Creating 3D models for Roblox is a fun way to build your own games, characters, items, or environments — but it does come with specific rules and tools.
Here’s a complete guide on:
🛠️ How to Make 3D Models for Roblox
🔰 Tools You'll Need
Tool Purpose Notes
Roblox Studio Main platform for creating games & models Free, official tool
Blender (Optional) Create advanced custom 3D models Export to .fbx
Paint3D / Tinkercad Simple models (for beginners) Must export as .obj/.fbx
🔷 Option 1: Make Models Inside Roblox Studio (Easiest)
Step-by-Step:
1. Open Roblox Studio
Download it from: https://create.roblox.com
Login with your Roblox account.
2. Create a New Project
Choose a baseplate or template (like “Obby”, “City”)
3. Use the Part Tool
Use the "Model" tab → Click Part
You can add:
Block
Sphere
Wedge
Cylinder
Move, scale, and rotate using the tools at the top.
4. Combine Parts
Build complex shapes by combining basic parts (called "Union")
Use Model → Union to merge parts
Use Negate to subtract parts (like holes)
5. Color & Material
Use Properties panel to change color, transparency, reflectance
Choose materials like metal, wood, plastic, neon, etc.
6. Group and Name
Select all parts → Right-click → Group
Name it clearly, e.g. BananaModel
7. Save as Model
Right-click your model → Save to Roblox (or Export Selection to local file)
You can reuse it later or share it via Toolbox
🧊 Option 2: Import Custom 3D Models (From Blender or Others)
This is used for more detailed models (like characters, weapons, props).
Step-by-Step:
1. Create Model in Blender
Model using low-poly style (Roblox is optimized for performance)
Avoid too many vertices
Use simple textures (no PBR materials)
2. Export as .FBX
File → Export → FBX (.fbx)
In export settings:
Check “Selected Objects”
Apply transforms
3. Import into Roblox Studio
Open Studio
Go to Asset Manager → Right-click → Import
Select your .fbx file
Studio will convert it to a usable mesh
4. Apply Textures (if any)
Add texture image files separately
Use the SurfaceAppearance object for newer materials
5. Add Collision
For physics to work, add a CollisionFidelity setting
You can also manually add invisible parts for hitboxes
🎮 Make It Playable (If It's a Game Object)
Add Scripts if the model should do something (like move, disappear, etc.)
Insert into the StarterPack or workspace depending on use
⚠️ Important Guidelines for Roblox Models
Rule Why it Matters
Max 10,000 triangles (prefer < 2,000) Performance issues
No inappropriate shapes/textures Follows Roblox TOS
No animations on imported MeshParts (must be rigged separately) Use Blender + bones for this
Use Anchored or Welded parts Avoid physics bugs
📦 Uploading Your Model to Toolbox (Optional)
Select model → File → Publish to Roblox as Model
Add description, tags
Set permissions: Public or Private
It can now be reused in other games
