StaticMesh becomes invisible if Billboard off screen?

[Allegro]

I’m pretty new to Unreal Engine so while this issue must be super simple, I’m hitting a wall here that I can’t figure out.

I installed the Particle Effects demo file from the Learn tab and at random chose an effect and started picking it apart and rebuilding in a new file so that I could learn what’s going on. The particular blueprint I’ve started with is BP_GodRay. I believe I understand what’s going on in the material, and in the BluePrint… but the way it’s set up uses a billboard as the [ROOT] with a StaticMesh as a child. In the Example, this GodRay is always visible whenever the camera should be showing it… but in my reconstruction, the static mesh is only visible if the Billboard is on screen. Once that Billboard goes off screen the static mesh just pops out of sight.

There must be some sort of option that I’m missing here to make the static mesh visible when appropriate… any insights?

You need to make whatever root component generate big enough bounding box to cover everything that your actor contains.
Otherwise it’s going to behave like what you saw.
So if a component does not generate bounding box, use a different one as root, say a scene component.

Problem solved…

It took me way too damned long to realize that I could expand out these buttons in order to find the bounds options.
