Hey guys, i've come across an issue in Max 2022. I had to re-import a mesh of mine(made in MAX) back into 3DS. I noticed whenever I rotate the mesh at a SUB-Object level, some of the faces turn black. It appears though the re-imported mesh has the normals 'locked' and I found a solution by using the "Edit Normals" modifier, selecting all the Normals and hitting 'Reset'.
This has never happened before and I have re-imported meshes and altered them many times before. Is there a setting that I have selected on Import that locks the normals? How do I prevent this from happening? I have attached a picture of the occurrence, you can see the magazine turns black when I rotate it. When I rotate the entire mesh at the Object-level, it seems fine. Thanks in advance.
