Unreal Studio Product Viewer Template

The Product Viewer Template provides a ready-to-use interactive product visualization experience for desktop and VR devices. You can interact with the models, move pieces around, make them transparent, and get around the scene using built-in navigation controls.

All of the interaction and navigation controls are provided by Blueprints in the Project, so you can customize them, learn from them, or even copy them into your own Projects.

This page describes everything you need to know to get started with the Product Viewer template, and to use it for your own models.

Playing the Project

The Product Viewer comes with some built-in models, so that you can try out working your new Project right away in the Editor, as soon as you create it.


If you want to test out the Project in VR, see Test in VR in the Editor below.

The Product Viewer offers different navigation modes for desktop and VR viewing.

Desktop Orbit Mode (Mouse Navigation)

Orbit mode is the default navigation mode for desktop viewing. In this mode, the camera is always centered around a particular spot in the 3D world.



Rotate around the current point of interest

Right-click and drag

Change the camera's point of interest to a new location, remaining at the current zoom level


Change the camera's point of interest to a new location, zooming to fit the new object in the viewport


Pan the camera sideways, up, or down

Middle-click and drag

Zoom in or out on the current point of interest

Use the mouse wheel

In order for an object in the scene to be selectable as a point of interest in Orbit Mode, it must be set as either an interactive object or a teleportable surface. See Adding Your Own Content below.

Desktop Flying Mode (Keyboard Navigation)

In Flying mode navigation, you can move the camera around the scene using your keyboard.



Move the camera forward and back along its facing axis

W and S

Move the camera left and right perpendicular to its facing axis

A and D

Move the camera up and down along the world Z axis

E and Q

Rotate the camera to a new facing direction

Right-click and drag

While in Flying mode, the interaction controls for selecting objects, moving objects and controlling X-Ray are disabled.

To switch the Product Viewer to use Flying mode:

  1. In the World Outliner panel, find and select the ProductViewer_Collector Actor.
    Select the Product Viewer Collector

  2. In the Details panel, find the Product Viewer section, and change the Navigation Mode setting to FlyingMode.
    Flying Mode settings

  3. By default, while in Flying mode you can pass through all objects in the scene, even those with collision meshes set up for them. If you want to prevent the camera from passing through objects with collision meshes, also clear the No Collision on Flying Mode checkbox.

VR Teleport Mode

When you run the Product Viewer in VR, your viewpoint on the scene is controlled by your headset and your position in the VR scene. If you need to move to a different position in the scene, you can use the left controller to teleport yourself.

  1. Click the left-hand controller thumbstick button. You'll see a target marker superimposed on the ground:

  2. Move the left-hand controller around in space until the target marker appears at the location you want to move in the VR scene.

  3. As you push the left-hand controller thumbstick back and forth, the target marker rotates to show the facing direction you'll have after you teleport.

  4. When you have the target marker where you want it, and pointed in the right direction, release the thumbstick button.

By default, you can only teleport on the floor. When you add your own content, you can specify exactly what surfaces you can teleport to. See Adding Your Own Content below.

Selecting and Moving Objects

You can select and move any movable object in the scene that has been identified as interactive.

For instructions on defining what objects are interactive, see Adding Your Own Content below.




Move an object to a new position in the scene

Left-click and drag the object

Snap an object back to its original position

Right-click the object


In VR, you'll use the right-hand controller to select and move objects.



Highlight an object

Point the laser selector from the right-hand controller at the object

Grab an object

Highlight the object, then press the right-hand trigger button

Move an object

Grab the object, then move the right-hand controller in real-world space

Release an object at its new position

Release the right-hand trigger button

Snap an object back to its starting position

Highlight the object, then press the grip button on the right-hand controller

Using X-ray Mode

You can make any interactive object in the Product Viewer use X-ray mode. While in X-ray mode, the object is nearly transparent, and temporarily becomes non-interactive. This lets you see and interact with the objects behind it.

X-ray Off

X-ray On

You can choose the following options from the X-ray menu:

Menu item


Apply X-ray

Switches the highlighted object to use X-ray mode

Isolate X-ray

Switches all other objects to X-ray mode, but leaves the highlighted object opaque

Clear All X-ray

Resets all objects in the scene to their original Material


To open the X-ray menu, press the space bar while hovering over an interactive object.


To open the X-ray menu in VR and select an option, push the right-hand controller thumbstick forward or back. Press the thumbstick button to confirm the current choice.

Test in VR in the Editor

When you launch a cooked or standalone version of the Product Viewer with VR set up on your computer, you'll be able to choose whether to launch using desktop controls or VR controls in the splash screen:

However, if you want to test the Product Viewer in the Editor using VR controls, you need to follow these steps:

  1. In the World Outliner panel, find and select the ProductViewer_Collector Actor.
    Select the Product Viewer Collector

  2. In the Details panel, find the Product Viewer section, and select the VR Preview option.

  3. To launch the preview, use the drop-down arrow next to the Play button in the Toolbar to select  VR Preview.

Don't forget to turn this setting back off before you cook your game! If you don't, the resulting package will not work as you expect.

Adding Your Own Content

Once you've seen how the Product Viewer works using the built-in content, you'll want to bring in your own models and get them working in the experience.

  1. Import your content into your Project. You can use any method to get your content into the Project: import as FBX, import using Datasmith , add from the Marketplace or from another feature or content pack, etc.

  2. Add the models you want to explore into the default ProductViewer/Levels/ProductViewer level.

  3. Make sure all of the Static Mesh Actors that you want to be able to move around at runtime have their Mobility option set to Movable in the Details panel:

  4. In the World Outliner panel, find and select the ProductViewer_Collector Actor.
    Select the Product Viewer Collector

  5. In the Details panel, find the Product Viewer section.
    Product Viewer interactive root and teleport surface root

The ProductViewer_Collector Actor contains two key settings, shown above:

  • The Interactive Root is a list of objects in the scene that the player can interact with.

  • The Teleport Surface Root is a list of objects in the scene that the player can teleport to in VR mode.

You can add each of your own models that you want the player to be able to interact with or teleport to into these lists.

If you've used Datasmith to import your content, the Datasmith Scene Actor in your Level will already be the parent of all your imported Static Mesh Actors. Add a new entry in the Interactive Root list, set it to refer to the Datasmith Scene Actor, and all of its children will automatically become interactive.

Alternatively, you can parent the Static Mesh Actors that you want to become interactive or teleportable to another Actor that is already in the list you want. For example, by default, the ProductViewer_Collector has only one entry in its Interactive Root list: an Actor named Interactive_Root. If you find that Actor in the World Outliner, you'll see that it is the parent of many child Actors that represent the gears, the ball, and the flashlight:

Interactive_Root Actor

Every child of an Actor in the Interactive Root list is automatically marked as interactive as well. So, all you need to do is re-parent your own models under the existing Interactive_Root Actor. You can do this by dragging and dropping them in the World Outliner.

Adding the Product Viewer to a Different Project

If you have your content in another Project, you can add the navigation and interaction controls from the Product Viewer into your other Project.

  1. Open the Project and Level you want to enhance with the Product Viewer controls.

  2. In the Content Browser, choose Add New > Add Feature or Content Pack.

  3. In the Add Content to the Project window, open the Unreal Studio Feature tab. Click the Product Viewer thumbnail, then click + Add to Project.

  4. Click the X to close the Add Content to the Project window.

  5. In your Content Browser, find the ProductViewer/Blueprints/ProductViewer_Collector Blueprint Actor, and drag and drop it into the Level Viewport.

  6. Finally, set up the ProductViewer_Collector Actor in your Level as instructed under Adding Your Own Content above.
