here is a very simple scene, loading only 40 minutes at a good quality of 3000 pixels. After all, the rendering time mainly depends on the weight of the models, not on the hemispheres. There are as many of them here as in other projects where the download took 12-25 hours

the file of this scene is here https://www.mediafire.com/file/9qo9kjfl ... .sh3d/file
