I know this issue has to do with weight painting but she's already weight painted so I don't really understand how to use that to solve this? It happens with the whole body in general when she moves.

I've also dabbled with using collision objects but those don't seem to be much help - and I don't want to have to add them each time I need to make another animation.

A once off whole body solution would be great.

  • $\begingroup$ Hi - My question was edited (not by me, idk) - but in my original question I explain that I'm just starting out with blender. Some of the suggested solutions were weight painting the affected areas, and using collisions but these are not really solving the problem. Here's the file. $\endgroup$ Jul 18, 2023 at 20:43

a mesh intersecting with itself shouldn't be a weight painting issues, rather than an issue with the animation itself. I assume the character has a rig, I would recommend editing the animation and moving her hand outside of her head. I'm not sure outside of that what it is that you could be asking.

-----Update---- So I looked at your file, and you've got your work cut out for you. I would recommend setting up an IK rig before doing animations because it will make your workflow much easier. But you need to set your bones to show up as "In front" to allow you to make easier bone selections (recommendation). Being that you have so many keyframes you will have to do a lot of adjusting to make it look the way you want it. I just redid a little bit of the animation adjusting only her Right arm using three bones to prevent your problem from happening. Making small adjustments throughout multiple keyframes to make sure her hand didn't phase through her skull. You can do this for any body part that phases through her body. You can save your adjustments by hitting "i" and choosing location, rotation, and scale, or you can make sure auto key is on in the timeline bar.

  • $\begingroup$ Yes, it does have a rig. I want to know to prevent limbs moving into each other with the various motions, so it looks more natural. $\endgroup$ Jul 18, 2023 at 20:49
  • $\begingroup$ Did you make he animations with that character or did you import them onto the rig serperately $\endgroup$ Jul 19, 2023 at 0:37
  • $\begingroup$ What you need to do is adjust the frames where the hand is going through the body with the armature and replacing those keyframes. You just need to edit the animation. if you send me the file I can make a short video for you on how to fix it $\endgroup$ Jul 19, 2023 at 0:38
  • $\begingroup$ nvm I see the file, you should add that in your question next time so we dont miss it $\endgroup$ Jul 19, 2023 at 0:40
  • $\begingroup$ Thats a lot of keyframes, this will take a minute to fix $\endgroup$ Jul 19, 2023 at 0:42
