How do I wake phsyics objects at a certain keyframe?

Dear community,

I’m making a VR experience and have zero programming skills. I have around a 100 props that need to start floating at a certain keyframe. There is an old video (using UE 4.6: UE4 Tutorial: Triggering Physics with the Event Track in Matinee - YouTube) that shows how to do it in Matinee with one prop, but I found it rather difficult with a 100 props.

What is the workflow with level sequence to wake physics objects at a certain keyframe? Or is there an total different way to make objects float instead of physics?

Thanks in advance!

Best way to do anything not already integrated in Level Sequencer is to use Event Tracks, listening to those events in your BPs, and do everything you want to do from there.

I suggest to read this page for further info:
https://docs.unrealengine.com/latest/INT/Engine/Sequencer/HowTo/TracksEvent/-

In your case you can add an Event in your Level Sequence and from the listener to that event (in your BP) do what you want with your physics affected actors.

Thanks! This headed me in the right direction.

Only thing is in the tutorial he is using a vector to translate a cube. How can I make an event that talks to the physics checkbox? If I select an bolean instead of the vector in my structure, I only get a checkbox but cant specify the command.

Everything else seems clear! Just that one part where I can make the event communicate something different then translation is unclear to me.
