I recently released fy_pool_day for CS2.
For it, I made a few custom props of inflatable toys that the players can move around and deflate :
I've been asked a lot how I did this, so I made an in depth tutorial for it.
It's not just about the Ragdoll part, it covers everything from the cloth simulation used to create the high poly mesh to the end result.
It's a long video so don't hesitate to use the chapters if you're already familiar with the concepts shown in the video.
