Blender to Unity import with inverse kinematics,

Hello Guys, i have a problem when i rigged a character in blender and import it in unity… i used kinematics in blender to animate the character easily… but when i try to import this character in unity the foot (and only the foot has IK) rotates outside (in blender everythings works fine with IK) … when i try a character without IK everything works fine in unity but then i cant animate it correctly and this would be hard for the next animations like Idle, Jump , …

Here is a Picture ( left is without Ik and right is with Ik…the arms are correct like that…its the idle animation)


btw… the animations are imported correctly… accept the foots which look outside

Thank you for any help!!
