Importing CAD models into Blender. SolidWorks -> Rhino -> FBX -> Blender. Works fine for rendering in Cycles.
But on export to .html, I get invisible patches in the model, due to the normals being flipped in that location.
Flip normals doesn't work. Make normals consistent doesn't work.
Even Shift+G (select similar normal) and then flip those ones doesn't work.
Seems to be watertight. How can we just make it point the normals away from the interior of the object?
