Sorry, yet another rant about FBX import. Yes, when the FBX is correctly rigged, with a complete hierarchy, it works like it says on the tin.

Of course, to reach that stage, you may have to do a 'binary chop' to find a usable import scaling. Default is 100%, but I've had them range from ~0.5% to ~3500%, with several I never did find... Please, like OBJ import, may we have a 'scale to figure' option ??

Then you discover eg the body is welded as a solid mannequin. Posing requires heroic surgery & re-rigging, both currently beyond my wits.

Worse, body, clothes and accessories may import as a flock of components in loose formation. Really requires re-rigging, but 'Plan_B' is to use hierarchy display to mass-parent them to a low-poly place-holder such as Les Bentley's free 'MinFig' or Anthony Appleyard's free 'Dummy',

(Latter may need origin re-setting, then saving to library as eg 'Dummy000' prior to parenting. Such re-setting was trivial in P4, but P11 makes it hard. With nothing apparent in P11 PDF manual search or index...)

Thus parented, you can easily pivot FBX from typical horizontal posture, scale the last +/- 25 % from your best-guess, 'At Least It Is On-Screen' import scaling. Now, you notice several parts are missing. A further search finds eg face and hair went astray at import. Gotta back-track. In fact, usually easiest to delete and re-import, now with a better-guess scaling....

Then, how do you persuade your imported FBX to use an associated texture directory ? When you open FBX in eg Windows' 3D Paint, it may prompt for such. P11 either gets it mostly-right automatically, or totally muddles the materials. No obvious way to 'browse' to the set, and a real pain to manually import umpteen textures via material room. Which usually requires me to have free Autodesk Toolkit's 'FBX Explorer' open, too, as there's no obvious equivalent of an OBJ's MTL look-up list...
