I have a virtual production need for sequencer. I have level in which four vehicles need to be conveyed along a roller coaster like track, and I can’t figure out a way to do this procedurally in sequencer.
The track is a spline mesh blueprint. I want the vehicle on the track to “listen” to the spline defining the spline mesh track or the spline mesh track itself so that I can convey it along the track with keyframes much like a camera on a camera rail track.
It is mission critical that this is accomplished in sequencer as this is a VP job that needs individual shots set up.
Have you tried the Path Track in Sequencer? If you add your object to Sequencer, you should be able to add a Path Track and assign the spline as the guide for that path. You can then control the distance along the path with keyframes.
Path track! That is a new set of words for me! Where is that to be found? does it matter that the spline I need to refer to is in the spline mesh bp actor?
Oh great! I had a feeling it was something very simple that I was missing.
My issue is almost resolved. How can I offset the object once it is set on this path? I need the object to float above the mesh at a set distance. When I add transforms to the object after the path is set the path seems to override the transform variable. I tried making the object a BP actor, but the only transform variables I’m seeing in the BP viewport are scale variables.
Thanks again for your help. Once I can figure out how to offset the object’s location I’m good to go!
You should use an intermediate node/actor/static mesh. Attach that intermediate actor to the path and then attach your actual object to the intermediate actor. Then, you’ll be able to move your actor object relative to the intermediate actor (which is on the path).
Thanks again for the advice I just got around to trying attaching my spaceship mesh to an intermediate mesh that was pathed to the track and it didnt behave how I expected.
The first image is the starting point of the ship. You can see the purple track that it is supposed to follow beneath it.
The second image is what happens when I attach the ship to the intermediate object pathed to the track spline. It teleports to some far off point. You can see it’s transform control axis off in the distance. the spacehip does path, but it seems to be oriented in some wonky way. Also, as the ship paths, it does rotate to always be facing forward, which is what it did when I just attached the ship directly to the track spline.
Most likely you should reset the relative transform (ie. set trans/rot to 0) when you attach an object to another. This will snap it to the other object because otherwise if you keep the relative transform of the object, it will move away since it is inheriting a parent transform.
