I have been exporting OBJ files of designs to load into Google Poly for sharing models with AR, since most of my students don't have Ipads. The problem I run into is that the OBJ file models are rotated 90 degrees forwards (ie face down) and the MTL file contains a line that reads Ilum 0.0, which Google Poly does not like at all. When I remove that line from the MTL file, and rotate the models onto their backs, they upload beautifully in Google Poly. Any chance these things could be changed so I didn't have to do it for every model?
