Hi! It's easy to do with blend4web too. I prepeared an example for you, where I baked an AO map? as in the tutorial and them mixed two textures using baked AO as mask.
grenade.blend

Thank you very much Mikhail!
I think uv mapping the trouble
- my UV Mapping
I do not can because of this vertex paint -> paint -> dirty vertex colors - to prepare dirt in painting.
But I learned a lot based on the example

Yes, for this method you need to use HIPoly mesh, but better just to bake AO to the texture.
