“The trick to getting a good-looking pixel art game is to pay attention to the orthographic camera size with respect to the resolution, and make sure the artwork looks good at a certain PPU. In our game, we’re going to use a resolution of 1280 × 720 but we’ll use a trick to scale up the art a bit. We’re going to multiply the PPU by a scaling factor of 3. Our modified equation will look like this: (Vertical resolution / (PPU * Scaling factor)) * 0.5 = Camera Size Using a resolution of 1280 × 720 and a PPU of 32: (720 / (32 PPU * 3)) * 0.5 = 3.75 Camera Size This is why we set our camera size to be 3.75 earlier.”
