Hi there, I was able to bring the Moon level into my project, however I am having issues navigating to the surface of the moon. I added it as a level under CesiumGeoreference, but I am unable to explore it and get up close, place objects on it. Any suggestions? Is there a better way to add moon terrain into the project? It is not showing up in the “Quick Add” window. Thank you!

Hi @VRTravelExpo,

Have you created a custom ellipsoid for your project? This is a necessary step for rendering the moon, as it greatly differs in dimensions from the Earth.

In the plugin folder we have a `WGS84` asset that specifies the radii of the WGS84 ellipsoid. You can make a copy and replace the radii with that of the moon, and it should behave better. But of course, let us know if you run into any issues along the way 😄

It would be helpful if this showed up on the Quick Add window! I’ve added a Github issue here with the suggestion:

> This option should also automatically create an ellipsoid for the moon for the t…ileset to use. (Or actually, maybe we should supply the ellipsoid ourselves in the plugin contents?

Where can I find this plugin folder? Also, is there any repo or documentation on how to get started with Moon Terrain in Unity?

To create a Moon ellipsoid in Cesium for Unity:

1. Open the Project browser and navigate to a suitable folder within your project.
2. Right-click and choose Create → Cesium → Ellipsoid.
3. Rename the created `New Cesium Ellipsoid` to `Moon` or similar.
4. In the Inspector, change the X,Y, and Z radii to `1737400.0`

5. On your `CesiumGeoreference` object, select your new ellipsoid for the `Ellipsoid Override` property.
