Character model going crazy after parenting For this first post, I wand to detail a weird issue for my character model. I am new to IK rigs, and I just finished my character. The armature has absolutely no problem. After having parented the model to the armature with Automatic Weights, here's what it looks like.



Hovewer, as soon as I try to move a single leg, here is what happens :



The fist leg does not follow the IK bones, and the other leg stretches abnormally, and the chest follows the deformation. I have absolutely no clue what causes this. I could create a weight map, but my character's UV map has gone crazy too. Should I fix something using the IK parameters?

NOTE : I got several issues while mirroring the bones to the other side. The control bone was absent as I forgot to add .R at the end. I finally fixed this glitch. I think the problem is rather model-related, as the armature does not have any problem.

I can send the .blend file if you wish.

Thanks for your answers.
Thanks a lot for this answer! however, how can I correct the parentage?

P.S. I cannot modify it back to high-poly, because older versions of my model are gone. I will try to weight paint now.
