i’ve tried to find the answer to this question with the search function, its probably me just being dumb at finding it, so ill try asking as im stuck on this problem at the moment 
What i want to do is to have different landscape textures on a single Landscape because my terrain has multiple biomes like desert, snow peaks and rocky parts. With layer blends so far i can make all of the landscape to look close to the first photograph, but i would like to have another part of the same terrain to transition into something like the 2nd photo.
So basically something like the 3rd photo (for a normal terrain not minecraft) where i can transition the terrain texture (ideally with a LandscapeLayerBlend so it mixes the textures of sand to rock, and snow to mountain correctly).
If anyone has any idea how to set this up ill be forever grateful, any help or input is greatly appreciated. Sorry if this has been asked before i swear i couldnt find anything about this topic
