Texture for cliffs question

[minimy]

There is a way to create a material within PB that detects the cliffs of the mesh to apply another texture fused with the main one.
I don't know if I explain myself well.
So it has 2 textures, one for the flat areas and another for the cliff areas and that they blend.

If you could give a simple example, I thank you.

You can solve it by different UV coordinates or multitexturing & shaders, ... it's all upon you.

Hello, it seems that I did not explain myself well.
I know how to make a .material file. Using 3 textures, 2 for color and 1 for alpha (mix between two color textures).
The issue is to do it within PB without using an external material file.
Better if mix two textures depending on the degree of slope, faces or normal. Not alpha channel to mix the two color textures.
Examples are wellcome.
Any way, thanks for help.
