This is just a single texture with all of your sprites contained in it, in a grid:Įach sprite prefab has the same material assigned (more on the material assignment in a minute). You can solve this problem by creating a sprite atlas. Every unique texture in the scene triggers a GPU context switch at runtime the more unique textures you have, the more context switches have to happen every frame, and thus the worse your frame rate. The simplest way to do this is to assign a different material to each sprite prefab, which contains an image of the sprite you want, but this actually has a nasty hidden performance cost. To create different sprites you’ll need different textures. like you would in 3D, just making sure that they all use this quad model. You can make prefabs for different game objects - enemies, pickups, effects, etc. In Unity, you’ll import your quad and then set up a prefab consisting of a MeshFilter and MeshRenderer, so that the mesh can be seen. I don’t recommend this, because the Plane primitive actually consists of a 10x10 quad grid, meaning each sprite will render 100 times the amount of geometry that you actually need! Incidentally, you may be wondering if you can just use Unity’s built-in Plane primitive instead of modeling your own quad. Why is it important for the quad to face down negative Z? Because you want to set up your game camera facing down positive Z in Unity so that world XY correspond to screen XY, and that means the quad will need to face the opposite direction so that it’s facing the camera, and thus can be seen. I also applied a planar UV projection to normalize UVs across the face. It’s just a simple one-sided quad, 1 unit to a side, with its face normal pointing down negative Z. I made mine in Modo, my modeling package of choice. ![]() You’ll need to create and import a quad to use as your mesh. ![]() Each sprite in the scene is a single, textured quad, positioned in 3D space just like a regular model. The first thing to understand is that even though you’re making something that looks 2D, it’s still technically a 3D scene. ![]() #Unity 5 palette swap single object how toThis article is not a beginners’ tutorial: I’m assuming you already know how to use Unity in a 3D context and are just looking for some pointers on how to make it work for 2D pixel art. I’m going to present a brief overview of a number of techniques I’ve used to create a classic 2D “pixel art” look in Unity. I’ve been creating 2D sprite-based games in Unity for two years now - games like Conquistador and Fail-Deadly - and in this article I’m going to show you the techniques I used to achieve the classic 2D look. Unity is well-known for being an easy-to-use, cross-platform 3D engine and toolset, but that doesn’t mean you’re forced to make an FPS or third-person action-adventure game. ![]()
