Not quite in same league, but I've just been wrangling a couple of budget multi-format 'golf carts' from another site.

Poser, of course, took a serious dislike to the rigged FBX: Not only did the many materials not call the supplied mapped textures, but the cart roofs were skew to carts. My usual trick of zeroing rotations aligned one roof parallel, but that was all.

Time for 'Plan_B': I re-exported the FBX from free Noesis. Now, loading this FBX at default 100% scale prompted Poser to ask me to locate those meaningfully named textures. I also had to manually hide the set's vast sky/backdrop, tint windscreen glass and dial to ~85% transparency...

FWIW, scene complexity crashed my twin GPU cards' superfly render, I had to switch to CPU-only. Networked 'Box' not available as doing a belated Windows' update...
