%%%arch linux kernel 3.2.11-1
nvidia quadro 2500m
blender 2.62 official release

In .blend file:
Cube.Mat.NonNode: was able to attach a driver to the material gloss amount, but while it shows up in the driver editor, the material interface doesn't recognize that there is a driver there. The Gloss Amount box hasn't turned purple, I can't remove the driver, and I can keep adding one.

Cube.Mat.Node: was able to attach a driver to the material gloss amount, but while the material interface recognizes the driver and the Gloss amount box has turned purple and I can delete the driver, it does not show up in the driver editor.%%%

%%%1) Cube.Mat.NonNode -- This is not a bug, but rather a tradeoff we had to make so that material/texture drivers could work at all given the current state of Blender's Depsgraph

  1. Cube.Mat.Node - This one took a bit of digging to find. Apparently, the driver is attached to:
    <Mat.Node.Gloss.Driver>.material
    which references Material.003

I wasn't aware of the existence of this type of linkage. I've personally found the stuff around here quite confusing.

So, I guess this makes this bug "confirmed".%%%

%%%Clarification of action plan:

  • Need to make sure that Material.Material link is considered
  • Need to figure out how best to represent this linkage. Perhaps include all of these particular linkages once at end of real material stack? There are also potential recursion/repetition issues here to resolve without killing speed...%%%

%%%Fixed in svn.

Ok, I've hacked in support for this so that these get shown now. Thanks for the bug report.%%%
