How to have the character only see grass nearby?

I imported a project made by someone and I noticed that I can only see foliage grass nearby wherever I went. My pc does not have to render grass far away from me, and this saves lots of stress of my gpu. So my question is how would you do to reach this effect.

As you can see, the grass shows up only in the region surrounding the player. In fact, the whole landscape is covered by grass.

That worked. Thanks.

It’s just the cull distance in the foliage:
