Please add Terrain-Blending support (Microsplat)

I'll clarify: if your biomes have MicroSplat node, there is no way to make it work unless higher level node has MicroSplat too. But then it textures twice: 1: from higher level 2: from biomes

I will appreciate if you could clarify what is textures twice. Any screenshot, or maybe description? Thanks!

Dunno if this ever got resolved. but the regular textures get "automagically" alpha-blended when used in biomes as you know. However the Microsplat output has a different idea on things and oddly there is some kind of dependence.

I did try some testing. Adding a top layer that had all 16 MS channels and doing an exact copy of that (texture order, everything) in the other biomes. And even then it seemed like the requests from further down the chain on some other layer would just over-write the requests in another layer. Not neatly blend them which is the experience with the built-in.

It's the reason we built the horror story 64 -> 16 mixer we currently use. Manually mixing the values works just fine. to one FINAL Microsplat output. but having multiple ones makes "bad things happen"

Hope that clears it up.
