[osg-users] Check if sampler2D is valid in fragment shader

[Sebastian Messerschmidt]

Hi, yes there is:

Simply assign one Program with shaders handling texturing and the 
non-texturing variant at the appropriate state-sets. Be sure to share 
the programs (don't create a new one per instance) to keep performance up.

I can create a minimal example if you're stuck with this.

Cheers
Sebastian
