Simple VR Scene
This topic walks through building a beginner VR scene. The example creates a small virtual room where a user can look around and pick up a virtual cup.
Step 1: Set Up the Environment
Add a floor, walls, and basic lighting inside the game engine. Keep the room small at first, since a smaller space is easier to test and debug than a large open world.
Step 2: Add the VR Camera Rig
A camera rig links the headset's real movement to the virtual camera inside the scene. When the user turns their head in real life, the rig moves the virtual camera to match, creating the correct view for each eye.
Step 3: Add Hand Controllers
Attach virtual hand models to the positions tracked by the physical controllers. As the user moves their real hands, the virtual hands move in the same way inside the scene.

Step 4: Add an Interactive Object
Place a virtual cup on a table inside the room and attach a script that lets the user grab it when their hand controller touches it and the grip button is pressed. Releasing the button drops the cup back into the scene.
Step 5: Test Comfort and Movement
Check whether looking around the room feels smooth and whether the hand tracking matches real hand movement closely. Add a teleportation system if the room grows larger than the physical play space available to the user.
Simple Explanation
Think of the camera rig like a pair of glasses glued to your actual head position. Wherever your head goes, the glasses go too, and whatever the glasses see becomes the picture shown inside the headset.
Common Beginner Mistakes
New developers often forget to scale the room to real-world size, which makes objects look too large or too small. Another common mistake sets the camera height incorrectly, which makes the user feel like a giant or a small child inside the scene.
Why This Project Matters
This basic room-and-cup scene teaches the exact skills needed for larger VR projects, including training simulations, virtual showrooms, and interactive games.
