# Why is my model distorting when I weight paint?

After importing a .OBG file and rigging it, when I weight paint, my model deforms. I use Blender v2.77 .

• Did you use IK (as mentioned in the tags) ? – lemon Jun 27 '16 at 5:10
• yes. I mentioned Inverse kinematics in the tags. since I used inverse kinematic on the legs, the only area that is affected by the deformation. If I paint over the legs, everything deforms. – F. Lu Jun 27 '16 at 22:19
• This is probably due to that : have a try. Disable the IK and test if the behaviour is the same when painting – lemon Jun 28 '16 at 6:01
