Can you have a sphere collide with the world without it being the root component?

So, I have currently made a dart-esque looking object that i have made the projectile that comes out of the FPS demo. There is a sphere inside it, and i wish to use this as the collision instead of the dart so that it can seem like it imbeds into an object. The problem is it will not collide with the world on ANY settings unless it is the root component, and if it’s the root component, the sphere is far too big for the collision, so it ends up looking stupid and can hover on sides of walls and above the floor.

is there any work around for this?

Make the dart mesh large, keeping the sphere the same size.

When you spawn it from the spawn blueprint class node, set the scale size as .5 or something.
