I'm having a problem where I want to have my dops sim start at frame 80, I set the startFrame on the autodop network to 80 and the “Creation frame” on my rbdFractured object is set to frame 1

when I run this sim I sometimes get the rbdObject to initialize correctly, and after a couple times running it, it ends up not initialzing anymore.

if I set everything back to frame 1 then it works properly, but I have to wait thru 80 frames of SLOOW runup of nothing.

is anybody else having this issue? or does my workflow not compute to anyone?

thanks

you need to check Creation Frame Specifies Simulation Frame checkbox on your rbd if you want it to be created on the first frame of the simlation which is 80 in your case
otherwise it will be created on frame 1 which is not included in the simulation so it will not be created
(if you have your simulation cached then it will be there, but as soon as you resimulate it will be correctly updated, that's why it may seem that it sometimes work)
