Maya Or Realflow For Rigid Body Simulations?

Postby ian360 » Wed Mar 02, 2011 1:26 am

Hey guys,

I have recently been asked to create a small project where various coins are coming out of a tap. I have used Maya rigid body dynamics in the past, but I have recently been very impressed with RealFlow when I used it in a different fluid simulation. I am thinking about giving RealFlow rigid body simulations a go for this project to see what results I get.

My questions are:
a. Has anybody tried both Maya and Realflow for rigid body simulations?
b. If so, were there any advantages or disadvantages to each piece of software in this area?
c. Which one do you prefer using for this type of work?

Any responses would be greatly appreciated. Thank you in advance.

Ian

Maya Or Realflow For Rigid Body Simulations?

Hi Ian,

Well I suppose it depends on a few things. If your talking thousands of coins, Realflow might be your answer but if it's a few second shot with a couple hundred coins then I think Maya should be able to handle it fine.

No real hassle with either package in terms of work-flow except if your constantly making changes and have to move back and forth between software.

Maya does have trouble with high volumes of objects and dynamics. Not entirely sure if RF4 rigid bodies are multi-threaded but RF5 is, which Maya is not.

I've had more luck in the last few years with ncloth rather then Maya's older dynamic system.


this might get you in the right direction of nCloth dynamcis http://area.autodesk.com/blogs/duncan/coins_with_ncloth

I have just R&D both maya 2011 nCloth and RF5 for some Hardbody sims, RF5 kicked the arse off Maya, Maya couldn't even do the sim... nCloth is good for Simple scenes tho.
RF5 is multithreaded to, try starting with Ridged/Soft Body Quality set to - Low, as this works for most scenes....

Rigid body dynamics in RealFlow 4 are not multithreaded, I'm assuming that is the version you have since this is posted in the RealFlow 4 section? In that case the performance of either is a crapshoot with many objects. Though I find RealFlow 4's rigid bodies to be less cumbersome and more user friendly than Maya's rigid bodies. Try a small simulation first to make sure pivots are correct and everything comes back in correctly if you decide the RealFlow route.

you might be able to get away with doing something like this:

but if things get heavy, maya is not going to cut it.

You can try pulldownit pluging for Maya, it is able to handle massive rigid bodies setup and it is made by the same developer of realflow 4 rigid solver.
