Irrlicht Engine

Im trying to understand how to blend textures so I would have a nice terrain with multiple textures blended together (i.e grass and sand blended)

I have no idea how to blend them nicely so I could export it and use it in irrlicht.

I would like it too look like this



tough I dont know how to do that so I could export it nicely (I made this one myself but its using nodes and I dont know how to export it).

any help is appreciated (you can post links to tutorials but it would be nice of you if you explain it yourself here )

1. shader
2. bake the entire thing into 1 single texture

Sorry I dont really know how to bake it into single image (ps. Im going to use texture repeating ..)
and what do you mean by saying shaders?

Hmn ill try to figure out how to do this but i still would appreciate some links to good VT's
