Virtual Reality quick start guide

Learn the basics of using Modeler in VR so that you can jump right in.
We recommend reading this guide if you have already used other creative VR applications or prefer to learn by exploring rather than reading documentation. Below, we'll introduce the foundational concepts of Modeler. M
ost of the topics below are covered in more detail elsewhere in the documentation, if you have questions about any topic follow the links to learn more.

By default, the Oculus app prevents applications from being opened if they haven't been reviewed by Oculus. In order to run Modeler, you will need to allow Oculus to run content from external sources. You can do this in the menu of the Oculus desktop application. For full instructions on enabling external content, refer to the Oculus documentation here.

Note: When using Air Link this setting has to be enabled in the desktop app, instead of the Quest's settings.

Modeler can only be used on Quest headsets when connected to a computer via Air Link or cable.

Improve VR comfort

Your headset shouldn't get in the way of sculpting and creating with Modeler. It's worth checking the following settings for your headset to ensure the best experience:

  • Refresh rate: A higher refresh rate decrease the chances of motion sickness and improves long term comfort.
  • Straps: Overtight straps can cause headaches and discomfort, while loose straps can result unclear visuals and the need to constantly readjust the headset. At the start of a sculpting session, spend a few minutes to ensure your headset sits snugly.
    • Most major headsets have third party alternatives that can be used instead of the straps. If you find that no matter what you try the headset does not feel comfortable, third party straps may help bring new life to your VR experience.
  • Faceplate: The soft surface between your face and the headset is referred to as the faceplate. On some headsets the faceplate uses a material that can become uncomfortable over time. Third party faceplates and covers are available for all major VR headsets, and can drastically improve your VR experience.
  • Controller straps: Even though Modeler isn't a highly active experience, we recommend using the controller straps. Not only does this reduce the chance of injury or damaging your property, but during long sculpting sessions it's useful to be able to release the controllers without searching for a place to put them down.
  • Maximize your available area: Sculpting in a larger space is safer and decreases the risks of hitting furniture or valuables with a controller. If you can, try to move furniture and fragile objects away from the VR space so you can focus on sculpting instead of avoiding a disaster.

Although it is not officially supported, it is possible to use Modeler on non-Oculus hardware with Revive. Find out how to configure Revive for Modeler here.


Controls

The controller in your dominant hand is referred to as the tool hand, while the controller in your non-dominant hand is referred to as the support hand. The diagram below shows the standard right-handed controls.


You can learn more about controls in VR here.

How do I swap the controllers?

The controllers default to a right-handed layout, however you can change this in the preferences:

  • Use File > Preferences, or shortcut Ctrl + K to open the preferences.
  • Select Spatial from the left side of the Preferences window.
  • Toggle handedness on to use left-handed controls.

Move in 3D

By using Modeler in VR, you exist inside your scene.

There are two ways to navigate the scene:

  1. Physically move your body through the scene.
  2. Use the controller grips to move the scene around you.

Unfortunately learning how to move your body is beyond the scope of this guide, but we'll cover how to use the grips below.

  • Press and hold one of the grips, then move the controller to move the scene. 
  • Press and hold both grips at the same time, then move the controllers towards or away from each other to zoom in or out.

By combining the grip movements, you can navigate the scene very quickly, even while seated.

The Palette 

The Palette is where you can access most of Modeler's tools, actions, and other functionality. To open the Palette, use the lower button on the support hand. 

To interact with the Palette, point your tool hand at the Palette to highlight controls, and pull the tool hand trigger to use buttons and sliders.

Learn more about the Palette here, or explore Modeler's interface here.

Tools

Modeler's tools can be accessed through the Tool panel in the Palette. Most of Modelers tools can be accessed directly from the Tool panel, however some can only be accessed by selecting another tool first.

For example, if you select the Warp tool, you can then select the Elastic tool just above the tool parameters.

Tool parameters allow you to modify the brush and how the tool works.

Learn more about specific tools here, or learn more about the brush here.

Scope

Unlike most 3D software, Modeler doesn't display a scene hierarchy or outliner. This is because Modeler's powerful instancing functionality results in large hierarchies that are often more confusing than helpful. 

Instead of relying on a cumbersome scene hierarchy, Modeler uses Scope and Scoping

Your current scope determines what you can modify in the scene. For example, if you are scoped into a layer, your tools and actions can only modify that layer. If you scope out so that all the layers and groups in your scene are in scope, then your tools and actions can modify any object in your scene.

You control your scope using the joystick on the support hand. To scope into a layer, point your tool hand at the layer and move the support hand joystick up. To scope out of your current layer or group, move the support hand joystick down.

Learn more about scope here.

Actions

Actions refer to the set of functions that allow you to manage layers in your scene. A few examples of common actions are:

  • Creating a new layer.
  • Grouping layers.
  • Increasing layer resolution.
  • Hiding layers.

Actions are available in the right click Action Menu on Desktop, but they are accessed slightly differently in VR. To view currently available actions:

  1. Open the palette with the top button on the support hand.
  2. Swipe right with the tool hand joystick.
