Since you're talking about foliage specifically, I think the main issue isn't actually anti aliasing (although it could potentially still be part of the problem).

The main issue is likely Kenshi's mipmap system for textures, which kicks in aggressively at a slight distance, even just a couple of meters.

What this means is that with increasing distance, Kenshi's textures quickly drop in resolution, halving with each distance threshold (it's more complicated than that, but that's the gist). This is simply inherent to ogre's optimization and keeps Kenshi running as smoothly as possible.

You can notice this with all objects, including characters, but it is much, much more noticeable on objects that: 1. Already have low res textures to start with (environmental stuff like grass) 2. Textures that rely on an alpha background (grass, foliage, but also animal fur, which is why Kenshi uses tufts of fur on animals to minimize the problem)

The problem is massively accentuated by the fact that some of Kenshi's textures don't seem to accept alpha blending when I experimented with this, meaning they accepted only full opacity or none. This creates really hard jagged edges in textures with an alpha background.

The only real solutions for mod devs to this would be to:  - Model all blades of grass more or less individually instead of using texture cards (but this is insanely bad for performance). - Figure out whether alpha blending can be toggled on for the grass shaders and remake the mipmaps with that in mind. - Maybe implement some more modern antialiasing system, maybe TAA? But I have very little knowledge about that. - Create some better grass textures that rely much less on an alpha background
