Hello again.
I have modified the example of “GlobeMaterialsTutorialListing03” to try to put the moon in the position of the camera (or rather, in front of her) then to replace it with a new camera that the hovercontroller does not use.
But I supposed what the moon would remain in the center of the view but it is not like that. It moves of erratic form and I do not know why
This one is the file modified “GlobeMaterialsTutorialListingBase”:
