http://forum.unity3d.com/threads/vertex-rgba-blender-2-5x.254038/ maybe this helps you.. for painting vertex alpha but I am not sure, if it works with the latest Blender version.
@Dataday: Making split vertex normal data available to export (and import?) plugins is a good thing. If that's all I'm going to get, I'll take it, and be mostly happy :) What about previewing the hard/soft edges in Blender's viewport? Will we need to physically split the edges in Blender to get an idea of what's going on,…
Ok so I'm playing around with using the node editor to modify my vertex colors, and I've realized this is probably the best way to do the vertex color modifications I want. Does any blenderhead know of a way I could use the results of the node's modifications to the vertex colors and overwrite my current vertex colors? I'm…
Any way to adjust the snapping distance of the knife tool? I often produce double vertices - because the knife tool doesn't actually snap to the vertex I click on, but places a vertex right next to it. It would also be better to adjust the functionality of the tool. Right now, a vertex is placed right where I click. If I…
Vertex weights should show up on the "n"-panel item tab, it's hidden if you don't select a vertex and it only show the last selected vertex, dosn't work for box select etc. It's quite weird or I just don't understand it correctly, but I would expect to see averaged values and being able to make changes for the whole…
You can't paint vertex alpha but you can paint a vertex group and use that as an alpha. It's a known limitation and I hope they get rid of it but it shouldn't keep you from doing anything especially if you're using any render system that makes use of nodes where you can get any vertex group weight you want.
@Pior if the mesh still has the same vertex count and vertex order, maybe it can be taken as a shape key for the original mesh. So the shape key just flattens it and the UVs remain the same.
@guitarguy00 you can't snap a vertex to the same face that it belongs to. The solution to what you want is to duplicate the vertex (the duplicate is a loose vertex), and then you can snap that vertex to any face of the mesh. You need to turn on the "Snap onto itself (editmode)" button. You can then connect that vertex…
Speaking of weight painting I wish they would properly document the weight mirroring operation ('Mirror Vertex Group'), found in the Specials pop-up menu of the Vertex Groups panel. The option names are confusing and the tooltips unhelpful. The tooltip for the 'Flip Group Names' option is "Flip vertex group names", which…
