Hi there @BartPal,
Hope you’re well and having a wonderful week so far 
Wow, what a beautiful environment. The transparency of the water and the dreaminess of the lighting is just breathtaking. It somehow manages to feel natural and futuristic at the same time. Brilliantly done!
Thanks so much for taking the time to share it with us here on the forums. If you don’t mind answering, what was the biggest challenge when creating this environment?
