whats the best way to mix tile textures?

Yonderboy

Hi,

Im creating a low-midpoly town that id like to be as modular and customization as possible, and im wondering what the best way to blend between different tiles would be? For example, i have some road tiles (attached) and im going to make a tile that is just grass, but I was wondering what I should do if i wanted to have a nice transition from glass to pavement or pavement to mud.  The only way I can currently think of is either create another bespoke texture - or perhaps have a layered material that has 2 textures which blend using a matte?.  (Currently each road tile has 2 textures... 1 tiling texture for the pavements and 1 texture for all of the tiles road sections)

Ive attached an examlple of what i mean

Are there any tricks that I dont know of perhaps?

thanks a lot for any help!

Normally you would have a multi-layered material as you said, and use something like vertex color to blend between the layers. UE4 has a tool built in for doing this with terrain.

Hi Zack!   Yes, the unreal tool looks really cool. Unfortunately im using Unity :-/   Perhaps I could find some kind of shader that will do this. 

thanks for your help

I shared some techniques I used in Unity for tile blending here.

I looked into painting vertex color directly inside Unity, but the performance overhead wasn't great. Might as well pre-paint the blends in your 3d modeling tool, which I did in 3ds Max.

thanks - ill take a look!
