Hey guys!
I'm getting a weird issue here that has me scratching my head.
So essentially I'm converting a large building with around 30 geosets from OBJ to WMO using MirrorMachine. I do this pretty often and very rarely have any unusual issues. However, in the case of this one, upon being converted half of the model is invisible / the normals seem screwed up on some of the meshes that aren't rendered invisible. I've retraced my steps carefully and:
The textures are all fine and correctly assigned.
The object looks totally normal in Blender, if a bit messy.
The export settings in Blender are correct.
The conversion settings in MirrorMachine are correct.
So I really can't think what would be wrong. There seem to be a few duplicate materials in the .mtl file for some reason, but I don't think that'd cause an issue. I've attached a screenshot below (please ignore the lack of textures; textures work fine, I just didn't bother assigning them whilst troubleshooting):
Thanks in advance for any ideas.
