Hi everyone,
I'm trying to use a newton field on rigid bodies. I have a grid of 200+ polygon tiles rigid converted to rigid bodies. I want these to be attracted to a newton field. I've found that when only a few of the tiles are influenced by the fiel, the simulation works ok. It slows down and practically freezez at around 50 tiles. Any more than 50 and I get nothing with the time line running and no simulation at all. I have set my preferences to play all frames and also tried with large newton field magnitudes.
I also get this error "file: C:/Program Files/Alias/Maya7.0/scripts/others/timeSlider.mel line 40: Cycle on 'pCube222.worldMatrix[0]' may not evaluate as expected."
Is there a software limit to the number of rigid bodies a newton field can influence? It could very well be a hardware limit (Athlon 64 X2 4200+, 1 GB ram).

At present the only work around I can think of is using multiple fields - each with a small group of tiles.

Personally I find Maya's rigid body solver quite clunky to work with at times especially when multiple rigids are in play. One work around is to turn collisions off and have a standin object to help speed things up but not necessarily give you what you want. Alternatively there is a plugin called 'Nima' that works very well as a rigid body solver where you can have thousands of objects colliding with ease.

Another method if you have Maya 8.5 is to use nCloth which works quite well as a rigid body solver too.

Thanks Jeremy, turning off collisions worked like a charm :thumbsup:

Maya's rigid body solver is really showing its age... I'm looking forward to learning all about Nucleus!
