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"

LookAt AimOffset interpolation not working ingame

Interpolation between animations in an AimOffset is working fine in the preview window but not at all when you are ingame. It will go instantly to the value you set.

The "AimOffset" node works with interpolation but not the "LookAt Aimoffset" node

This could be a million different things, lets see your blueprints.

I found out that the "AimOffset" node indeed works, so i changed my question a bit. But my problem from the start was that the "LookAt AimOffset" node dosen't work with interpolation.

the simplest code is to just have this in the animation graph and have a world location as input: alt text

This works, the character looks at the world position. But when i change the position the head instantly snaps to the new position, with no interpolation. If i use the "AimOffset" node instead the interpolation works.

That's because you are just setting the look at location, you need to interpolate the location and feed it into your variable as it interpolates. Here is a epic tutorial that goes over how to setup exactly this. I think Wes goes over it somewhere in the middle, but I would highly recommend checking out the whole video:

No they actually use another node called "LookAt" not "LookAt AimOffset". I understand that the "LookAt" node instantly moves the head but the "LookAt AimOffset" node is a child class of the "AimOffset" node (looking in c++). They just haven't taken the interpolation values from the parent class into consideration when moving in the aim offset graph as i think they should have.

I submitted a bug report. I'll just have to use the "AimOffset" node that has working interpolation until it's fixed i guess. Thanks for the help.
