Robot humanoid with skull 3D model

It's the 'Technic Terminator' !! Sadly, although the FBX model opens okay in 3D Paint, it 'exploded' when imported to PoserPro_11.3. Free Autodesk FBX toolkit declared the file was 'corrupted', could not view or explore it. Please check ?? FWIW, the massive OBJ/MTL opened s-l-o-w-l-y but okay in 3DOC and PP, but is un-rigged... == Author responded very promptly. Checked files, confirmed issues, re-worked each format, iteratively repaired FBX, did extensive testing. All good, now !! Thank you. FWIW, import to PoserPro_11.3 at ~1% rather than 100% default. High-resource model, required ~1 GB RAM. Parent parts to 'dummy' character, may be posed with care.
