I was recently practicing bone animation with the IK and FK systems, the problem is that when I perform the union by automatic weights there is a blind union spot that I cannot find and that deforms my character's legs, I tried deactivating the deform box of my controllers, bones and mechanisms but there is still the same error, even when I enter the weight painting and look for the origin, I can't find it anywhere.
Occurs with any movement of the leg regardless of which bone is selected.
I already have this problem for several months and I redid my skeleton several times, even then I can't solve it. many thanks.
