You literally saved me hours of searching in 6-7 minutes. Thanks

Dude as much as I love being able to do this as a feature. It's also a huge WTF moment. Coupling Variable names with Function names is just terrible. As it violates a number of things. What if you pascal case your booleans? Now you have to do the same with a function. What if you didn't intend to call a function but happen to have the same name. Many more things come to mind but that's what's on my mind, surface level.

And now if a lot of people rely on this feature, they'll design it into a corner where they can't change the feature to have a better design.

This thing here is simply awesome!!!! Thank you for sharing, and hopefully you'll get much more deserved views!

this is purely amazing, totally saved my day🤟

Really Cool Hidden Feature! Thanks for your share. I wonder that get current frame number of sequencer in blueprint actor. Do you know..?

This is awesome! Thanks for sharing! Did a test on UE4 and it works too.

Thanks for this, I'm slowly getting familiar with more technical aspects of UE. I came across this video and your channel looking for something else. I looked through your channel and did not find that particular information. I just started looking as of this writing. I'm looking to trigger an event to un-hide assets in a room to change the environment from one state to another.

Thank you so much this is exactly what I'm looking for!!!

Hi, the best trick I was looking for month, in order to use sequencer as an artist (with feedback when pressing play).
how could you found a such nice tip !!
I don't know why but the boolean function is not working but the float one is working like a charm

[georgesmith]

Ty for this tutorial. What might be some other common use cases for this - esp. for cinematics?

[ivanc]

Thank you very much, this is a really useful tool.
I am currently trying to find a way to change the value of a key . For example, add a "transform" track for the object you want to move. And set TWO keys for the movement from the initial point to the target point (start location and end location). Is there any way to change the value of the key that corresponds to the target point from blueprint graph? (without using the method from this video / simpler way)

Cool. Are these set function calls evaluated with package/standalone build as well?

Hey buddy anyway I can access sequence components like cinecameras focal length in blueprints, edit sequence keyframes in blueprint.

Hi - nice tutorial - i search on the web how i can hide/unhide - like fading in out effect an entire 3d building with a lot of furniture inside without workig with fade material method - i can have similar material in other part of an project that will fade to invisible - i see a method with level visibility track but i want that fade in out effect - if possible not only with a building but also with parts of foliage - I want to make a camera animation and show various building construction phases. For example when a parking lot is constructed - the grass on that area to dissapear in couple of seconds All these effects to be controlled with the sequencer - but the method with fading the materials is too much work to do. Thanks.

Have you tried with the Ultra Dynamic Sky plugin to trigger thunders on specific frames ? I have been trying to do that but with little knowledge I am unable to do it.
