Obj Import Render problem

I used a script (obj_io_modif228.py) to Import a demo obj from Pixelogics Z-brush site (http://www.pixolator.com/zbc-bin/ultimatebb.cgi?ubb=get_topic&f=1&t=009275) I was able to import the object and I can view it correctly with the proper UV texture in the openGL windows of Blender.

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.

Any Ideas on what I’m doing wrong?

Thank you,
J

If you enter face selection mode (Fkey), do you see any faces?

Martin

Yes.

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.

Thanks for your response,
J

uhm… if the blend file isn’t too big, maybe you could upload it somewhere and we could have a look.

Martin

I can’t upload it but I could e-mail it to you (I think).

J

I’ve uploaded it if anyone wants to try his hands at getting it to render: http://www.clubinfo.bdeb.qc.ca/~theeth/Temp/PixZTest1.blend

I’ve tried everything I thought would work (in both 2.23 and 2.28a cvs version), but nothing worked :frowning:

Hi jwaggone and theeth

Tough one, but I got a render. You just have to erase the material that’s assigned in the Edit buttons. That’s all…

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.

Thanks, That did it!

I could also fix it by creating a blank mesh and joining the obj mesh with this one.
