How to set camera.activeTexture to bilinear filter like Pixel Perfect Camera's "Stretch Fill" does

Setting my sprite textures to bilinear makes them way too blurry, but the stretch fill option sets the camera’s activeTexture to bilinear which adds a slight barely noticeable blur (anti-aliasing). I like this and I want my cameras to always have it so that I can have smooth zooming without noticeable pixel morphing and so that my split-screen cameras can be the same size for each screen resolution, with uniform pixels (or the appearance of uniform pixels).

I’ve been trying to figure this out for awhile, tried editing the PPC script, etc. Basically what I want is a script I can attach to each of my cameras that sets their textures to be anti-aliased like that.

Thanks for your time, would appreciate any responses.

Ok I’ve found how to achieve this look! The RetroAA shader: Retro AA | VFX Shaders | Unity Asset Store

Except it’s incompatible with the palette shader I’m using, so I’m still looking for a solution. More info here: Retro AA - antialiasing for pixel art and voxel games page-2
