Terrain Blending Tool (based on Star Wars: Battlefront)

It would be nice if you could somehow turn this into a material function that you can just add to an existing material in order to inherit the functionality. Otherwise you’d have to re-work all of the materials for your static meshes to include this blending functionality.
Looks fantastic though. Especially like the idea of the Automatic blend material… that would save a lot of time over having to hand paint out the seams manually.
