Earth's orbit night/day composite cycles

I decided to brush up on render layers and compositng to make a short earth test. There’s 3 render layers, earth with day texture, earth with night texture (this has an emission mask) and a diffuse layer. The diffuse layer is used in compositing as a mask between the two.

I’ll try to come up with another series of shots that’s a bit more dramatic and artsy. The compositing nodes are below.

nice…well done

Thanks mart, it was just a little couple hour project for fun. I don’t think it really counts as a test of anything though.
