I know that the hip bones can be reversed when importing MakeHuman files to Blender, but I haven't had that problem. I can't find any information about my issue on the internet at all. I've used MakeHuman and Blender for months without any problems, but when I reinstalled Ubuntu and opened a file created in my previous installation, all the facial bones of MakeHuman rigs are reversed. Ubuntu and Blender are the same versions as before. I only reinstalled Ubuntu so that I could use a different hard drive. I just copied Blender from one disk to the other and opened an old blend file in the new installation. This is what it looked like:
When I tab into Edit mode, the bones snap back to normal. This is what it looks like:
The rig in these pictures was not exported from MakeHuman in my new installation. It was saved before I reinstalled Ubuntu. But I have also exported MakeHuman rigs in the new installation, and the results are the same. I appreciate any help you can offer. Thank you.
