Test file: lib/props/branches.blend from Spring.
Combined weight paint + pose mode is not working well: Requires disabling Lock Object modes, which is not easy to discover. When clicking on the armature to pick a bone, the mesh does not stay in weight paint mode.
X-ray modes does not work for the weight paint overlay, would be nice to be able to see weights on backsides. Undo in weight paint mode with the brush tool active switches to the cursor tool in the topbar (but not the toolbar) Still happens when undoing mode switching.
Paint through the mesh is not working (front facing only option?) Select a bone should activate the vertex group for weight paint (not updating/redrawing?) Rotation around selected user pref not working for bones (while in weight mode?) Weight paint drawing has two issues: There are Z-fighting issues with the weight paint overlay Shading is not visible very well. Alpha can be reduced, but then it becomes hard to see the weights. As a solution to both, the overlay could be multiplied rather than alpha blended?
