Why has my terrain suddenly gone blurry?

I had some semi high quality terrain previously in my scene. After importing a new package of some models from the store, my terrain texture is now incredibly blurry. As in, there are no details, it simply looks like a big amorphous blob of color. I tried reimporting the packages to no avail.

Has anyone encountered this issue?

A few things I’ve tried so far:

  • Starting a new scene (still have the
    issue)

  • Start a new project (issue is
    fixed then, but this is not really an
    option, more of troubleshoot)

  • Reimport the assets with the textures

  • Repaint a new texture

  • Start a new terrain

  • Make sure Project Settings → Quality is set to Fantastic

  • Make sure Terrain settings for “Pixel Error” is low (tried it at high too) and that Base Map Dist. is high (tried it lower as well)

None of these have shown any results, excepting starting a new project.

I would really appreciate any suggestions.

Thanks.

Is the shader name “Nature/Terrain/Diffuse”? If so, it replaces the existing terrain shader. Same with “Hidden/TerrainEngine/Splatmap/Lightmap-AddPass”. Those names are from the FirstPass and AddPass terrain shaders in the DefaultShaders download.

Normally, you give shaders different names, and just choose the one you want in the Material. But the built-in Terrain system has no place to pick the shader. It always looks for those names. A Unity feature is you can replace a built-in shader, by reusing the name. That’s the only way to modify a terrain shader, which is what they may have done.

It’s also possible that you have the pixel error setting up farther than it should be
