Opacity parameter not working
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The opacity rendering parameter, set under "Style" in the Display panel, is not working. Opacity of 1.0 correctly shows opaque and 0.0 correctly shows nothing, but anything in between also shows completely opaque.
If you run on a machine that does not support depth peeling, you can tell that the z-buffer has been turned off, but the colors are not properly blended.
