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"

Matinee creating a perfect loop transition

I'm animating a sphere to move along a path, and then loop that movement. But as soon as the loop ends and goes to begin again, there's an abrupt transition because the 'path' isn't well curved. It's hard to explain, but it's just this ugly loop.

Hi artoculon!

The solution is to linearise tangents of movement keyframes so first keyframe continues the same acceleration in the same directions as the last one. To do this in Unreal you have 2 options:

  1. Use Linear keyframes (looks the best for simple movement between 2 points in space). Just Select your keyframes, then Right Click on them and choose Linear:

  1. Manually customize first and last frame tangents to match closely (when you need complex movement to be looped smoothly).

Hope that'll help!
