I’ve noticed that performing a SweepSingleByChannel using a capsule CollisionShape will fail to detect a hit if the center of the capsule is inside an object that would normally generate a hit.
This is a top-down view of a test cylinder and a few test capsules; the green capsules have detected no overlaps, and the red capsules have detected at least one.
This is a perspective view of the same situation, and you can clearly see that the green capsule is inside the cylinder, but it has not registered an overlap or hit.

Here’s the relevant code. It’s a little dirty.
Does anyone know what’s going on here?
My end goal is to define a brush volume in which players can spawn at a random point. Spawning players inside objects like the cylinder pushes them through the terrain and causes them to fall out of the map, which is obviously not a desired outcome. If there’s a better way to achieve this outcome that I’m missing, feel free to let me know.
