Importing OBJ files in blender gives positions that don't (textually) match the .obj
file.
That is to say, a vertex that has position (1,2,3)
is imported with coordinates (1,-3,2)
(I think, this is what I want to check).
As far as I can tell, this transform the importer applies is
(x,y,z) -> (x,-z, y)
. Is this correct?
