I made a 128x128 animated spray in paint.net and VTFedit, but in game it gets scaled up. The spray is bigger than I want it to be, and somewhat blurry. Is this normal, and is there any way to get around this?
Sprays get scaled to a 64x64 unit decal in-game no matter what you give it (for reference, a player is about 72 units tall). If you want your spray to stay small, you'll have to give it a border of transparency.
