Question about set visibility in cinematic with blueprint

Hi,

I tried to set the visibility of some objects in the cinematic by using blueprints, but they failed. I think the problem is cast failed in “cast to MovieSceneObjectPropertyTrack”. What should I do to set the visibility of the objects in the cinematic with blueprint? Thanks!

For the Track Type in “Add Track”, I used Movie Scene Visibility Track.
The value in “In Property Name” is bHidden.
Channel Type in “Get Channels by Type” is Movie Scene Scripting Boolean Channel Class.
“In Time 0” and “In Time 1” are just some random numbers.
