Hi. Been learning weight painting, used the symmetry x with mirror topology ON, but strange thing happened, I thought I was just really bad at weight painting, one part of the model rigged really badly, all broken in those area… then sometime later, I checked the vertex weight, and found R bones influence in my vertices that supposed to only be influenced by L bones, but all I did was painted in the L area of the mesh… I did this set up hoping the weight on the other side, R that is, would be linked to its respective bones… am I doing somthing wrong or the software is buggy or flawed?? hope I really don’t need to attached pics to help describing the situation. Thank you.
p.s any good image hosting site that would not contain malicious link? just in case if I do need to link pics thanks again
It could be either, or both. Rigging can be finicky, and without pictures, or access to the file, it’s hard to tell. Something to check, do you have mirror vertex groups checked? It’s in the same menu as topology mirror, and I’ve had errors similar to what I think you’re describing by forgetting to turn it on. It paints symmetrically, but the groups on the right side are still assigned to the left side vertex group. If it’s not checked, maybe try checking it. You could also check to see if your origin point is at the centerline of the model. That’s another thing I’ve had mess with my rigging more than once. If all else fails, I’ve had blender give me strange auto weights for some reason or another. Deleting all rig related vertex groups and running it again sometimes fixes that issue for me.
What do you mean by broken? If it’s just not deforming properly when the rig is moved, that sounds like bad weights and may resolve itself when you find out what’s causing your weight painting issues. If it’s physically broken, like the mesh deforms in ways you don’t want whether the rig is posed or not, that sounds more like bone constraints that aren’t working the way you want/expect, for example, a stretch to constraint that isn’t scaled properly, or a copy rotation set to world instead of local, or vice-versa.
I’m not sure on this one, somebody else can probably help you out, but I usually just screenshot the image and CTRL V it into the reply box. If I need to edit the image I open it up in my Photoshop equivalent of choice, make the edits and save it somewhere, and then drag it into the box from my computer, without going through an image hosting site. I do the same with preexisting images.
Oh, thanks for the reply. when I said broken, its like you said, deformed badly… I think you suggestion is right, and I found this youtube video: https://youtu.be/oI_TX5qblSQ, this kinda answered a lot of thing, I would just leave it here for other who stumble on these issue in the future! peace out!
