I have some cubes in dops that get hit by a ball. How can I record what frame each cube gets first hit at?

I.e. For each cube I want to record when another object in the sim hits it (whether it be the ball or another brick) and only the frame where it first gets hit, subsequent hits I don't want recorded.

Is this possible?

Hi,

I believe this thread [sidefx.com] has the answer you're looking for.

Cheers!

This is a file where a sphere is hitting the ground. On the first impact it turns white and stays that way. So basically you could use that information for other things.
