Can see terrain textures from far away, but not up close?

I downloaded a asset for snow, and when I closed out of the asset store window, my every single terrain I load up no matter what it is is purple, but only close up, if I zoom out in editor view really far away I can see it, PLEASE HELP ME, I feel like giving up on my game because of this one stupid thing

From the sounds of it, the asset you downloaded includes a (buggy) shader that declares its own “Hidden/TerrainEngine/Splatmap/Realtime-FirstPass”, which is overwriting the built-in (but hidden) default terrain shader.

From a distance your terrain will still look ok because Unity doesn’t use the splatmap terrain for that - it uses the base texture shader.

Simplest solution is to completely remove the buggy asset from your project - making particularly sure to remove any shaders it may have included, and that should resolve the problem.
