Goodmorning.
I’ve got a question. This morning I got the idea to make a nice animation of a Hydrogen Motor, how it works!
The idea came from this video:
My question is how I can simulate the Hydrogen gas, into the motor, and then get out.
Maybe I have to use particles simulations, or other stuff.
But how?
The smoke sim should work nicely,make several smoke particle generators and set them to start and stop as the exaust opens.You will need a particle generator for each time the exhaust is gonna open.
Unless there is a easier way to do it with only one.
Ok thank you!
I’ll use this.
But I’m stuck with the piston rigging!
If anyone have some experience with piston rigging, please help me!
This is the link where you can download my piston;

And I want something like the video above.
Please help me.
Just posted this in another thread:

Thank you verry much!
I gonna try it,
and when it’s done, I’ll message you! 
It worked! Thank you.
Now I have to make the Motor.
I want it looks like the one in the animation I just posted.
But How could I make it?
I dont know. 
Please tips!
If you want to see my piston, you can download it here: http://www.mediafire.com/?qrkjvgeb7xbpcbj
But If someone want to make a motor for me, please! 
Use constraints and empties,it’s not so hard to learn.
