Following (and building upon) Kent Trammell’s tutorial at CG Cookie.
Follow along with my progress in the Sketchfab forum.
Baked AO using xNormal from high-poly to low-poly for each individual component and combined with a proximity bake from Blender that baked the shadowing between all neighboring low-poly meshes.
WIP upload #3.
See upload #1 (low poly mesh)
See upload #2 (UVs & baked normals)
