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"

Solid particle path line

How to get solid path line like in ufo alt text

All I managed to achieve with some beam emitters it's ragged lines alt text

I think this can be done just by using one emitter and dynamically changing of interpolation points, but I can't figure out how to do this.

Hey Givy -

I helped TheJamsh out here, https://answers.unrealengine.com/questions/136507/getting-a-beam-particle-to-follow-a-spline.html , with this issue but you can smooth out the splines by increasing the number of interpolation points.

Thank You

Hey Givy -

Those gaps are created because there is technically 3 different beam that make that spline shape. However, if you use the changes to the source and target tangents and strengths you should be able to manipulate a single beam to generate a shape shown in your example above. I would probably make the beam an actor to actor with a user defined tangent and strength.

Tangent will determine how the beam bends and in what axial direction it bends so Positive Y value means the beam will bend toward the Positive Y Axis while a Negative Y value will make the beam bend away from Positive Y axis.

Strength determines how close the bend in the beam is to the source or target (depending).

You will need to manipulate both in order to get the ultimate look you are after.

Thank You

I figured this out.

Hi, could I ask how you solved this?

I was able to set the tangents correctly, but due to each emitter having its own alignment, the intersection between 2 beams ends up breaking all the same: alt text
