I've spent too much time trying to get this stupid shoulder to do what is suposed to do, and this is as close as I've got.What am I doing wrong? This shit is so stupid and time consuming and there seems to be no better tool than a fucking brush for painting. How does one achieve better results?
>>528440I use Geodesic Voxel bind method which does a lot of proper weight painting for the most part. But for painting itself, bend the arm in extremes, and then paint the influences so it looks natural. If you paint straight out you can't tell how influences will work when actually animating.I also paint in black to white in terms of values, it's easier to understand than a heatmap.
>>528448This.It might help, I'm not sure if you can see the changes when you paint in poses, but I'll try.Also, does someone knows how to reset the pose to original position? I usually pose and then Ctr+Z
>>528440I use maya, but what I learned from a rigger long ago is to set some keys on the joint(s) so that you can scrub through the timeline and see how it deforms. It's easier to see what's going on rather than painting, moving the pose and seeing a problem, going back to paint, repeat... also this solves your "reset pose to original position" question: you key the joint.shoulders are notoriously difficult though, it's ok. you can also look into other methods like helper joints, binding to geo/muscles as well.also, your shoulder joint looks a bit too far out, this is why when it bends to the side the shoulder mass seems to move outwards. it's also why when you lift it, it looks like it's bending from the wrong location (cause it is). also, note that it's impossible to rotate up your arm past a certain angle without rotating the clavicle up as well - so the shoulder shouldn't look normal that high up unless you rotate the clavicle up as well.
Yep, those shoulders are tricky.
>>528440first, identify which verts you don't want that bone to influence, then hide them with H.
>>528440Quiet right? Those models are shite, I'm surprised any of them animated properly.
>>528440The joint itself needs to be moved closer to the body. The x position should be perpendicular to the peak of the shoulder curve. Your Y position and weights actually look fine
>>528449in blender, you hit a to select all bones (or individual if you want) and use alt + g, alt + r, alt +s for resetting bone position, rotation, and scale respectively.
Weight painting is fucking brutal. The only thing I've picked up that seems to help a bit is to use tons of dummy bones in problematic places for the purpose of auto-weighting areas you want or don't want to be influenced by a parented bone.God I fucking hate weight painting so fucking much...
