Sérgio Merêces shares the entire creation process of this scene. For inspiration, he starts with an open source AI tool that I hadn't seen before: ComfyUI, a node-based GUI for Stable Diffusion. He then moves to Blender to sculpt the fish, texture it and create the environment.
I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.
