"n-gon" of LineTraces around a center point, from camera perspective

[namiredo]

I want to create an n-gon shape using only LineTraces. Fire a LineTrace “cone” around a center point (that is also a LineTrace), where each vertex of the “cone” is equidistant to the center point.

I found this example which gets me close, but it’s not quite the behavior I want - Spawning dynamic objects along the circumference of a circle - Blueprint - Unreal Engine Forums

The LineTraces orient themselves to the axis they are mapped to;

I need it to orient so it looks like a full circle from the camera’s perspective like a projection, every time.

Here’s my current Blueprint;

I understand that the steps for this are;

1. Create a for loop
2. Create some simple maths where 360/n * Index = angles of each “slice” of the n-gon
3. ???
4. Feed it into LineTraceByChannel using vectors

I don’t know what that third step is. How do I get the n-gon to orient to the camera?

Figured out a way to get it to orient to the camera, but I ran into a separate issue.

The closer you aim to the X axis, the less the radius influences the LineTraces. Anyone know why?

[namiredo]

If I aim towards the far + or - X axis (with no vertical movement), it narrows itself.

With the help of someone way more knowledgeable than I am, we got a functional oriented version.

Here’s the blueprint;
