Question about blending materials.
polycounter lvl 15
I'm studying how to make seamless textures for a ground plane in Substance Designer.
My reference - https://imgur.com/a/j2FhLKs
So my question is about the placement of the pebbles. I want to be able to control pebble placement on each ground geo outside of Substance either by mask texture or vertex color. However, the transition, I want the pebbles to retain their shapes/outline instead of them blurring into the ground. In UE4 there seem to be a node specifically for this but I need to do this in Maya/Redshift.
Any advise appreciate. Thanks everyone.

Some tips here. Not specifically for that combo, but might give you ideas to start experimenting with.

This first video describes blending two materials using the RS Material Blender based on two material heights + a mask. At 2:00 he starts with a Ramp to do a simple blend from left to right. Instead of a ramp, this is where your own mask or vertex colors would be. Even if you're not using displacement, you'll want to have a mask that defines the shape of your pebbles. In addition to the blendColor node he uses here, there's also layeredTexture, which features a number of blending modes, like add or subtract.
Next up is the Redshift Documentation for rsVertexColor, which has a nice little primer at the bottom. Using a single R, G or B channel from this node is what you'll use in place of the ramp from the tutorial to control where your pebbles should be.
