Uniform texture normal //normal maps expect Y-up, but 2D is Y-down, so must mirror this. Go into this Material by clicking on the ">" button next to it.Ĭreate a new shader named normal_es and copy paste the following code: The Sprite's Inspector also has a CanvasItem section, scroll down to it and create a new Material. Light2D also requires a texture, and note that it can impact the color of light emitted (so white's best). Next, click on the sprite and the "Inspector" will appear in the bottom right - add your texture. It will help you understand the best way to architect your game with Godot, and prevent you from having to wrestle with the editor in the future. If you haven't done this before I highly recommend reading through all of Godot's documentation. Open up your Godot Editor and add a Node2D with Sprite and Light2D children. Spriteilluminator automated processing how to#I discovered how to do this through the Godot example. The lit textures would not dynamically interact with game lights, and thus would be more performant (ie static baking). This tool also gives the option to directly save the lit textures as a static. Once you have the sprite looking just how you want it, save the normals by clicking "Export Normals" in the top tool bar (paid version required). Spriteilluminator automated processing manual#There are a bunch of tools to manually modify sprites, I used bevel (width 16, height 100%, smoothness 8%) + emboss (height 100, smoothness 1).Ī few clicks and it's ready to go without any manual editing (though you can edit with the height, angle, structure, etc tools). Since normal mapping is more common for 3D, there aren't too many 2D tools available to create them, but a great one is SpriteIlluminator ( $40).ĭrag your texture into SpriteIlluminator's editor. They can turn dull, low-polygon models into vibrant textures, and thus help combine performance and beauty. data-oriented-design : A curated list of data oriented design resources.Normal Mapping is a lighting technique commonly found in 3D games for creating the appearance of bumps and imperfections on a texture.
