3ds max - Trouble with PF when render

Hello Everyone!)
Sorry for my English.

I have some Questions about render PF in 3ds max
I try repeat one shot from reel, just to understand how author do it.
But I faced with one trouble.

I sim in Realflow scene
export .bin in folder
in 3ds max I create PF event with realflowfilebirth and realflowfileupdate
create shape(80-sides sphere), material and cache disk operators in head of PF source bottom the render operator.
then I try to render
But in render window I see just 2\3 from all scene. In viewport I see 100% of my spheres, In render window 30-40% spheres, looks like other spheres slice and delete.
I try same thing with 20-sides spheres, all frames in render are perfect, render 100% of my spheres. Very pity what I can't use "Shape Instance" operator(try to pick geosphere with 4 segments), sometimes Max crash, sometimes wait long time when viewport is update.

Render with mental ray with default settings

And now question, what I do wrong? Why this happend?
Need your help guys!!

1) what I sim in Realflow
2-5) what In PF(Shape,RealflowFileBith and Cache)
6) what I see in viewport
7) what I see after render frame

, , , If you have any questions, ask me)
