Landspace Material Blending

Hello! :slight_smile:
I’m working on an RTS game, and I created with BPs a system that defines seasons in the game (winter, spring, summer and fall).
So I want that each season will effect on the game environment and will change landspace’s textures for example from grass to snow.

You can see a good example of this in the game “The Settlers” (minute 0:30)

Any ideas how to make it?
