I was able to start painting, the it just stopped and wont let me paint at all.
I closed blender and tried again, same thing.
Please se the picture. I tried to paint each bone without luck?
Solved: Oh thats really funny! I just selected the boots mesh right after the legs mesh and started paint the top of one boot. I guess blender thought there was still an armature to attach it too.
But when I selected another bone in the boot/foot to paint, blender found the error. There was no armature mod for the boots mesh. I wonder where it put all the first painting info for the top of boot?
