Unity Rotation In Animation Goes In Opposite Direction

Whenever I try rotating the bones of a lot of my blender-imported models, they go the opposite direction i want them to. For instance, instead of a leg going from a 0 degree angle to a 90 degree angle, it will go from 0 to 270 in the opposite rotation. Any way to fix this?

Several threads on the forum mention this and the fix to it, prior to the official fix in a recent update.

I believe it was 5.3 when officially updated. Check release notes to be sure.

From what you have said i would suggest multiplying your rotation by -1 or making it go in the opposite direction.
You probably should post your script you are using.
