work as I want ! but perfomance is not very good,it takes 1 or 2 seconds to parse 1 prefab file

[Ribosome2]

here is how I test :

def checkParticleSystem(prefabPath):
doc = UnityDocument.load_yaml(prefabPath)
entries = doc.filter(class_names=('ParticleSystemRenderer',))
for entry in entries:
if entry.m_RenderMode == BILL_BOARD_RENDER_MODE:
dd=1

it'a as slow as using Unity API to manipulate prefab files

The real fucking thing is the unity instance loaded by the lib cannot be pickled.

It means that There's no way to boost it with multiprocess without custom picking

I personally think it's not suite for big project.
In my project , I had to process over 10 thousands prefabs. It will cost several hours by single process.
