Import OBJ Textures Wierd


(Ryan) #1

So when I import OBJ’s that have been output from other software, say Maya or 3ds Max I get odd results. I get some objects that come in with black textures. Even though in the texture menu they look normal and have the same textures as the other objects. I thought this maybe was a direction problem with normals but when I use the ‘dir’ command they show as being correct. Is there something I am missing?

Black sounds like maybe there are no texture coordinates on the objects but that seems unlikely- can you send us one of the OBJ & textures?

thanks,

It’s for a project, so where do I send to you / Mcneel directly.

Hi Ryan - please send to tech@mcneel.com, to my (Pascal) attention. If the file is very large, zip and upload here

thanks,

Great thanks Pascal,
I appreciate the insight. File sent.

Hi Ryan - try RebuildMeshNormals on the black objects.

And it was that easy. Thanks Pascal, I feel pretty dumb. I’ve had this problem for 6 months and 20 jobs. Just couldn’t figure it out.

Well, it’s hardly obvious - I guess the only thing that might be dumb is not asking 5-3/4 months ago!

Haha! Yeah that I just realised I spelled weird wrong in the subject!
