I’m trying to do something that looks vaguely like Minecraft, though not quite as extreme. I started with a 32x32 tile, adjusted the texture to use nearest neighbor filtering, and created a basic material from that. Trouble is, mipmapping really destroys the texture after a short distance:
Turning off mipmapping leads to flickering lines probably related to anti-aliasing. I tried all the different mipmap settings with no improvement.
Then I simply resized the original to one big 512x512 tile with an external program using the nearest-neighbor algorithm, which gave me vastly better results:
That’s not a terrible workaround, but ideally I’d like to continue using the original 32x32 textures as is. Is there any way to achieve the same results within UE4 with a tiny pixely texture? Perhaps by adding something in the material?
