Hello, I am currently working on a massive crowd, I followed the "regular" workflow for the cloth with a vellum solver in post after the crowd setup but it is way too heavy.  Regarding the Hair I am working with an usd character which has proxy geo and render geo already set up. The proxy has very light geo for hair and the render has millions of curves which is very heavy and not possible to add as character shape. I don t want a hair simulation just get all the groom rendered instead of the proxy geo.   Cloth I was wondering if there were a smart way maybe to cache the simulation of the dress and bake it inside the agent. I tried to add it, but it s deforming with the bones and it s not a simulation. I also tried to add the dress as an agent shape, it attached it to a bone but it only work with a static object like a hat / weapon but not a simulated cloth.   Hair Is there a way to work with the proxy geo and then get the position of each proxy hair so I can instance all the Hair at the right position and rotation ? Is there a way to replace the proxy by the high res version in solaris ? What would be your approach, should I blast most of the curves to work lightly and then regenerate the hair ?   Thank you for your assistance, I did some researches but I couldn't find any answer in the forum.

Hi guys, @Atom I've tried claude, some nice overall instructions but the python scene was pretty broken. This is what I have so far, at least i got a better understanding on how to approach it.   houdini_XyQkhMDgGS.mp4     That said, Louis Manjares on Facebook (which also gave me some hints) tackled the reference exactly, love his result: chrome_o97jFalZu9.mp4   Cheers!  

Also it would help to share what you have so people can help and not start from the begging. 

Ask chat... I didn't get an exact solution out of ChatGPT, but I did ask it to write Houdini python code to generate a scene. Perhaps there is something in here you could lift? ap_spiral_to_magnetic_line_051526.hiplc

Update, using spring constraints and adjusting dynamically, but im struggling to magnet on the tip and create that connection like the reference any thoughts? houdini_LxHtAHVQ3h.mp4
