Hello guys,
Here is a doubt I am having.
parameter value has changed in the dop so.. dop has done with saving sim checkpoints.
the parameter changed is based on the @Frame.and the parameter is taking effect after one of the saved sim checkpoint has.
so doing the sim after the check point is useful or it has to be done completely from the start of the dop start frame to take effect of the changed parameter.
Thank you in advance for helping

it has worked, just doing the sim. one thing to keep in mind is to delete or empty later checkpoints and keep only the check point where it has to be started from. if not the sim will be messed up with later check points data. and start the sim on or any of the after check point frame
