To Reproduce
Steps to reproduce the behavior:
Sorry, I'm a Chinese user. Maybe Baidu translation will have problems.
I want to use the custom vertex streams node of the original particle to control the dissolution or flow of the map. The shader connected with ASE can take effect without adding UI particle script. However, after adding UI particle script, the renderer of the original particle will not be checked, and the custom vertex streams node inside will not take effect.

Expected behavior
I want to control the UV flow and dissolution in the shader through the custom vertex streams node, and the UI particle script still works
