When I try to render it , however, it is not visible in the scene. Just to try all the buttons I could find, I changed the texture to a halo and I was able to see correctly colored halos at the various vertex points.
The face mode seems to work fine. I checked this because I wanted to see how the UV coors were layed out on the texture that Pixelogic provided.
I also tried pulling a couple vertices around to see if the object was really solid and it seemed like it was. Also, I can see it if I render a specific view window. But I guess that’s because Blender is just using the Open GL drivers that I already know are working.
I had the same problem. I created a plane sphere in Wings with no materials and exported it as an .obj file. I then loaded it in Blender 2.23 using the python script mentioned. When it imported into Blender it looked as if the normals were flipped but it would not render. I added a material and it rendered then I deleted the material and everything was normal.
