Hello! Im trying to create niagara particles that follow spline and i want to add some offset along, for example, right vector using sample spline right vector and it returns wrong direction. Same setup with blueprints works as expected. I tried to use up vector instead, or calculate direction by using cross product upXfront but it doesn’t help. Is it bug or i doing somthing wrong?

i was trying to make it work from the past 3 hours, but it is bug inside the spline interface. Did you submitted it or not?

I’m having the same problem, but I can’t tell if it’s a bug or my mistake. Is there anyone here who knows about this?

\>calculate direction by using cross product upXfront

I tried it and it works. Thank you.
