Some time ago I made this jellyfish to test the potential of animation in Keyshot, and personally I find it very satisfying.
Thanks to the bridge between 3DS Max and Keyshot it's really easy to import complex projects like this, where almost everything has been done in physical simulation.
Equally interesting was the study of advanced materials in Keyshot (it's simply a single material).
Obviously this jellyfish is invented, it has six beautiful extremely bioluminescent gonads, I called him "Ghost of the sea".
