This model, based off of my original concept design, took a total of 5 weeks to create. I had a lot of fun creating her, and have learnt a lot due to the challenges of an underwater character. I also used Substance Designer for the first time to create the scales for the tail.
Thank you so much to both Adam and Bailey who allowed me to use their iridescent shader on the tail created in UE4. I've linked their portfolios below:
