Hey!
I’m not a pro at this so I’m sure there’s a way better solution but…
what I find works for me is anything in the train blueprint you want to control needs a variable, then in the variables options there is a checkbox for “expose to cinematics”
Looking into how better devs than i use that would be a good start, but if you want a solution now you can keep reading mine (so far.) lol
Edit: check for the expose to cinematics button in your animation blueprint, that could be a better start.
depending on what you’re controlling you may have to hit the simulate game button to get the effect you’re after, so to plan the speed of wheels etc. you could possibly get around this by using the constriction script but that may not be ideal for system resources idk.
in the render it will simulate on it’s own.
This is kind of a pain cause in my case I often lose the sequencer camera while simulating, but if so you can still look at your blueprint in the level and line up the speed of the wheels and all that with the ground - then just trust they’ll move when you render. Hopefully you don’t have a camera attached to a gun or anything if this happens, cause then you’ll need a better way.
If you check expose to cinematics, (compile lol) then the variable should appear in the sequencer when you push the add track button. If it’s not right there it might be listed under the component the variable is in so add a track for that component and you’ll find it under that.
I usually click on the blueprint in the level then click the add button in the top left of sequencer, then you’ll see “actor to sequencer - [selected blueprint]”
After that it’s just a matter of finding the variable, it should be listed there under the blueprint’s “add track” icon.
Hope this helps, sorry it’s a compromise but it might help your search or get you by for now. I should also look into controlling the animation blueprint from the sequencer, that could be a lot smarter. Hey, check for an expose to cinematics tick in your animation blueprint. That might be better than my rambling answer! Haha.
(Sorry those are pics I just stumbled across this question and thought I could help. Maybe. lol)
