Are you a game developer on Roblox looking to add a cool 3D viewer to your game? In this tutorial, we'll walk you through the process of creating a 3D viewer using Lua scripting. Let's get started!

Step 1: Set Up the Environment

Before we begin, make sure you have Roblox Studio installed on your computer. Open Roblox Studio and create a new place for your 3D viewer project.

Step 2: Create the 3D Model

Next, you'll need to create the 3D model that you want to display in your viewer. You can use modeling software such as Blender or Roblox Studio's built-in modeling tools to create your 3D model.

Step 3: Scripting

Now it's time to start scripting the 3D viewer. In Roblox, scripting is done using the Lua programming language. Create a new Script inside Roblox Studio and start writing the code for your 3D viewer.

Here's a basic example of how you can set up a simple 3D viewer script:

```lua

local camera = game.Workspace.CurrentCamera

local model = -- insert the path to your 3D model here

camera.CameraType = Enum.CameraType.Scriptable

camera.CFrame = model.CFrame

```

In this example, we're setting the camera's type to 'Scriptable' and then setting its position to the same as the 3D model's position. You can customize the script further to add user controls, animations, and more.

Step 4: Test and Refine

Once you've written the script, it's time to test your 3D viewer in Roblox Studio. Make sure the camera behaves as expected and that the 3D model is displayed correctly. You may need to refine your script and make adjustments to get the desired result.

Step 5: Publish and Share

After you've finished creating and testing your 3D viewer, you can publish your game on Roblox and share it with the community. Players can then interact with your 3D viewer and admire your awesome 3D model!

In conclusion, creating a 3D viewer in Roblox is a fun and rewarding project for game developers. By following this step-by-step guide and experimenting with Lua scripting, you can bring your 3D models to life and create an immersive experience for your players. We hope this tutorial has been helpful, and we can't wait to see the amazing 3D viewers you create in Roblox! Happy scripting!
