Use the Category block to group commands that set the render state, so that you can "inherit" the grouped rendering state within the block.
For example, your Shader object might have multiple SubShaders, each of which requires blending set to additive. You can use the Category block for that:
Shader "example" {Category { Blend One One SubShader { // ... } SubShader { // ... } // ...}}
The Category block does not have an impact on shader performance; it is essentially the same as copy-pasting the code.
