Belt and then go and check the mesh on edit mode I notice that it’s size is a lot bigger. This doesn’t happen when I do the same on the wrist shackle.
I understand the concept behind apply base and googling I have found other people with a similar bug in which the base mesh “inflates” after Applying base. Well… If I find a solution I will let you know.
