As a 3d designer, I completely support the use of ai to help with visualizing concepts.
It is super efficient and helps the process become easier when you suck at making visuals for ideas.
EPIC TALKS ABOUT FORTNITE's CONCEPT ART PROCESS (Skins, POIs, etc..)
• Artists still start with original ideas & sketches in Photoshop, Blender, hand-drawing, etc..
• AI tools are used to iterate and test ideas faster
• Examples shown include: different POI lighting, style swaps, meteor showers, colors, render passes, etc.
• Artists fix mistakes, remove unwanted details, and keep creative control
