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"

Mirroring a Spline

Hello all,

I have a spline, along which I have a flat plane mesh.

I would like to create a mirror of the spline above, so that the adjacent spline mesh components seamlessly fit together vertically.

I have set up a blueprint containing a spline component, and I am creating a SplineMeshComponent using the spline's start/end tangents and locations, except with a transform providing a vertical offset.


Image 1

1 - Second spline mesh created above with an offset - they do not meet (expected).

Image 2

2 - Second spline mesh created above as before, with last two components of tangent vector inverted. Slightly better result, however meshes still don't meet.

Is there a way to get the second SplineMeshComponent to meet the first? The intended use for this is for a tillable mesh (say for a cave wall) that can be deformed using one spline, and can be offset above on a specified axis (as above).

Hello AlanEdwardes,

I believe I know a tutorial that will be able to help you out. This shows procedural generation through loops.

Hi Rudy,

Thanks for the response! That's an interesting technique, but not exactly what I would like to do here - I'd like to vertically mirror SplineMeshComponent; the tutorial goes into how to create meshes that follow a straight path to a point.
