Unity Reflect FAQ

General questions

Do I need the Unity Editor to use Unity Reflect?

You do not need the Unity Editor to use Unity Reflect. Unity Reflect is a standalone product. However, if you are a developer, you can build on top of Unity Reflect with the Unity Editor to create the best experience for your users. Our installer includes a reference application and documentation to make it easy to develop and customize your own applications.

Which releases of the Unity Editor are compatible with Unity Reflect?

Unity Reflect supports all 2019 releases of Unity and will always support the latest release of Unity.

Which Unity plans offer Unity Reflect?

If you wish to use the Unity Editor with Unity Reflect, you can only do so with Unity Pro. Unity Reflect is not available with Unity Plus or Unity Personal.

Are there fees associated with building and commercially distributing a custom Unity Reflect application?

Yes, please speak with a sales representative to learn more.

Which versions of Revit does Unity Reflect support?

It supports the 2018, 2019, 2020, and 2021 releases of Revit.

Which versions of Navisworks does Unity Reflect support?

It supports the 2019, 2020, and 2021 releases of Navisworks.

Which versions of SketchUp does Unity Reflect support?

It supports the 2019 and 2020 releases of SketchUp.

Which versions of Rhino does Unity Reflect support?

It supports version 6 of Rhino.

Is Unity Reflect a cloud-based product?

You can use Unity Reflect on-premise or through cloud hosting.

Is Unity Reflect an open source product?

No. We give subscribers access to our Viewer’s source code, but you cannot contribute to this code.

Who needs a license for Unity Reflect?

You need a Unity Reflect license for every user who uses the Unity Reflect plugins as well as for every user who will be developing Unity Reflect-based applications. Not every user in your organization will necessarily need a license.

You do not need a Unity Reflect license to access the Viewers; however, Viewer users need to create a Unity ID to access the projects.

Are floating licenses available?

Not yet. Floating licenses will be available in 2020.

How do I bring Reflect projects into the Unity Editor?

You can import packages within the Unity Editor. To install the Unity Reflect package in the Editor, you will need to enable "Show Preview Packages" under the advanced options in the Package Manager. When you import, Unity Reflect simply creates a prefab.

What’s on the roadmap for Unity Reflect?

Visit our public roadmap here. We’d love to hear your feedback.

Data preparation and optimization

Are there limitations on the size of models I can bring into Unity Reflect?

Performance varies depending on the size and complexity of the model, the publishing platform (Revit) and the viewing platform (PC, iOS, AR, VR). A best practice is to test out a few scenes; if a model is too large and hampers performance, you can use section boxes.

Is there a limit to the number of users who can sync projects to Unity Reflect?

No. The only requirement is that all users have a license of Unity Reflect.

Does Unity Reflect support file-based formats (IFC, FBX, DWG, DXF)?

Unity Reflect does not support file formats. We support direct, memory-to-memory connections between Unity Reflect and digital content creation applications like Revit.

Does Unity Reflect use PiXYZ?

Unity Reflect does not use PiXYZ as part of its data federation process. The aim of Unity Reflect is to facilitate design review across multiple designers and engineers, allowing users to sync in real- time across multiple iterations. Unity Reflect does not include any decimation, hole filling, hidden geometry removal or other geometry optimizations that are possible with PiXYZ. PiXYZ also provides a very powerful rules engine that can help you build the best runtime possible. Both products deliver real-time 3D optimizations, but for very different use cases, users and goals.

What is the locally hosted server included with a Unity Reflect license?

It's where the data is held and processed. The server can be your local machine (i.e., PC) or a central server. It is not cloud-based at this time.

Does Unity Reflect perform any data preparation or optimization?

Unity Reflect performs two types of transformations:

  1. Object merging to reduce the number of objects in the scene (stairs, ramps, windows, etc.)
  2. Material mapping for compatibility

It does not perform any decimation or tessellation of geometry. We expect to add additional decimation and optimization steps in 2020.

Does a Revit user need to be connected to the local network to sync files?

Yes. If a user is not connected, their portion of the model will not sync. Their modifications will be accumulated until they connect to the network, at which time they will be automatically synced. The only exception is when Revit and the Viewer are running on the same computer.

Where is data stored in Unity Reflect?

Every computer that runs Unity Reflect can act as a server. Each server runs locally on the machine and has it own data storage, which stores the models federated from Revit.

When you begin syncing models from Revit to Unity Reflect, you can push this data to the server of your choice (or even multiple servers across different computers). By default, all servers are private, but you can give access to other users in the privacy settings of a server and manage access right from your Unity project page.

While everything is stored, the data is ephemeral. This means that you will not lose anything if you delete the files or make a mistake (e.g., pushing the wrong data to a project). You can always regenerate the data from Revit.

This server storage is independent of the Viewers, which have a data cache that allows users to view data offline.

What unit system does Unity Reflect use? Is it adjustable?

Unity Reflect uses meters, and at the moment, you cannot change this unit of measurement in Unity or Unity Reflect. If you import a project that uses a different unit of measurement, the measurements will be converted to meters automatically.

Does the live link work with local files or central files in Revit?

Unity Reflect uses local files, and a user can modify only the data that they contribute. Multiple users can make changes to their respective models at the same time.

Can I manage user access rights and permissions to projects?

Yes. Every Unity Reflect project will show up in the Unity developer dashboard. From there, an admin can manage access rights and grant or revoke access to projects.

What is the project management server included with a Unity Reflect license?

We use a cloud-hosted server to indicate the location of the various servers you are using to store Reflect projects. No 3D data is stored in this server, just the names and locations of the projects.


Does Unity Reflect support a web-based Viewer?

You can use Reflect to import data, which can be used in a WebGL application, but cannot build a WebGL viewer.

Is Unity Reflect only available at run time?

No. You can open a live link to a Unity Reflect project with Unity and view the project in the Editor.

Can people in different offices transfer Revit models to the same Unity Reflect project?

Yes, provided they are on the same local network.

Can people in different offices access the same project in the Viewer?

Yes, provided they are on the same local network.

How many concurrent Viewers can be connected to Unity Reflect?

As many as you need.

Can I limit what certain users see?

Not at this time. Every user controls what they see by interacting with the Viewer – there is no unified view across Viewers.

Which metadata is transferred to the Viewer?

All BIM metadata is transferred, including support for instance-specific metadata.

Can I roundtrip between Unity Reflect and Revit?

Unity Reflect is unidirectional. Changes made in Revit can be synced to Unity Reflect, but not vice versa.

Can I view my models offline?

Yes. Models can be cached in the application on Windows or iOS and viewed offline after syncing.

Does Unity Reflect support virtual reality (VR)?

Yes. It supports the HTC Vive. Support will expand to additional platforms in 2020. But note that once you bring a project into the Editor, you can deploy it to Oculus and other VR platforms.

Does Unity Reflect support augmented reality (AR) capabilities?

It supports tabletop AR on iOS devices. This feature relies on ARKit’s plane detection, and, as such, the model may drift as you move away from its initial location.

Can I brand the Unity Reflect Viewer?

Yes. The standalone Viewer is Unity branded, but we also provide the Viewer reference application source code. This lets you customize the Viewer in the Unity Editor to feature logos, custom user interfaces (UIs), and more.

Can I take pictures or videos of the model within the Unity Reflect Viewer?

Not at the moment.

What level of rendering realism can be achieved using Unity Reflect?

Unity Reflect currently supports the default render pipeline. By bringing your Reflect projects into the Editor, you can create environments with high visual fidelity. We plan to extend support for the Universal Render Pipeline (URP) and High Definition Render Pipeline (HDRP) in 2020.

Known Issues and limitations

What are the limitations and known issues of Unity Reflect?

Here are a few things to be aware of:

  • You must be on the same network to be able to download projects. If you are not, the download won't start and you won't get an error message. Reflect projects from previous versions are incompatible.
  • The plugins don't have a progress bar for export progress yet. We rely on Revit's built-in progress bar for now.
  • Unity Reflect materials are only compatible with the Standard Rendering Pipeline. If you want to use URP or HDRP, you will need to replace all materials.
  • Changing a Clipping plane in Revit won't update the model in Reflect. The model needs to be re-exported.
  • The Reflect Viewer does not automatically launch after exporting a project.

We are working diligently to resolve these issues and limitations in subsequent releases of Unity Reflect.
