/3/ - 3DCG

>>976641
I goatse'd a planet once, seems like the same thing.
All I did was make a divot into the mesh using proportional editing, then masked it off to blend between the planet and the grid. Though you wouldn't need to do the masking step. Then you just animate the coordinates of the grid.
Here's a blend file you can use as an example. I've done what I could to explain the material nodes in a (hopefully) obvious fashion. Maybe it'll help.
