How to Make Farther Away Parts of Mesh less Detailed?

I have a very large terrain.

I would like to make it so there are less/lower poly’s when viewed from farther away, including in the inspector camera view.

How would I go about this?

Someone previously suggested that Unity’s terrain does this by default, but it does not for me. My mesh, viewed in wireframe has consistent tri density/LOD from close up to far away.

This causes a very low frame rate. Please help!

Hi, have you tried tweaking the ‘base map dist’ setting in the terrain component?

Yes but that deals with textures. I want to adjust the mesh itsself or at least how it is rendered.

maybe the “pixel error” settings. I recently tweaked this on a terrain in my game and knocked down triangles from 1m+ to a few hundred thousand without much noticeable difference
