Ask Epic Anything: Animation & Cinematics | June 21st, 2023 at 10AM EST

  1. Can you explain how a control rig is used after it is made?

  2. Any plans to expose Morph targets and additive animation curves +keys?

  3. After using Mixamo to rig a character, I get an error when exporting that merges all bones together and it breaks the entire project animations’. What is the recommended way to auto-rig without issues like that happening (I set skeleton as a UE4 mannequin already imported into the project). Would love a little demo of that process.

  4. A sequencer does not keep state if an animation is set to play on a character, any idea why (keep state is on)?

  5. Is there any trick in simulating root motion on our own (since its not exposed) so that the character is perfectly moving without sliding their feet?

  6. Whats the best way to animate UI?

  7. Can you explain cases where additive and relative tracks are useful? I am only using additive from base, rest I cannot figure out.

  8. How can I track a state of a transform between two level sequences (I have one that sets an object in place, and another that rotates it, but I cant track the object in the second one correctly and it adds offsets, keep state is on).

  9. Why are level sequences skipping keys on wireless connections (even on high connection speeds)? Fade tracks make players stay with a black screen and custom camera may never switch back to player camera.

  10. Any plans on exposing state machines in UEFN or IK Retargeting?
