Do you have advice for "bone heat" error after automatic weights?

I tried merge by distance. Apply all transformations on body and armature.
Do you have more advise?

I also watch YouTube videos and try that.
How do you take care of the error?

The body of my character deforms or net everything goes along with it while it is parented to the body.

Check out https://blender.stackexchange.com/questions/15964/heat-weighting-failed-to-find-solution-for-one-or-more-bones/230382#230382 .

Thank you! It helped me out

The scale of the model and the armature relative to the scene unit tends to be the biggest issue. Just scale the armature and the model apply skinning and scale them back to their original size. Not the slickest solution but it works.

I actually found that out through YouTube. Nothing else helped or I’m too much of a beginner to take a better look at it.
That was the only thing that helped :smiley:
