At any rate, I have seen some other posts here and elsewhere regarding issues importing MotionBuilder FBX into Maya, though none match exactly what it happening for me.
I have the latest FBX plugin for Maya, and I can export to FBX perfectly fine. I can likewise re-import such FBX files into Maya. However, when I open the FBX in MotionBuilder and save it from there (whether or not I have animated/plotted, whether binary or ASCII FBX, whether I leave all contents or just strip the file down to animated bones, etc.), Maya does not import it. When I import in Maya, the FBX dialog sometimes does not appear whatsoever, and sometimes it does, I select the take I want to import, and the dialog tells me it is importing the take but it just does nothing. The program continues to respond as normal but the import dialog just sits in place. Sometimes there is no error message at all, and sometimes I get this in the Script Editor output:
file -i "D:/test.fbx";
// Error: print "C:/Program Files/Autodesk/Maya8.5" ====; //
// Error: Line 1.45: Syntax error //
Does anyone have any suggestions for anything obvious I may be missing? I appreciate any assistance!
