Sprite Diffuse Shader

You can use a Sprite Diffuse Shader in Unity to let your 2d sprites be affected by a light. Learn how to create it via Shader Graph, SRP/URP and more!

In Unity there are multiple ways to create a “Sprite Diffuse Shader” (meaning that sprites are affected by light sources), using both Shader Graph (URP) or HLSL.

Using Shader Graph

URP/SRP

With the addition of the URP (Universal Render Pipeline), or SRP (Scriptable Render Pipeline) you can use the “2D” rendering asset, which already includes a Sprite Diffuse Shader.

LWRP/HDRP

If you’re using older versions of Unity, with LWRP or HDRP installed, here’s how you can create a Sprite Diffuse Shader. In this tutorial I’ve used: Lightweight Render Pipeline 2.0.5-preview, Unity 2018.2.0f2.

Here’s what we’ll achieve:


PS. Oh hey almost three years ago I released a plugin called “Text Animator for Unity”, a tool I made/needed for my own games - and Today it is also getting used in other games like “Dredge, Cult of The Lamb”, “Slime Rancher 2” and many more!! I’d love if you could check it out! you’d also support me while I work on exciting stuff behind the scenes, so… thank you very much! ✨

Here’s the shader:

Explanation

In a few words: Sprite Renders need the sprites texture to be called “_MainText”.

HLSL

If you want to write a sprite diffuse shader in HLSL, you can go to the Unity Archive and install the built-in shaders for each Unity version.
