Changing the Uniform buffer before each draw seens even more expensive, if each draw would just do a single mesh - that's like having 1000s of draws instead of just 2-5. | |

Most often what makes the materials look different, is the set of parameters passed by Uniform Buffer. Are you passing a lot of additional data in your VBO? It might be possible to optimize that. | |

On your last point though I really meant VBOs - as the shader parameters are passed down per vertex at first and then per fragment - how else can you have different shader/rendering per polygon/pixel? | |
