In the below picture I have my terrain, the tiling is my issue, currently to get it set to the proper scale I have to use texcoords with a value of 0.00025. (4k map)
is there an easier way to have a normal map applied to the entire terrain that does NOT tile?
there should be a terrain layer coordinates node which plugs into the uv inputs of the texture. set this to the x and y scale of your landscape. this is the proper way to uv landscapes.
This is correct. Please see this documentation for more details on landscape materials:
