Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Camera mounted on a Rig Rail doesn't save keyframed rotations

I'm trying to animate a camera in sequencer using the Camera Rig Rail, what I do is this:

  1. Place a Camera Rig Rail on the level.

  2. Place a Cine Camera Actor in the level, more or less placing it where I think it should be mounted onto the rail.

  3. Create a new Level Sequence.

  4. Add the Cine Camera Actor to the Level Sequence.

  5. Inside the Level Sequence, in the Camera Actor: +Track > Path > And choose the Camera Rig Rail Actor.

Now the camera is attached to the rail and it moves along it as I hit play, but the problem is that I'm unable to rotate the camera and keyframe that rotation, it always use the same rotation along the rail and ignores the rotation I just set with keyframes.

I haven't been able to find more information about the use of this Camera Rig Rail, there is no documentation about this actor.

I hope someone knows how to work with this, thank you in advance!

You need to attach camera to RailCameraMount.

Try this way:

                         1. Place camera rig.
                         2. Place camera actor.
                         3. Attach camera to camera rig.
                         4. Align camera to RailCameraMount.
                         5. In Sequenser add Camera Rig.
                         6. Camera Rig -> + -> Track -> Current Position on Rail.
                         7. Camera Rig -> + -> Track -> RailCameraMount.
                         8. RailCameraMount -> + > Track -> Transform.

Thank you so much for your detailed answer!

Now I can keyframe different rotations in the Transform of the RailCameraMount, but I have to set these manually without a gizmo, I mean I have to try rotation values until I get the camera to point to what I want, but this workflow is not ideal at all.

Is there a way to rotate this RailCameraMount with a rotation gizmo??

Thank you again!

By the way, I watched the videos you suggested but they use the rail just one time and they don't keyframe rotations at all.

Also in the example project there is no rail at all.

I'm beggining to thinkg that maybe I should animate the camera the old way, just flying around in the level and keyframing the position and rotation.
