Rock PBR Texture Creation within Blender (Procedural) for export in game engines I've seen in Blender Docs that there are some of the procedural textures in Blender like Voroni/Clouds/Noise etc.

I've seen Substance Designer which is a good alternative to create textures for game assets/rendering. I wanted to ask if it's also possible to recreate Materials/Textures in Blender like Substance Designer?

I want to create a rock material like here - 



with heavy Bump Detailing like here -



Substance Designer just mixes textures/noises/patterns to generate materials, which I think is also possible in Blender.

There are many tutorials to create a procedural rock over the internet, even one by Andrew Price, but they are of no use here, because I want to create a rock surface (not entire rock using Blender)

From Rock Surface, I mean to create Displacement, Albedo and Normal Map which is fully procedural to create a rock which looks like the 1st image above

The first image of the Rock is what I want to recreate using Displacement, Albedo, and Normal Map

Other tutorials/blogs/ Videos are not helping me because they are not the type of rock which I want to create. Also, they show how to make a rock using Displacement Map. I want the recreation of Displacement/Normal/Albedo map, both three, not only just creation of Rock!

What do I want to create? not a rock, but a rock material, because rock material can be used to create more and more shapes and sizes of rock with different Maps


What type of rock I want to create?
this type -




not this - 



Can anyone show me a way to do this and please share the .blend file with the community?

Thanks :)

Ps - if you need any additional info or have any doubts regarding questions, just comment, I'll edit and provide additional info.

There are a lot of time lapse videos by designer which you can also use as reference while answering the question.
I worked ten minute or so and get these. I used two Voronoi for displacement, Clouds and Marble noise for surface diffuse and normal map. I doesn't look really good but you can create these blocky rockey surface like this using Volonoi as displacement map. But I really don't think it worth the effort...maybe you can do "Substance Designer" kind of things in blender, but blender is not specialized for these purpose. Unless you write custom plug-in for those kind of works, It's like digging your grave with a spoon.
