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"

Sequencer not playing morph targets from animation

I have a simple animation with facial morph targets. It can play fine in the preview window of the animation, however, no morph targets are playing animation in a level sequence. I've checked that I haven't disabled morph targets for the skeletal mesh and I can see no other settings that enable or disable morph targets in the sequencer. I have tried multiple animations and none work with morph targets. Skeletal animation plays fine. It is rather essential, and seems like a huge disappointment if morph targets aren't functional within Sequencer. Any help is really appreciated.

I just discovered that morph targets are only broken when playing the sequence in the editor itself. If it is played in-game, called by a blueprint it seems to work fine. I also noticed that when in the sequence editor you stop playing the sequence, for the space of a frame on screen you see the morph target how it is supposed to be, then instantly disappears.

Thumbing through the docs on this issue seems recording game play could be a feasible work around. I haven't done anything with this yet but it seems it's a matter of recording game play for a given actor and its proximity that you set and in game play is where BP scripts and morph targets can be accessed/triggered. A sequence level is created with all the BPs, morph actions working then it's a matter of setting up new camera within sequence to capture shot needed. Again, I haven't tested this myself yet, could be wrong but I think it's worth a try.

Nothing worked. It's weird though when you record or render an image sequence the morph works or shows up in the final renders if you have it set up in blueprints first to fire upon begin game play event even though I'm not running anything in simulation. It's as if the game start Play button or event is the same as the render button on sequencer but it doesn't show up in the sequencer viewport while it's recording or on playback only in the final rendered images. Hope solution is quick on this one.

That's odd. I see the fix made it to the 4.13 release. Can you send us an example project?

Any update on this? I'm using 4.14 and the morph targets still don't play back real time in editor, only when playing the game.
