The oddest thing just recently happened to me where I was able to use GetLocationAtDistanceAlongSpline with linear splines, up until today. Ever since, while using the same blueprint, and spline, I am now getting a return value of Vector(,0, 0, 0), when using GetLocationAtDistanceAlongSpline.
I tried searching this issue, and I could only find one instance that fits my situation, which stated that it has been reported as a bug with UE 4.9. However, I am using UE 4.14. So I am wondering if this occurrence has returned, or has Unreal been unable to find a solution for it yet?
Appearently, I tried changing the spline type back to “Curve”, and I still get the same results. So it seems that it does not matter what type of spline is used
if needed, I have included my project, which you can download it here. When opened, go to Blueprints folder and open SplineMeshComponent
Unfortunately the test project you provided wouldn’t compile on my end. So I tested this in a blank blueprint project; however, I couldn’t get your results. The GetLocationAtDistanceAlongSpline node returns a value for me when using a Linear spline. Here is the setup I used. Let me know if you are doing anything different.
