I just checked and this script doesn't work.
I made the necessary changes to the script and Online Maps, and now it will work correctly.
Email me and I will send you the modified script and the latest version of the asset.

Thanks for reporting this.
I updated the script in that post.

Hello, I am sorry but I don't understand how this script works.

I tried different values, and nothing happens, markers disappear if the script is active, and I don't see the group marker whatever it's scale is. As soon as I change the zoom level (in or out) all my 3DMarkers disappear and they are not restored if I reset the original zoom level.

Could you please explain the parameters "Group Scale" and "Cluster To Zoom", which should be their values ?

Are you sure that this scripts works ?

Best regards, Phil

Hello.

Nope, this script is for 2D markers.
For 3D markers use Clustering3DMarkers:

In addition, Clustering scripts are much better optimized than GroupMarkersExample.

Hello, Thanks for your answer, but when I add this script I get this error :

Assets\Infinity Code\Online maps\Examples (API usage)\Clustering3DMarkers.cs(629,33): error CS0117: 'OnlineMapsUtils' does not contain a definition for 'DestroyImmediate'

I am using the 3.7.10 (last) version of OLMaps.
Best regards
