Courier import - bone indices out of range
Hello, i'm pretty new to 3d modeling and animating (a few months of experience), and i created a courier and animated it (animation files are using reference to original rig). I exported the files to .fbx (baked animations and export constraints) and when i tried to import it, i got this error in the screenshot below. Any ideas what might cause it? I tried googling for what exactly "bone indexes" are but couldn't find anything, so i just cant figure out where the problem is. And why is it saying that it is skinned to an unmapped bone? Any help would be really appreciated. Thanks in advance
