I would like to present my completed project of planet Earth. All created in Blender BGE 279. I have re-created the Earth, clouds and atmosphere in the overall project Sol System V1. All lighting conditions are now dynamically calculated and displayed appropriately. Also the landscape is now very plastic, including the coasts. The clouds are still a little static, but the simulation of clouds is an issue in itself, which I will not tackle until the next few months. The next planets are now gradually following.
Here is my video. I am happy about all the comments.
Trip to Earth from outer space. TIP: Switch the video to HD. This is the best result.
