Hi,

I am trying to do a simple RBD simulation and I am getting strange results. I am trying to make a car smash through some tables and chairs, which does work to some extent. When the cars hit the tables and chairs, the geometry just goes flying off into oblivion and in the complete wrong direction. I have tried just simulating one table to work out the problem but I am getting the same results .

I imported the animation and geo from maya with no history in the file so I dont think it could be that.

Because the file is too large with the car geometry in, I have animated a cube to replace the geo.

Any help would be great Thanks

Hey,

I have created a smoke sim from a particle system for a train locomotive and so far I am pretty pleased with the result except for one problem.

The problem is that I want the density of the smoke to die off gradually after the particle has been alive for around 100 frames. I wasnt sure if I was to add an age expression or node to the POP network to fade out the opacity of the particles. I also have a volume visualisation, I was thinking of adding an if expression to the density scale to fade out the density over time?

Thanks for looking.

Thanks very much, that works.
