This normally isn't an issue as most exporters write a duplicate of diffuse to ambient tinting anyways. The problem is likely a well over 20 year old incompatibility issue in the format's definition of diffuse and ambient term tinting between the Alias/Wavefront Specification and Autodesk's implementation in 3D Studio Max that Apple seems to have sided with the incorrect implementation in Max. but I am mostly sure that is what your problem is and this fixed it. Haven't tested it on the mac since I do not use mac. (I wish I was joking) I am looking for a compromise to this problem. As a result countless packages intentionally incorrectly swap ambient and diffuse. I've investigated this issue, it stems from Autodesk messing up their loading of diffuse from MTL files in Max and Maya. I don't think it would be correct for the exporter to just add the diffuse texture as ambient reflectivity. That is rather strange handling of the file format by the previewer. Thanks for investigating this and identifying the issue. I have no idea why so I didn't touch it but now it seems that has to go as well. The current version of Blender's Obj exporter actually writes a mangled metalness value. I expect that map_Ka is currently ignored during import and thus can't be exported properly.Ĭorrect for import but for export its actually worse.
Autodesk memento unable to read obj textures Patch#
The patch hasn't been submitted yet though. According to astrand135 on Twitter they are working on an updated mtl exporter.
