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"

Eliminating Spline Mesh Twisting at Runtime

Hello Everybody,

I have a spline that I am working with at run time. In order to prevent twisting, that can be seen here, I am updating the Spline Up Direction for my spline meshes at run time. This eliminates twisting completely, but it causes a new problem where the spline meshes become out of sync as you can see in the pictures below.

Side Note: In the pictures above the green lines represent the Spline Up Direction and the static mesh used for the spline meshes was a simple cube. As you can see in the pictures, the spline meshes do not have a smooth transition.

Side Note: The actions in the Blueprint above are being run in the Tick method of my Blueprint.

Main Question: Does anyone know how to update the Spline Up direction of a spline mesh at run time without causing the desync issue that I have stated above?

Thank you for your time,
