Shaders are referenced inside of a material-script. PB loads
one material-script for every entity (when using #PB_Material_None).
At this point, PB supports the whole functionality of a material-script,
that includes shaders. As i remember, there is the possibility to
set (and get?) shader-variables. But i haven't done anything
with that ... so i can't give you a working example or a hint,
how a shader needs to be implemented in a material-script
There shouldn't be much differences from PB-OGRE and
OGRE itself. So if there is an example in the OGRE-SDK,
that does this ... you can use the resource from that as a
beginning.
But if you get a toon-shader working with OGRE and PB, i
would be glade to have an example, too.
