So I have 'Add' selected on the weight paint and when I try adding weight to the knee on my characters legs it wont add anything no matter how many times I click or how I adjust the strength. It will only add weight if I click in very specific parts of the mesh not near the knee at all more towards the bottom or the top.

Im not sure if this is a problem with the mesh itself or the weight paint?

  • $\begingroup$ It's hard to tell from this screenshot only why it doesn't work. Keep in mind that you only can weight-paint the vertices. If the mesh is fairly low-poly then it's normal that you cannot paint in the middle of the face area where no vertices are. Turn on the Wireframe overlay so you can see the vertices in weight paint mode. One more thing: for animation, you want to generate the Rigify rig from the metarig and parent the mesh to it ("rig") and not to the metarig. $\endgroup$

  • $\begingroup$ @Blunder okay thank you i just added a loop cut near the knee and it fixed the issue, always did have trouble rigging low poly models but they are the only models i can do good haha $\endgroup$
