![]() The most important thing to remember for our purposes is that one material will generate multiple shaders. This is why you’ll sometimes see Unreal developers using terms like ‘material’ and ‘shader’ to mean the same thing. It both defines the shader instructions, and sets the parameters it will use. In the editor, each node represents a module of HLSL shader code that can be linked together to create a custom material/shader combination. ![]() In Unreal it gets a little muddy because when you’re using the node-based Material Editor you’re making both at once. It defines the parameters that the shader then uses to generate an output. Assigning a texture, setting a color value for example. You can think of a material as the input a developer feeds into a shader to get their desired result. This can sometimes be a cause for confusion as although they are definitely not the same thing, in Unreal the line is somewhat blurred. This is especially prevalent in Unreal-engine centered forums and message boards. In your adventures online you may come across the term ‘shader’ being used interchangeably with the term ‘material’.
