I want to control the background alpha parameter of a container COMP using the state of a button. To do that I am trying to connect a null CHOP to the output of a button. When the parameters of a container COMP are referencing this null (either by “export chop” or “chop reference”) the parameters are not in sync with the null CHOP. When the button state is changed it seems the container needs to cook (rmb–> force cook, navigating into the container, going to perform mode, …) before the parameters are “correct”. When using a CHOP execute to set the parameters everything works as expected. It’s also working as expected when the parameter is bound to a custom parameter from the top container that is then referencing the null CHOP.
I’m attaching a simple toe file as example.param_chop_reference.toe (4.4 KB)
