### AdvancedOptions

## Multi Pass Batch

In the default URP, if render multiple pass shaders(outline), the Rendering order like this:  

Object1.Pass1-  

Objcet1.Pass2-  

Object2.Pass1-  

Object2.Pass2......  

![image-BeforeBatch](image/BeforeBatch.png)    

It will stop SPRBatch.  

![image-NotSupportBatch](image/NotSupportBatch.png)   

We can change the Rendering order like this by using RenderFeature:  

Object1.Pass1-  

Objcet2.Pass1-  

Object1.Pass2-  

Object2.Pass2......
