LOOK HOW CAN YOU IMPROVE THOSE PIXELATED TEXTURES!!! *cries tears of joy*
If you need help upscaling textures, I use this website. If you need a 1024 texture from a 256 one it IS doable, you need to upscale twice (first use the original texture, on the second time use the downloaded upscaled one). I’ve tried other websites as well, but they didn’t quite replicate the style of textures.
