How to add color to USphereComponents for visibility


I am looking to add a visibility component to USphereComponents in game without the wireframe associated with it. Right now, I am working on a spherical area blueprint that, when entered, applies a specific effect to the player character. I am wondering if I am able to add a visible color to the outside of the sphere, or any other particular type of approach would be welcome. I wish to avoid putting a post-processing volume in the sphere, due to its repeated use and possibility with clashing with the main post-process volume in the scene.

I’ve made some progress, seeing that the sphere component has a shape tab that allows shape material, but I am unable to apply any translucent materials; it just appears as blank and not present. Why is this, and how might I be able to fix this?
