I can’t copy/paste timeline blueprint node from one class blueprint to another class blueprint, and there is no other way to do a Paste Node function in editor, only copy.

I wonder why.

Hi asperatology,

I wasn’t able to reproduce this behavior in 4.7.3. Does same thing happen in a new project, or only your current project? Can you detail steps you took to see this behavior, including Blueprint class types you used? Thanks!

It is happening in my project. This is what I did:

  1. Add new timeline node.
  2. Double-click on node.
  3. Shift-click and add two keys. One key is (0,0), one is (1,1).
  4. Save and close timeline editor.
  5. Select node.
  6. Press CTRL+C.
  7. Switch to another class blueprint, empty one.
  8. Press CTRL+V.
  9. Nothing happens.

Both class blueprints inherit classes that is a subclass of C++ class, AActor.

Hi asperatology,

Thanks for reproduction steps! I was able to reproduce this in 4.7.3 with your help, and it looks like it was only Ctrl+C and Ctrl+V method of copy/paste that wasn’t working with Timelines. If you right-click and copy, then right-click and paste, it will work. I checked this bug in our main internal build, and issue has already been fixed. fix should appear in a future release, likely 4.8. In meantime, use right-click menu to copy/paste timeline nodes. Thanks!
