Mesh fixes (if you install these, you don't need the provisory updates on Nexus; you still need the standard updates): https://drive.google.com/file/d/1GEKAMIzbIYdkWeppLG5mmu3DE6s...
The mod contains new normals to which a new alpha layer has been added to be used as specular. This allows the Oblivion engine to generate reflections. The normals and speculars were AI generated and later manually assembled with GIMP.
The release is functional. Later releases will focus on making sure the normals are appropriate for all of the objects.
