Roblox exec Anupam Singh showed off the new Roblox Reality graphics at RDC 2026 today.
It’s a video world model that layers over the Roblox Engine to provide photorealistic environmental changes (e.g., weather, lighting) without altering underlying code. Autonomous NPCs: New technology to add hundreds of intelligent, non-playing characters to worlds for testing and engagement.
Without changing the code, Singh enables Roblox Reality and adds the Northern Lights to the game. And boom, in an instant, the Northern Lights show up in the background sky of the game. Nothing else changes.
“We didn’t change the code. We didn’t change objects. I can literally take a reference image here, and I can make it sunny, and I can continue playing the game. By the way, I can continue going up and down inside the game and turn around. You can see the mountains, the cloud, everything changes,” Singh said.
Singh noted that creating water is technically difficult, and even harder is to capture the transition from water droplets to fog and changing the weather. When someone walks in the water, you can see the water parting in the water puddles.
“It’s taken us years in technology to be able to send those water droplets into the ferris wheel, and you see how the water drops from the ferris wheel cabins,” he said.
Then he changed it back to sunny weather.
Singh said, “We believe that Roblox Reality will give players and creators the ability to change environments.”
