Hi. I decided to go with single pipeline that provides big shaders and objects using own uniforms and textures to change the pipeline behaviour. I started to design a simple material format so that it resembles the one of EffectCompositor.
Thanks. 2013/10/31 michael kapelko <[email protected]> > Hi, Wang. > > I've just checked if I can use some uber shader and control its behaviour > per object by setting the object's uniforms.
