Is there a free tool I can use to view and inspect FBX assets? I've got a bunch of FBX files and I'd like to look at the mesh and textures and preview the animations.
Found it! The FBX Converter can be downloaded from the FBX Plug-Ins, Converter, and QuickTime Viewer Downloads page. One opened there's an "Add FBX Viewer" button which can display FBX contents and animations.
Down the page is a thing called
FBX 2013.3 Plug-in for QuickTime
I think this will allow you to open FBX files in Quicktime.
