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"

Morph target not working in Construction Script

When I use a timeline in simulate or PIE the morphs work. But I can not get a morph to work in a construction script.

Hey Shoiko,

Sorry for the delay in response. We were able to reproduce this issue internally, and I have entered a new bug report for our developers to look over (UE-4489). I will let you know when I see an update on this. Thanks for your report!

Any news about this issue ? Was it fixed ?

avatar image Shoiko Apr 29 '16 at 04:21 PM

This was working in the following release. Have not tested this since though.

It seems not to work in 4.11

What did you do to show "morph" option at details panel? ( if you can remember )

Hey Lord Pol,

Set Morph Target does not function in the Construction Script (and now cannot be added to it) because Set Morph Target requires a game tick before it can function.

I'm in 4.13 and just put a "set morph target" in the construction script. Is it an error that I was even able to add that node? So there's no solution for having a model default to a morphed shape in the editor? It works fine with EventBeginPlay instead, but not when simulating.

Like I said before, Set Morph Target requires a tick to function. When it is used in the construction script, no such tick occurs (even in simulate).

No idea if anyone still has this issue but in 4.16 at least (didn't test other versions) you can accomplish this by setting the morph target in the event graph of the anim blueprint instead.

In your main BP you can create a float variable named MorphValue and expose it (click eye icon). Then in your animation blueprint go to the event graph and hook up Event Blueprint Initialize Animation to Set Morph Target. If you don't have the initialize node you can right click and add it under Add Events.

Then for the value dragging (if needed) you can do Try Get Pawn Owner - Cast to your BP - Get MorphValue and hook that up to the value in the Set Morph Target node. You can also do this in a post process anim blueprint instead if you don't want to mess with your normal anim blueprint.

Hey cyaoeu,

This is a know way of doing this and is what we were conveying in our responses. Set Morph target requires an in-game tick to function and, as such, will only work in the event graph. Thanks for following up!
