Create a landscape mesh with gaea or something.   <\/span><\/p>\n

\"\"<\/p>\n

Add a new blank material<\/strong> and go into the shader editor<\/strong>.  Change the color to dark green or something so you don’t go blind.
\"\"<\/p>\n

Slope mask<\/h2>\n

Geometry node
Seperate XYZ (vector)
color ramp<\/p>\n

Make this setup to make the slope mask.  You will probably have to move the black slider to the right to see the effect start to work.<\/p>\n

\"\"<\/p>\n

To see the mask preview, hook it into the Base Color input on the Principle BSDF node.<\/p>\n

\"\"<\/p>\n

Using the mask<\/h2>\n

We can use a “mix” node with this mask to lerp two textures.
To add a new texture to combine, copy the bsdf node, select it, then press ctrl + shift + T  (enable node wrangler add on for this hotkey)  and select a texture set to make a texture.  
\"\"<\/p>\n

This will create a new shader inside our material.  You can mix different shaders in one material if you have a mask like this.<\/p>\n

Do this again for a stone shader.<\/p>\n

Then add a Mix Shader <\/strong>node. <\/p>\n

Connect your bsdf nodes into the inputs and your slope mask into the factor, and your materials should now “lerp” according to the slope mask.
\"\"<\/p>\n

\"\"<\/p>\n

Adjust gradient value in the  slope mask for more or less falloff.<\/p>\n

If you connect the “generated”
 slot instead of the “UV” slot from the  texture coordinate node on the rock texture you can get a more “world based” \/ triplanar tiling.  This is useful if your rocks are mostly “protruding” \/ vertical.  You will probably have to mess with the scaling but if done right you can get something like this.<\/p>\n

\"\"<\/p>\n
