QWe are using QuickDraw 3D and are applying UV Attributes to our geometries so that we can texture-map. There are, however, two sorts of UVs - surface UVs and shading UVs. Which one do we need to set to get the textures to map correctly and what does the other one do?
ACurrently (QuickDraw 3D 1.0.4), only the surface UVs are supported. The shading UVs will be used in a future version to support advanced shading renderers.
