Epic Games has finally addressed what it's been doing with generative AI in game development, pulling back the curtain in a newly released video that shows exactly where artificial intelligence fits into the creation of Fortnite's character skins and in-game locations.
The video, posted to the Unreal Engine YouTube channel, walks through the design process for a new character skin from start to finish. Human artists begin with hand-drawn sketches, then use AI prompts to accelerate the transition into 3D model aesthetics. The crucial distinction Epic makes is that AI enters the workflow after initial ideation, not at the beginning. Artists are still driving the creative direction, with the company positioning AI as a tool to handle repetitive stages and free up designer time for refinement.
What the footage also reveals, however, is that AI generation introduces its own problems. The system creates unwanted details and errors that require another human review pass to catch and fix. An Epic Games employee featured in the video frames the relationship plainly: "The design is king, AI can generate generic stuff all day, but that's not what we're doing here. It just skips ahead in the timeline so [the artist] can focus on honing in on the design and crafting it exactly how he wants it to be."
The location design process follows a similar rhythm. Concept artists sketch scenes in Photoshop, pass them to 3D modelling in Blender, then use AI to explore variations like different lighting conditions or environmental damage. According to Epic, multiple rounds of human review happen throughout before anything ships in the actual game.
The company's openness comes after months of fan speculation sparked by noticeable oddities in existing assets. A poster showing a nine-toed character in a hammock drew particular scrutiny online, with players questioning whether AI had been involved. Epic had stayed silent on those inquiries until now.
This acknowledgment doesn't mean AI is generating characters or locations wholesale. Instead, it's being used to accelerate iterative stages of work that artists would otherwise handle manually. Epic says teams can now revise faster and explore more design directions, with the catch that those continual reviews must catch whatever the AI system gets wrong.
The studio has prior experience with controversial AI applications in gaming. Epic previously used generative speech technology to recreate James Earl Jones' iconic Darth Vader voice for Fortnite, a move Disney approved. The feature still ignited debate among players who immediately began having the digital Vader voice lines that contradicted the character.
Epic's leadership has already signaled that AI adoption in game development is inevitable and widespread enough to make warning labels pointless. Tim Sweeney, the company's CEO, argued last year that Steam's AI Generated Content disclosure tag will become meaningless as the technology becomes standard across the industry. "The AI tag is relevant to art exhibits for authorship disclosure, and to digital content licensing marketplaces where buyers need to understand the rights situation," Sweeney wrote on social media. "It makes no sense for game stores, where AI will be involved in nearly all future production."
Author Emily Chen: "Epic's being transparent about process, but the real question is whether human review actually catches everything before millions see it in-game."
