gp4vp shader profile not available - Win7, Radeon HD4890

If it’s just a matter of prefixes, then I would consider it a minor annoyance. I don’t know GLSL yet, so I’m not sure how much that changes, but from what rbd wrote here: panda3d.org/forums/viewtopi … 8114#88114 I would assume it shouldn’t be a showstopper.

Zhao, would you be so kind to share the instancing code? Or some snippets from it? I have that running in CG, but GLSL is new to me, so taking a look at how it’s done in there would help me get up to speed quicker.
