Ocean modifier automatically makes time field purple and I cannot keyframe it

Question

I am trying to loop an ocean modifier following this tutorial, but whenever I duplicate the ocean modifier the time field automatically turns purple and I cannot keyframe it.

I have also tried making an entirely new ocean modifier instead of duplicating it, and it also starts with the time field purple.

How do I fix this?

Answer 1

Purple color means there is a driver. You should be able to delete the driver. Or better, modify it and try the world of drivers. It's amazing.
