Roblox's New Creator Tools Explained: Build, Scene Generator and the 2D Engine Update

At RDC 2026, Roblox's annual developer conference, CEO David Baszucki announced a wave of tools built around one idea: letting far more people make a game, not just play one. The headline feature is Build, a new tab in the Roblox app that turns a written prompt into a working game with no coding and no Roblox Studio required. Alongside it came an AI-powered Scene Generator, a rebuilt engine for 2D and puzzle games, and the platform's first native support for turn-based multiplayer. Here is what each of these actually does, what Roblox has confirmed about them so far, and how they fit together.

1. RDC 2026's Building Push, in Context

RDC 2026 ran September 10-12 in San Jose and doubled as Roblox's 20th-anniversary conference. In his keynote recap, Baszucki said players spent 29 billion hours on Roblox last quarter across more than 180 countries, and framed the event's announcements around three pillars: "more play," "more building," and "more growth." The play and growth halves covered things like browser-based play and the new Roblox Wallet, which walkthroughs.net covered separately. The building half is the part aimed squarely at anyone who has ever wanted to make their own Roblox game but didn't know where to start, and it's the least covered so far.

2. Build: Making a Game With Nothing But a Text Prompt

Build is a dedicated tab in the Roblox mobile app that lets a player describe a game in plain language and get a working, publishable experience out of it — no download of Roblox Studio, no scripting. Roblox's own framing is direct: Build "lets anyone create a game through prompts and empowers more creators to create for fun, to learn, and to test out new ideas."

The tool has already been running in a public alpha in New Zealand, and Roblox shared real numbers from that test: creators have published roughly 9,000 games through Build so far, and of the people who made a game with it, 71% had never used Roblox Studio before. That second figure is the one Roblox is clearly proudest of — it's evidence the tool is reaching people who wouldn't otherwise have made anything on the platform at all.

Build's public alpha is now expanding beyond New Zealand to Serbia and Singapore, and every creator who attended RDC 2026 in person was given access as well. The expansion comes with new capabilities Roblox didn't have in the original alpha:

• A new in-app asset library to pull from while building
• Desktop access, not just mobile
• More iterative control over a project as it's built

Roblox also confirmed it's working on connecting Build directly to Roblox Studio, so a creator could start a game on their phone with a prompt, then open the same project in Studio for deeper editing — rather than the two staying as separate, disconnected tools. Build already lets creators check analytics and turn on monetization for a published game from inside the app, and Roblox says the ability to launch ads for a game directly from a phone is coming soon.

3. Scene Generator: AI That Sketches a Layout Before You Touch Studio

Sitting underneath Build is the technology Roblox calls AI Scene Generation. The company describes the upcoming feature — branded Scene Generator — as "prompt-to-scene functionality across both Build and Studio, with greater creator control available in Studio." In practice, a creator provides a text prompt and a reference image, and the system generates a fully functional 3D layout that can then be refined by hand.

Roblox has not given Scene Generator a firm release date beyond "coming later this year," so treat the exact timing as unconfirmed for now. What is confirmed is the split in control: Build is positioned as the fast, mobile-first way to get a scene started, while Studio remains where creators get the finer-grained tools to actually finish a game.

4. Roblox Is Finally Built for 2D and Puzzle Games

A separate part of the "more building" announcements addressed a long-standing gap: Roblox's engine has always been built around 3D multiplayer worlds, even though some of the most-played games anywhere are simple 2D and puzzle titles. Roblox is now adding engine features specifically for that genre, including:

• A new orthographic camera mode, useful for flat, top-down or side-scrolling games
• Animated image containers
• Direct sprite-sheet import, so 2D animations don't have to be rebuilt frame-by-frame inside Studio from scratch
• New UI features — blur, text shadows and improved gradients — aimed at making 2D interfaces look less like a 3D engine wearing a flat skin

5. Turn-Based Multiplayer Gets Native Support

Alongside the 2D engine work, Roblox confirmed it's expanding support for turn-based, asynchronous multiplayer games — think card games, board games or word games where players don't need to be online at the same moment. A new notification system will alert a player when it's their turn to move. Roblox gave a concrete timeline for this one: it arrives in Studio Beta in October 2026, with a full release targeted by the end of the year.

6. How the Building Announcements Connect to the Rest of RDC 2026

None of this happened in isolation. The same week, Roblox also ran its 2026 Innovation Awards, celebrating the kinds of experiences creators are already shipping, and published its Fall Games Preview lineup of ten new titles arriving through October — several of which come out of the same creator programs, like Incubator, that Build and Scene Generator are meant to feed into going forward. The building tools are also arriving during Roblox's 20th-anniversary stretch, which is separately being marked by The Hunt: Roblox 20, a platform-wide event running through September 28.

Roblox also used the keynote to announce a new podcast, Made on Roblox, profiling the creators behind popular games; its first episode, about the breakout hit 99 Nights in the Forest, is due later this month.

7. What This Means If You Want to Try Making a Game

For players who have never touched Roblox Studio, Build is currently the easiest on-ramp Roblox has ever offered — but its public alpha is still limited to New Zealand, Serbia and Singapore, plus anyone who attended RDC 2026 in person. Everyone else will need to wait for a wider rollout, which Roblox hasn't dated yet. If you're outside those regions, the practical options right now are still Roblox Studio directly, or simply waiting: Roblox's stated goal is to connect Build and Studio into one continuous path from a five-second prompt to a fully shipped game, and the 2D engine and turn-based support arriving through the rest of 2026 will apply to Studio projects regardless of whether Build was involved at the start.

Quick recap

• Build: prompt-based game creation in the Roblox app; ~9,000 games published in alpha, 71% of creators were Studio first-timers; expanding to Serbia and Singapore
• Scene Generator: turns a text prompt plus reference image into a 3D layout across Build and Studio; coming later in 2026
• 2D/puzzle engine: orthographic camera, sprite-sheet import, animated image containers, new UI effects — available now for Studio creators
• Turn-based multiplayer: native "your turn" notifications, hitting Studio Beta in October 2026 and full release by year's end
