Troubleshooting automatic weights

I’m using rigify to rig this humanoid model I made, and I’m trying to parent them with automatic weights. I’ve grown quite frustrated over this issue, as I see in many tutorials where automatic weights works perfectly for them. Yet I get this:


What I’ve tried:

  • flipping normals
  • recalculating normals
  • readjusting topology
  • praying to the default cube
  • adjusting where the origin is

Topology:

Any ways where I can get blender to recalculate the weight paint or have it be more exact with it? I really don’t want to manually weight paint 66+ vertex groups…

Can you share the file?

It’s not the best topology for animation, but it shouldn’t cause those issues.

You mention redoing the normals. Have you tried applying scale to both the rig and the character, and then redoing the normals, and redoing auto weights after that?

Your topology is too dense and you don’t have the edge flow you need for animation, you’ll need to retoplogize

Yes here is the file:
(the file is too big, is there a way I can you the file or something?

And yes I have tried applying scale and redoing normals before applying the automatic weights

Yes, you can upload it to google drive or somesuch, and share the link. Just remember to set permission to “anyone with link” if you use google drive so you don’t have anyone bothering you for permission to download it.

Alright I need to look into that more. But would that be the cause of why the automatic weights is all messed up?

It’s almost certainly a contributing factor :thinking:

Ok ye, here ya go

I’ll look into it, I thought you only really had to retopologize if you have a super detailed model and wanted to make the animation process less laggy. But idk I need to do more research

Your faces are reversed. So I redid the basic steps, applied scale to both rig and object, then recalculated normals outside, and it worked as excepted.


That’s one of the purposes. Retopo also gives your model an edge flow that aids in deformation, like loops around the eyes and mouth.

Oh woah didnt relize that, I thought the faces were fine. Thanks for the help!
