When I want to convert a blend file created with 2.79 blender using space shift editor 1.2.0 an exception arise with a strange message “Unknown blend type 16”.

I tried to test the converting of the simple cube from that blender version and it’s working. So i tried to convert that blend file to Wavefront and tried to convert that obj file and another exception arise.

Try to use xbuf/GLTF as importer as blender importer is not feature complete and it seems that obj also has it’s flaws.

ogre.xml also works pretty well.

Thanks guys. I faced some problems in using xbuf. So, I found that the problem was in a small part of the model (sidewalk) when I try to give the texture a color (yellow and black).

1st error looks like blender garbage getting in the way, a blender file that has had lots done to it easily accumulates ‘garbage’ : unused references and geometries.

2nd error looks like a problem with the .mtl file perhaps ? often the links blender has to files are not properly translated to the material file of the obj… to be safe, I never export materials with obj’s and delete any material files created by accident.
