I have an effect that is hiding and showing params depending on pop-up choices. Everything seems to work fine (based on Supervisor sample) but when I "unhide" the params, not only the params appear in the ECP, but they are also revealed in the timeline, which I'd rather avoid. Note that I am hiding most of the params when the effect is first applied because of the default pop-up selection. The single param which is not hidden does seem to act normally, and when it is brought back, it is not revealed in the timeline.
I tried using the PF_ParamFlag_SKIP_REVEAL_WHEN_UNHIDDEN flag, but it seems to have no effect.
Any ideas?
