Fuzzy 2D alpha-blended images

Questions & Answers
1

I’m getting fuzzy 2D rendering in my menu system. My buttons use transparent PNGs as textures on a 2x2 plane. I’ve played with import settings, material settings, camera, etc. and all without luck. How can I get Unity to display nice crisp 2D graphics?

Notice the weird artifacts around the “Arrow” button. Those aren’t supposed to be there. In Photoshop it looks perfectly crisp.

See below the ghosting to the right of the metal frame. The gray area is simply a 50% opacity layer in order to darken the game when the Pause menu comes on.

You are using a texture compression: PVRTC 4 bits.

Change this to Uncompressed RGBA 32 bit. PVRTC is not good for images you wish to appear clear. Additionally, sometimes textures with alpha appear blurry around the edges, in such a case use Point filtering as opposed to bilinear.

Hope that helps.
