Glossary
Plain-English definitions for the Roblox, AI, and HyperDevs terms used throughout these docs.
HyperDevs
A Windows desktop app for AI-powered Roblox game development. It bundles image generation, image-to-3D, mesh optimization, Luau code generation, and one-click Studio import into one app.
Hyper 30
HyperDevs’ built-in cloud AI model — one built-in 80B Qwen3-Coder-Next MoE served from the HyperDevs cloud proxy (despite the name, it’s a single model, not 30). It needs no API key — you sign in and generate immediately. It’s credit-billed, with a free tier included.
BYOK (Bring Your Own Key)
Using your own AI provider API key (Gemini, Claude, OpenAI, z.ai, or Ollama) instead of the built-in Hyper 30 model. In HyperDevs, BYOK keys are stored locally and never sent to HyperDevs servers.
MCP (Model Context Protocol)
An open protocol that lets an AI model call external tools and read external data. In Roblox, an MCP bridge (a Studio plugin + local server) lets AI read your DataModel and make live edits to your game.
MCP tools
The individual actions an MCP server exposes to the AI (e.g. “list instances,” “create a Part,” “write a script”). HyperDevs exposes 85+ such tools for Roblox Studio.
EditableMesh
A Roblox beta feature/API that lets a script create and modify a mesh from data at runtime. It’s what enables one-click import of an AI-generated mesh into a live Studio session. Enable it in Studio under File → Beta Features.
EditableImage
A Roblox API (companion to EditableMesh) for creating and modifying image textures at runtime, used to apply AI-generated textures to meshes.
MeshPart
The Roblox instance type that holds an imported 3D model. Custom 3D assets in Roblox are MeshParts, loaded from FBX, OBJ, or GLB files.
Text-to-image
Generating an image from a text description using a diffusion model (e.g. Flux). It’s the first step in the text-to-3D pipeline.
Image-to-3D
Reconstructing a 3D mesh from a single 2D image using models like TripoSR, Tripo3D, Trellis, Rodin, or Hunyuan3D. The second step in the text-to-3D pipeline.
Diffusion model
A class of AI model that generates images by gradually denoising random pixels. Flux is a diffusion model used for text-to-image.
Decimation
Reducing the triangle count of a 3D mesh while preserving its shape. Required because AI-generated meshes arrive far denser than Roblox allows.
Triangle / polygon budget
The triangle count a mesh must stay under for Roblox. Aim for under ~10,000 triangles per mesh (often 2,000–4,000 for repeated objects) to keep frame rates healthy, especially on mobile.
Low-poly
A mesh built from relatively few polygons. Low-poly, stylized geometry survives optimization and performs better in Roblox than dense photorealistic meshes.
Rigging
Adding a skeleton to a 3D model so it can be animated. For characters, image-to-rig tools (e.g. Meshy) produce rigged models better than generic text-to-3D.
UV map
The mapping between a 3D mesh’s surface and a 2D texture image. Needed to paint or apply textures correctly.
FBX
A 3D file format that supports meshes, materials, textures, rigs, and animations. It’s the most reliable format for importing models into Roblox Studio.
GLB / glTF
A modern 3D file format increasingly supported by Roblox, commonly produced by AI model generators.
Ollama
Software for running large language models locally on your own machine. HyperDevs supports Ollama for fully offline, free AI.
Flux
A family of text-to-image diffusion models (Flux Schnell, Dev, Pro). HyperDevs uses Flux for image generation.
