Mix materials in cycles?

Is there an easier way to mix materials in cycles? I mean for example like in luxrender?

because my node setups are getting very big and complex :confused:

For example this is a simple 4-material with 4-diffuse(top) 4-normal(mid) 4-height(bottom) maps ,mixed together with 3 painted black and white textures.

I’ll give it a try, thx :slight_smile:
