How to let the particles be existence before the egg opening？

[HuaLi]

I read the docs of tyflow and watched a few videos,
docs of tyflow:http://www.tyflow.com

I know how to generate particles with tyflow,but in below example, I have two questions:
1、I don't know how to let the particles be existence before the egg opening，how to do it?
2、When the egg is open, how to let the particles drop？

1) Just make a smaller sphere, inside the main egg sphere, and spawn particles on it (volume). Make that sphere "non renderable". 
2) Add a "physics shape", and they will naturally fall. You should also add "physics collision" and add in the egg shells. 

Couple of notes: 
- You will probably need a higher physics steps settings (in tyflow icon)... so from 5, increase it to 25 to 50 
- Instead of birth and then position surface, you might want to birth voxels. That way, the parts inside eggs will be equally separated from each other, and won't collide and make crazy behavior, right from the get go. 
- start with a smaller number of particles, and increase it as you go.
