FBX Import on 2.75a giving me errors

Support Technical Support

I made these objects in Blender to go into our game about a year ago and I don’t know where the originals are which shouldn’t be an issue because I have the FBX… or at least I thought so. I’m getting an error when I try to import the FBX. I would appreciate any help.

The FBX version is 7.3 if that helps at all.

The lack of FBX support is forcing me to go back to Maya! This sucks guys. :frowning:

Any info on this error? I am running into the same problem exporting animations. It only effects some of them.

Sorry, my issue is on export.

Mine was never resolved. I had to go back and work in Maya even though the original object was made in Blender. :frowning:

I’m sorry to hear that. I always talk Blender up because it is a great open source software.

I found the issue was that one of the bones I was exporting was scaled to zero - which gave the error. Maybe your importer was facing a similar issue?

This appears to have solve the issue for now.

Cheers,
