Hi,

I'm working on a simple plugin that should display a triangle at the selected celestial body in map (tracking station) view.

I think I'm OK with the Start(), Awake() and Update() callbacks, but the mesh is not displayed.

Could anyone comment?

        {

            Debug.LogError("KspCelestialOverlay Awake scene=" + scene.ToString() + " " + Time.time.ToString("0.0000"));
            // we do it in the trackstation only
            if (scene != GameScenes.TRACKSTATION)

The saga continues. Now with a sphere...

Why doesn't it appear?

Hmmmm... You sure 1500 is big enough to cover the body (it should, but you can't be too careful)? You haven't assigned a material or renderer either. Check your logs. You probably have a few null-reference exceptions from those.
