HI Anish, Changing state during cull isn't ideal as it limits the type of scene graph usage you can go for - running multiple cull threads will cause problems. Changing names of uniforms has to be matched to the programs that you are using and shouldn't be changed once a uniform has been created. Whether any of these are an issue for you I can't say, too much is unkown to me.
