How do I get my unit selection decal to appear on the floor below my unit?

I’m writing a rts game and having trouble showing a circle under selected units. In unity I had accomplished this by showing and hiding a decal attached to the unit prefab, but it seems that the decal component for blue prints wants to show up on other compinents, not the ground under them . Any advice is appreciated.

It should work if you decrease the scale of the decal in Z axis. Test it in a level and make it as thin as it goes before it starts to vanish.

I fixed my issue. It turns out I had the decal rotated in such a way that it just wasn’t showing up.

hey i was having the same issue and i solve it here
