Terrain Blending

The previous shader we had for blending only supported 2-way blends and wasn't powerful at all, it caused a lot of trouble for ourselves and the community to idealize the vision wanted for our worlds. This month I wrote a new one that is also being using as a base for the future user-created shader workflow.

Blendable should support up to 5-way blends ( Limited to 4 due to GPU register pressure at the moment ), so you should have no shortage of possibilities to create.

This should have the same workflow as standard PBR shaders and its shading is consistent with them too, so people should be able to just use it with a familiar workflow.

Additionally, more than just being able to blend through textures, you can use blendable to tint your geometry in any way you want for free.
