I find bubbles to be quite charming to look at, especially the way the soapy surface reflects a vibrant array of swirly color. I wanted to try and create this myself, and to some degree I think I accomplished this. During the process of creating the texture, I was reminded of the cartoon TV show SpongeBob SquarePants. They had a few episodes air with a character named Bubble Buddy, and I though it could be both fun and challenging to try and make him in a more realistic perspective. I quite enjoyed playing around with Unreal's material nodes and learned a lot from it.
