I tried to find a solution to this problem for almost a week, but not a single KZbin video helped me. Today I came across your video - and it worked, I'm really very happy. If I had found this 3 days earlier, I would have saved several dozen hours of my life. Thank you.

[@amv.neptun]

Was starting to lose hope watching 20+ tutorials on this topic then the solution I needed was just scaling my objects? Damn. Thank you sir!

Scaling method worked like a charm on a quite complex character mesh. Thank you so much!

Yep fixed it for me to, was confused when the merge didnt work but this worked immediately

[@Shattered3582]

you are the ONLY video that actually covers this in detail. I couldn't find anything that actually explained how to deal with this weight painting problem. it feels like a dirty secret that everyone else knows except for yourself, and no one shares their tips. thanks CGDive

Nice! Yeah, everyone bumps into Bone Heat sooner or later. I just took the time to gather and figure out the most common solutions :)

I hope the Bone Heat Weighting error rests in peace, indeed I do. Thank you ever so much for this video. My prized approach was cleaning up the mesh then separating by loose parts.

Awesome! :)

[@Randomplushchannel01]

Idk if this is said in the vid, but you can just manually remove vertices that are too close or just messed up, just dissolve messed up vertices and you’re good.

[@llscypherll]

Love u so much i spend 2 hours trying stuff for my rig to work but 3 minutes of your vid worked

[@CGDive]

Nice!

[@cynth4941]

Haven't looked at the whole video, but one thing that I'll say is to look at your shape keys and preferably disable them all before rigging. Yesterday I was having this issue, and it was driving me crazy. I did some sort of impromptu "binary search" by selecting half of the mesh, splitting it and trying to Automatic Weight the split part, seeing which part fails, split it in half again, see which part fails, split it again, .... Until I was able to pin it down to 3 faces. But those faces weren't intersecting at all, they looked completely normal to me. Only when I turned all the shapekeys off I noticed that the faces had 0 size on the Basis shapekey.

[@ravilucky9327]

Thank you sir I am from India your vedios help me a lot and save my time from 3 days I am searching a solution for this now I fixed the issue by watching your video

Happy to help!

[@crystaltigeranimations4949]

Oh man, thank you. this is kind of embarrassing but the first solution was the solution for me, i had merged it a few times before but after editing a lot i guess i just needed to do it one last time! It knocked out 4200 vertexes if you can believe it. This model is just for an animation i'm doing, so it's fairly complicated. Thank you so much!

[@CGDive]

Glad it helped

[@ExistentialPineapple]

thank you so much for this tutorial. I've been dealing with frustration around this topic for probably close to a year now, and finally having an answer to this has given me so much joy. I think it's silly that there have to be *this* many workarounds for a rig, but I also wonder if the scale one (that was the solution to my issue) has to do with the world scale settings in place? Either way, thank you so much for this tutorial. I cannot say how appreciative I am of your work and time spent doing this :)

[@CGDive]

That's great to hear. And yes, world scale will probably affect how automatic weights is applied but I am not sure if there is a solution that involves tweaking it. If you find one, let me know.

[@mixchief]

@CGDive Just wanted to say that your channel has quickly become one of my top choices and I subscribe to probably 30+ Blender channels ;-)

[@CGDive]

Thank you very much!

[@HS-od4ei]

Ah, method 1 solved it. As expected, it appears that the cause was an overly complex and sophisticated model. I guess I'll have to use a different model. It was a great help. Thank you!

[@9s322]

Solution 3 saved my life! You earned a new sub!

[@CGDive]

The amount of "saved my life" comments under this video is staggering. I am happy :)

[@Patxi__]

Thank you!!! In my case was the 3rd solution. It is a character made in 3d coat and autodecimated and it was keeping the different meshes merged from 3d coat.

Thanks lord, I knew I was doing something wrong and the vertices thing helped me resolve the problem, thanks a lot.

[@CGDive]

I have a bunch of info on Weight Painting. It's getting a bit old but the general information is still valid. It's mostly some interface and keymap changes that can trip you up. kzbin.info/aero/PLdcL5aF8ZcJsFEdlMJ7To0Iu9s-XCFV3W

[@OviGomy]

You saved my life! The Scaling method works!

[@noprofile6845]

First off, YOU are a wonderful person... Scaling to a hundred thing fixed my (6 legged 6 armed) alien (I've actually been banging my head on bone heat death for years, usually cutting up the character, auto weighting the parts that will, hand painting what won't, joining it back together and fixing the weights at the boundary)... Now I wanna know WHY does blender have this stupid scaling issue, I wanna call it stupid, but bet there is a good reason I just don't know... Looks like this's a fix for getting cloth sims to work changing the cliping distance If your makeing very large scale scenes

[@CGDive]

Yeah, I don't know why there isn't a setting that has the same effect as scaling the objects but without actually scaling them....

[@CraigMoro]

Thank you so much! Just saved my final project for a blender class

[@SanyaBelyi]

Thank you very much for showing that there is such an addon for Blender 3D, I'm just a Ukrainian and I didn't find a solution to my problem in the Russian-Ukrainian speaking segment, as you described the first method, then most of them talked about this method, and with this addon even a beginner like me can do not very high-quality models with bones and do not suffer with merging by distance, of course it works, you need to enter large values to work, but it greatly spoils the model, beginners are not able to make models so well, thank you again, I will tell you about this addon

[@susufrernlp93]

You can save yourself from weight painting manually with the option in Weight Paint Mode > Weights > Assign Automatic From Bones. It's basically the same effect as Automatic Weights, but for one bone only. Just a tip in case only the last solution works.

[@CGDive]

This is a good technique but I don't think there us any automated method that makes manual weight painting completely unnecessary. I recommend learning it.

[@susufrernlp93]

@@CGDive Oh yes for sure. There's always corrections to do. Using Assign Auto From Bones helps do the heavy work faster, that what i was trying to say.

[@MrGravicaper]

Something Blender is completely broken in the context of the skin. I can't seem to get the auto normalize option to work. And specularity almost doesn't work when you paint a weight on a bone on one side and assign similar weights to a symmetrical bone on the other side. Maybe Blender version 3.6 is not stable? Today, until 5 am, I tried to start auto normalization using this video and other sources on the Internet. I really want to work only in Blender, but it seems that I will have to complete this task on which I am currently skidding in Maya.

[@ChilligerHund]

I've tried every method and nothing works... I even bought the add-on but my blender freezes whenever I try to voxel heat diffuse. I dont know what to do :( My mesh has some shape keys, does that effect anything ? But even when i deleted my shape keys it didnt work. My normals are fine, my mesh has good topology and no loose verticies. However when I go to select->select non manifold, i get one loop around the eye which is a non manifold. Do you have any idea what else I can do ?

[@bongo6_462]
