Roblox AI in Blender: How We Built the Roblox Backrooms with 3D-Agent and Claude Opus 5.5

Description and use

The team produced a Roblox Backrooms series by generating all rooms, characters, and animations in Blender using 3D-Agent and Claude Opus 5.5, eliminating manual modeling.

Problem

Creating a Roblox Backrooms series without manual modeling or rigging effort.

Outcome

The team produced a fully animated Roblox Backrooms series with no manual modeling, demonstrating that 3D-Agent can generate editable Blender geometry and integrate directly with Roblox Studio.

Workflow

• 1. Prompt 3D-Agent to build rooms, lights, and characters in Blender.
• 2. Use 3D-Agent to reconstruct a full Roblox map from a single screenshot and prompt.
• 3. Rig a character in three prompts: build parts, add bones, create a walk cycle, and export FBX.
• 4. Export FBX/OBJ to Roblox Studio via the 3D-Agent plugin or the Studio AI integration.
• 5. Optionally use the Roblox Studio AI to edit scripts, insert assets, run playtests, and publish.

Evidence

Every room, light, character and animation was built in Blender by prompting 3D-Agent.

Source

It rebuilt the whole thing in Blender: 13 cottages, seven watchtowers, a windmill and a bell tower. Real, editable geometry, not a generated shell.

Rigging is where I usually give up. Here it took three prompts: Build the character as 15 separate body parts from one reference picture. One bone per part, then a six-second walk cycle at 30 fps. Light it, render it, and export an FBX for Roblox Studio.
