What is the Unity plugin?

In ProtoPie Connect, you can embed Unity layers using Custom Layer Integrations. The Unity plugin bridges ProtoPie and Unity, allowing for smooth communication and an interactive design experience.

Is the Unity plugin free to use?

The Unity plugin is free to download and install for all ProtoPie plans. However, integrating Unity interactivity within Connect is a feature exclusively available to our Connect Enterprise users. Please refer to the ProtoPie Connect tiers feature table to understand the features included in each tier.

Integrating Unity layers in Stage Views

ProtoPie Connect's Stage Views feature enables you to integrate ProtoPie prototypes with diverse custom layers, including web embeds, live cameras, and Unity projects. This integration enhances the user testing experience and renders your designs more dynamic.

With Connect Core, you can integrate one Unity layer for all Stages, while Connect Enterprise has no limit to the number of Unity layers you can add.

How to configure Unity layers

Adding Unity scenes to your project is straightforward with the Unity layer. Here's how:

  1. Build the Unity project: Use WebGL as the target platform and archive the build folder or files into a zip file.
  2. Add Unity layer in ProtoPie: In ProtoPie Connect’s Stage view, click add and select Unity.
  3. Import the WebGL build: Click Insert to import the WebGL build zip file.

For more detailed instructions, check out the documentation on Configuring Unity Layers.

Unity plugin use cases

The Unity plugin enables various use cases across various fields that require interactive prototyping. Below are a few examples:

  1. Game prototyping: Use Unity to develop game mechanics and environments, then bring your Unity project into ProtoPie to test menus, HUDs, and other interface elements.
  2. Automotive interfaces: Prototype advanced automotive interfaces by integrating 3D car models and environments from Unity with interactive UI components in ProtoPie. This can be used for in-car entertainment, navigation, and control interfaces.
  3. Virtual Reality (VR) prototyping: Leverage Unity's VR capabilities to build VR experiences and seamlessly integrate them with ProtoPie for designing and testing user interfaces and interactions.
  4. Healthcare applications: Create prototypes for healthcare applications involving 3D anatomical models or simulations.
