Messed up normals after OBJ export?

Technical Support Basics & Interface

Hi folks!

Recently I promised a friend to create some props for him to use in Poser.

During experiments I found something strange about Blenders Wavefront OBJ export.

The model I created was made up of five independant meshes. I disabled “double sided” for alll meshes and checked with “draw normals” that they all pointed the right way.

Then I exported the model to OBJ and imported it into Poser.

Some of the meshes had the their normals inverted, so I kind of look “inside” them.

I imported the same OBJ file into Wings, to make sure it wasn’t an error in Poser. The normals were messed as well.

Even a re-import in Blender from the OBJ file showed the same inverted normals on some meshes.

I could probably flip those and export again to fix, but I don’t think it’s the right way.

Anyone got any idea what might be wrong here? I can provide the blend file in case it helps.

Bye!

Have you tried exporting a different mesh? I have been exporting meshes (A.N.T. meshes) as .obj files all day with zero problems.

(this is 2.36 you’re talking about, right?)

I disabled “double sided”

Turn double sided back on
and export.
Then Import into Wings.

Does it work?

Yes, I was using Blender 2.36 and the Wavefront OBJ export Python script that came along with the Windows version.

I’ll try the mentioned hints… once my PC is up again. Looks my CPU got fried :frowning:

I’ll post any news here.

Thanks!

Bye,
