Hey,

If in SOPS I have a bunch of boxes that gradually turn red, how do I record in a attribute the frame they turned red at?

With some research I have found out that I should be able to do this by running my geo through POPs as POPs looks to the previous frames data.

I have been messing about but still am unable to get it to work. Can someone help me? My hip file is attached.

Thanks.

you can do it with Python. not sure if you can do it with a simple expression.

Perhaps you can run it through CHOPs via a Geometry CHOP (Animated method).

Don't worry, I worked out how to do it in POP's. Will post soon..
