Right now there is a small problem, even with 32 render distance it is not possible to observe a large scale thermonuclear explosion from a safe distance, such as a custom nuke with thermonuclear power 400 and obviously anything bigger. If its possible to do this, my idea would be to make flash + mushroom cloud render at (render distance*3) so at 16 render distance you would be able to see nukes from 768 blocks away
