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......

It will stop SPRBatch.

We can change the Rendering order like this by using RenderFeature:
Object1.Pass1-
Objcet2.Pass1-
Object1.Pass2-
Object2.Pass2......
