Help with repeat patterns
hey guys was wondering if anyone can help me solve this issue i just started getting into familiarizing myself with material editor and i started with my landscape Material
i Tried adjusting the mapping scale in the landscape coords, but anything about 13.0 leads towards stretched out low res looking material..any help would be appreciated it looks good at ground level but unrealistic with the repeat pattern
is this where a lerp would come in handy?
thanks in advance
oh incase your wondering what my material setup looks like its the basic, a mixture or a tutorial and what i see on answerhub:

Yes, as soon as you start painting with different layers the textures will break up the tiling a good bit.
The macro stuff is a way to overlay different sized grayscale texture samples in conjunction with a single diffuse color Texture Sample in order to help randomize and break up the tiling.
Here is an example of using a macro variation and lerping between two Texture Coordinate sizes of the same texture to have a non-repeating material. Keep in mind, these examples can be found in the starter content so you can reverse engineer the materials to better understand the workflow of the material editor and how certain nodes function.
Advanced Sandstone Material
I know this can be a bit intimidating at first to look at, but if you read the comments and follow the structure step by step, you will start to understand how this actually works. This example uses the same two texture samples as the Basic Set Up
Basic Sandstone Material
Essentially the bare minimum for your materials. A texture coordinate plugged into the UVs of a Diffuse and Normal Texture Sample.

I hope this helps clarify a bit on how to break up tiling and various approaches to doing so. One more thing, take a look at the Documentation as well as the Content Examples to dive deeper into Materials!
