I figured I can use 3 or 4 way vertex color to blend several textures on my mesh-based terrain ( https://docs.unrealengine.com/latest/INT/Engine/UI/LevelEditor/Modes/MeshPaintMode/VertexColor/MaterialSetup/4Way/index.html ). However, the transition between textures is just a smooth gradient. How can I break it up with some masks ? Something similar to this article: http://www.gamasutra.com/blogs/AndreyMishkinis/20130716/196339/Advanced_Terrain_Texture_Splatting.php
Would it be performance oriented way of blending textures for a mobile platform or should I use some other way of blending textures or should I not even bother with blending textures on mobile at all?
P.S. I don’t think I can use landscape material due to performance reasons, but even if I could, the tutorials don’t have any info about transition masking.
