It's not helpful having assets that can't be tested within 3D packages or converters :/
This horse is one of many demo assets from Truespace (100% free), from:
https://united3dartists.com/downloads.htmlIt came from: "trueSpace7.61 workspace only"
I tried using assimp and the 2013 autodesk FBX/COLLADA converter to get a working .dae file, but surprisingly TrueSpace7.61 Beta 8 Standalone work the best for me, ie both textures and animation work
It didn't create the .material.xml file but the rest worked fine
Note: textures don't get exported, you have to export textures via a different export, I used .x it worked fine.
I can export more if required, there's a few there!
