PLEASE READ THIS FIRST
I know you lose weight paints when joining armatures. This is NOT what I'm talking about. Okay, on to the issue:
PLEASE READ THE ABOVE FIRST
I am able to color the vertices just fine, but when I go into pose mode the mesh doesn't move at all.
Here's a step by step of what I did:
My separate armature pieces had 0 weights. I had tested them prior to joining them and the weights worked just great. I deleted all the weights, applied all transformations, and then joined all my armature pieces together in one Ctrl+J key press. All seemed good.
Now, when I weight paint things get weird. For one, if I click the armature and shift-click the mesh and go into weight paint mode I am not able to select bones as usual. Secondly, and most important... the weights don't do anything! I am able to color the vertices just fine, but when I go into pose mode the mesh doesn't move at all.
Is it a naming issue? Parenting? I'm new to Blender so I'm likely overlooking something very important.
