Are you ready to take your Roblox game development to the next level? In this tutorial, I'm going to show you how to create a 3D viewer in Roblox using Lua programming. Let's get started!

1. Set up the environment:

First, make sure you have Roblox Studio installed on your computer. Open a new or existing project where you want to add the 3D viewer.

2. Create the 3D model:

You can either create your own 3D model using a tool like Blender or Unity, or you can use the models available in Roblox Studio.

3. Set up the GUI:

Add a ScreenGui and a TextButton to your game. This will be the interface for your 3D viewer.

4. Write the Lua script:

Open the Script Editor in Roblox Studio and write the Lua script to control the 3D viewer. You will need to use the Instance.new() function to create a Model, Part, or Union operation for your 3D viewer.

5. Set up the camera:

Use the Camera and UserInputService to allow the player to control the camera view in the 3D viewer. You can use the UserInputService:GetMouseDelta() function to detect mouse movement and update the camera accordingly.

6. Test and optimize:

Test your 3D viewer in Roblox Studio to make sure everything works as intended. You may need to tweak the camera settings and script to optimize the performance and user experience.

7. Publish and share:

Once you're happy with your 3D viewer, publish your game on the Roblox platform and share it with your friends and the community. You can also continue to refine and improve your 3D viewer based on feedback and suggestions.

By following these steps, you can create an engaging and interactive 3D viewer in your Roblox game. This will not only enhance the visual experience for players but also showcase your skills as a game developer. So, what are you waiting for?
