    Hey guys,

    Been using Unity on-and-off for a few years and am only now getting some exposure in to the graphical side of it. I've got an issue with antialiasing in a scene with a Tilemap and 3D models. I originally had an issue with my Tilemap having a weird rendering issue when further away from the camera:

    I googled around a bit and found the most common solution was to just disable antialiasing in the Quality Settings. However, as soon as I started importing some simple models, I had some aliasing problems (which makes a lot of sense).

    The only way I know of to fix that issue is to switch it back on, which looks nice at 4x sampling, but gives me the original issue.

    I'm wondering if there's a way to get different objects using different AA settings, instead of the global setting? I'm also open to the idea that my approach here is all wrong and maybe I shouldn't be using tilemaps for a 3D game.

    Any assistance on this would be greatly appreciated.

    This has nothing to do with anti-aliasing. Read about mip-mapping. For a quick fix, disable mip map generation on your tile map texture.

    So, looking at the Import Settings for the image I can see that the Generate Map Maps checkbox is already unchecked:
