Re: Blowing away an image with wind?

Hi! 
After a few days of attended to you answer  has arrived...

Premised that I use 3DSMax 9, trie this way:

Create an object Cube
Create a PFlow
Insert spacewarp Wind and Drag
Insert a deflector above the cube.

In Autokey, moves downward the deflector from the tall one for the whole length
of the cube. 
You must see the deflector that passes through the cube...

Open Particle View and in the Event01 replace Position Icon with Position
Object. Click above the cube after you have selected Emitter Object. 
Hide the cube in the window of visualization.
Always in the event01, you insert Collision Spawn and click on the deflector.

Create a second event with Force, Speed by Surface, Delete.
Open Force and click above Wind and Drag, open Speed Surface and click on the
Cube
Link Event01 with Event 02 and voilà... press play and you see what happens in
the animation...

Note as the particles of the Event01 are firm on the sufrafce of the cube, and
when the deflector crosses the Cube, them him traform in new particles that are
born from the Event02.

Now you must setting all the parameters to create your simulation!! 
This reference is only a line drive for creating your effect..

PS:
I would thank publicly Allan MacKay to have made to understand me and to know
the world of the flow particle!!!

Good job 

Ciao
