Crowds in Skirts

Recommended Posts

Hi,

I am setting up a crowd sim and some of the agents have long skirts that will need a post cloth sim. I can't find any info on how to set this up with crowds, anyone got any tips. Thanks

added a simple hip of the crowd with skirts.

If you have not seen this video, check it out. It is a presentation by RISE and how they handled crowd shots. Basically they created paths for each and every agent then solved each agent one at a time. Cloth was handled post crowd sim on the resulting deforming mesh.

Great video ,thanks. I want to the same by setting up a post sim on the crowds to deform the cloth meshes. Not got very far yet :(

I've had another attempt but running into problems when bringing the crowd animation into a for each loop, I seem to loose the animation. I have attached a scene file.  crowdsinskirts02.hip

Here is a rework of your scene that gets one skirt simulating, but I am not even sure if you can run a dopnet inside a loop? That is why the RISE approach makes sense.

In this case I think I would simulate each agent in-place, removing locomotion. Then export each agent as a deforming polygon geometry, not polysoup. Run a cloth sim on the deforming geometry. Then return to the full locomotion crowd simulation and attach the resulting cloth simulation to the agent.

So the final scene would have nothing to do with either simulation. It would simply be a series of File nodes merged together bringing in the deforming agent mesh and the cloth simulated mesh bound with a rivet or parenting.

I don't think it will work in a loop either. Thanks for the hip. I have been able to get 10 agents to sim all in one go but it gets very slow, looking at using grains now for the cloth. cheers
