Reflection doesn't work

I’m a novice in game making and i’m facing this problem:
if I try to place a reflection sphere capture it works for existing objects and materials like the chairs, the table and the floor in a new blank project, but it doesn’t work on the objects and materials that I put in the scene.
Is that as I suspect me making mistakes or a bug?

p.s. My english is bad so try to be patient with me.

Hey Magnus Galv -

Chances are you have set too high a roughness on your materials. You would also need to update the reflection captures when new objects are placed in the scene. You can do that by building lighting and by clicking the update captures button in the details panel of the reflection actor. (If you don’t build lighting the exact capture may have incorrect lighting in it until you do rebuild.)

Thank You
