Im trying to add my diffuse texture that i created in photoshop to my terrain i built, how to i do this ? and what format should my diffuse maps and height maps be ?
Ok so i figured out how to add the diffuse but its tiling and i need it to only tile once.
I created the terrain in world machine than exported all my maps(Diffuse,height, blah blah) and i need to apply them to my terrain, so far i have everything applied just having problems with the tiling of my diffuse texture.
That doesn’t help, i guess it has to do with the landscapecoords node but i cant find anywhere that explains how it works i dont know what to set the mapping number to if my texture is 2048, i got it so its not tilling with that node but it looks so stretched out :S here is it tiling i dont want this http://puu.sh/7M16Y.jpg
here it is with the landscapecoords node mapping set to 2017 http://puu.sh/7M1eC.jpg This is better but still not what i want.
And here is my matterial http://puu.sh/7M1hg.png
That link could actually help you if you scrolled down and followed the other links. 
You simply connect landscapecoords node to your texture map node and set mapping scale to the size , in the second image you have good result , if you mean it’s stretched it should be , you just don’t have detail texture layers for that which is covered in here how to set it up 
Landscape Material Layer Blending in Unreal Engine | Unreal Engine Documentation
After you got your layers blend them with your landscape texture map with blend_overlay node ( that’s how i do it )
and connect to base colour , that way you will be able to paint detail textures layers that blends with your landscape texture map
