A coupla years ago I did an animation of the Moon revolving around the earth using a terrain in a similar manner as your soccer net. I tried to recreate it here without the textures for the spheres. I grouped the moon and the terrain together and spun them around the earth. Because the grid texture was set to World Space, it didn't rotate. The moon appeared to cause a dimple in the grid as it moved. The effect was very convincing. Steve S.
