I made a simulation with some particles and ground detection where the car hit the ground. Basically its dynamic paint and a modifier to remove the area that is under 0.01 weight.
Works fine until frame 81 where the particles just disappear or change… I assume its the children of the particles but i have not found a way to fix this.
Baking the particles is the same. Deleting and setting the particles up again is also not working… I could try to import it into a new scene…
Here the frames and particle settings…
