Mesh is partially broken when exporting animated character to Unity

I spend like 12h trying to export my animated character to unity and his knees are always broken. In 3ds max the model is perfect and nothing is broken. Exporting in obj seem to work but I dont have the animation. I'm using 3ds max biped. I have look only and I found nothing. I try to export my character to blender then reimport to 3ds max. I used a script to copy my skin and my model and it work in 3ds max but when exporting to unity, the knees remains broken.

This is my last solution either my mesh is corrupted or I have to remake a character.

 

Thank you for your reply!

Texture is working fine in 3ds max, the model is acting normal when I play the animation. I look in 3ds max to see if there was not another object clipping and I found nothing. It look like the skin modifier break when I export my character from max to unity. I try many different way to export and the hips/knee area is still broken.

 

I discover that what is affecting my character is: the "Bone affected limit" in 3ds max is set to 4 but in unity it behave like it was set to 1


How could I change that in the engine?

 

Find a SkinnedMeshRenderer component that corresponds to your character mesh, then set its "Quality" parameter to 4 bones (default "Auto" never works correctly)

 

Thank you buddy for your help! This is the first time it happens to me, I think it has to do with the recent change in unity.

 

No problem, for me this BS was strangely common occurence
