hey there,

im quite new to houdini. So i have a scene with an dopnet and some RBD's and i'd like to slow them down with the timeshift node, but i'd like to have a extreme bullet time, about $F / 200. But if i do that this way, i also have to cook all the frames at the beginning, arround 500, which i don't need, so im asking, if i also could acitvate the time shift at a specific frame. or if it's possible to take the original frames from the sim (16 frames) and move them at the timebar, so that the 5th frame gets the first for example.

I hope you understood what i mean and sorry for my english

I think I would just sim them all out at normal speed, as a .bgeo.sc sequence. Then use a File node, followed by a TimeWarp to control the slow down.
You should be able to animate the time scale on the solver. Have you tried that?
