Rigging with automatic weight issue

Hello everyone, I’m currently following Complete Blender Creator 3 and am at the Rigging Chapter. I generally try to apply what I learned to personal projects, so when we learned how to create a dino, I also created a racoon. Now I’m trying to apply rigging to it, but the automatic weight is not applying how I want, and now I’m out of options.

I created this video for easy review and I can send you anything you want.

Common mistakes I checked and forgot to add in the video:

  • The scale and rotation of my model and rig are applied before parenting
  • my mirror modifier is applied before the Armature in the modifier list
  • I followed the naming convention displayed in the course and the symmetrize worked fine
  • I tried recreating the armature from scratch and starting over
  • I tried to use Normalize command and Limit range but it did not have a better result (not seen in the video)

Now I don‘t know what to do because I can apply the correct weight with paint, but I feel like I’m missing something.

Thanks in advance for those who would like to help me!

Yes, strange behavior. it’s like the influence of a single bone is huge.

How are the bones scaled?
Is there an option to influence the range …?

I’m not sure, I extruded the bones and did not use the scale command, I usually move one of the ends of the bone to shape the armature.

I don’t know if there is any option for range.

Did you try on all bones in pose mode alt r and alt s.
Which are reset rotation and scale

Yeah automatic weights heat mapping system can do some weird things. Side note you can switch to envelope bone view and get a better idea of the overlapping. Automatic weights works better with more geometry. In your case the leg bones envelope is probably just on or pretty close to the tail. Auto weight doesn’t use the envelope, but it gives an idea of algorithms overlap. You can try scaling both the mesh and the armature by 10.(S→10→enter or left click) Then do the parenting with auto weights. Then clear the scale on both.(Alt+s)
