How to make circle projectors look "normal"?

Unity Engine
1

I have an RTS-style game and want to have an effect when I select a unit, that for example shows the range how long he can throw. However, when the ground isn’t flat, it looks really weird.

Is there any way to make this work better, or anything else than a projector, which indeed looks great on flat or nearly flat surfaces.

Here’s an image showing what I mean. It’s kinda hard to see, but the left part of the image is a hill.

Use cylindrical rather than spherical

Enable the orthographic option or pull it up far enough. Here you project at a very sharp angle which gives you that result.

Ah great, that worked by decreasing the field of view, and putting it higher up, but ortographic was even simpler. Thanks a lot!
