This animated logo was a bit tricky to create in After Effects. To make the mountains, I had to use the Freeform plug-in effect with a color and displacement map that's around three times the size of the main composition. I did this so I have enough mountain space to maneuver the camera around in. Then I added a bunch of texture images to the displacement map to get the little rocky formations. This was followed by tinkering around with 3D mesh of Freeform to create the actual mountain.
