Subject: Deprecated setting Material or Lighting on Renderer
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=45de0062950ad822ed0379ed4fe807d333e1b8f1;p=libs%2Fgl.git

Deprecated setting Material or Lighting on Renderer

Those no longer have any special state of their own and can be set as
ProgramData instead.
