I recently rigged and animated a model for my project, but when I tried to export it I got this error:
One or more objects in the scene has local axes that are not perpendicular to each other (non-orthogonal).
The FBX plug-in only supports orthogonal (or perpendicular) axes and will not correctly import or export any transformations that involve non-perpendicular local axes.
This can create an inaccurate appearance with the affected objects:
All those bones belong to the hands of my character. How can I fix it? Many thanks.
