I have to animate a customers product conveying on conveyor belts.
I will need to have something automatically generate the boxes at a certain point being the infeed section of the conveyor and they have to react to physics. The customer wants to see the maximum rate of the product and weather or not the product will be able to climb the inclines that we have in the timeframe alotted.

I’m using a pathdeform wsm to animate the conveyor belt.
I know I can simulate physics with reactor. I’m not sure how to autiomatically generate the boxes. Do I use particle flow or something else.
I’m using 3ds Max 2009. I’m also using Mental Ray.

Any insight anyone can give me would be greatly appreciated.

Thanks,

IMO Max and Reactor are not really suitable for test simulations of real world product in this way. I think of Max as more of an artist’s tool rather than an engineer’s tool. It does things to appear to look right, but not necessarily physically accurate.
This is true for how Reactor works, it’s a physics sim, but not a physically accurate one, it uses a certain amount of random chaos to give the impression of natural movement, and rigid bodies are rigid, there is no give in them.
Weather or not boxes stay on a conveyor on an incline is dependant on a great many factors that reactor is not capable of simulating.
The mass of the boxes, the angle of incline and the friction of the box and conveyor materials have settings, and you could maybe make it work in Max, but that’s no guarantee it will work for real. The dimensions , incline and mass (in Kg) can all be set to scale in real world units, but the friction parameter, a critical one, not sure how that relates to any real world unit.

Thanks for the quick response.
What you say makes sense.
Is there still a way to automatically create a series of boxes at certain intervals to randomly go up the conveyor and react with the physics.

Particles don’t work with reator. Maybe with a script you could make random boxes. I’m not in to scripting.

Thanks for the info.
Does anyone know how to achieve this with scripting?

You could try asking in the Script section
