Download the JanusVR Unity exporter

You can get the exporter by 1 of 2 ways:

Github Source

The JanusVR Unity Exporter is in constant development in the JanusVR Utils Github page: https://github.com/JamesMcCrae/janusvr_utils

You can find the exporter project source code in the folder "unity/Project/JanusExporter", or here

Importing The JanusVR Exporter from Git

1. Install git if you haven't

2. git clone https://github.com/JamesMcCrae/janusvr_utils

3. Copy the folder "unity/Project/JanusExporter/Assets/JanusExporter" to your project

Unity Package

Download the latest release of the JanusVR Exporter by going to the JanusVR Utils GitHub Releases page

Look for releases with the tag unity-*

Importing The JanusVR Exporter

1. Import the JanusVR Package by going on "Assets/Import Package/Custom Package"

2. Select the package you downloaded

If you already had the JanusExporter installed, make sure to completely delete the JanusExporter folder in your project before importing the latest version.

3. Open the exporter by hitting Window -> Janus VR Exporter

4. Dock the JanusVR Exporter window somewhere in your working area

Before Exporting

Optimize your export

Lightmap Settings
- Baked Global Illumination: Checked
- Lighting Mode: Subtractive (Unity 5.6+)
- Lightmapper: Enlighten (Unity 5.6+)

Lightmap Optimization
- Realtime Global Illumination: Unchecked (faster lightmap build times as we cant export realtime lightmaps)

Export Quirks
- If an object uses a texture's alpha channel for transparency, that texture export will be forced to PNG (as JPEG doesn't support alpha).

Exporter Window

Exporter Window Parameters

Asset Objects	Description
Search Type	The algorithm to use to extract the model files.
Uniform Scale	A uniform scale to preprocess models.

Main	Description
Export Path	The folder were exporting the scene to
Use Euler Rotations	If we should export the HTML using Euler rotation instead of using vector directions (only supported on Janus 59+)

Texture	Description
Force ReExport	If we should force exporting all textures to the designated texture format.
Exported Textures Format	If force reexport is checked or the texture needs conversion it will be exported using the specified format.
Exported Textures Quality	If the unsupported format is a lossy format, choose the quality here

Scene	Description
Export Inactive Objects	If we should export inactive game objects
Export Dynamic Objects	If we should export objects that are set as dynamic (i.e. not static)
Export Textures	If we should export textures
Export Materials	If the exporter should output the materials (if disabled, lightmaps are still exported, so you can take a look at only lightmap data with a gray tone)
Export Skybox	Exports the scene's skybox
Skybox Render Resolution	If your skybox is rendered procedurally, we'll have to back it. Each face will have the resolution specified in this box.

Probes	Description
Export Environment Probe	If we should export the environment reflection probe
Probe Radiance Resolution	The resolution to render the reflection probe radiance cubemap
Probe Irradiance Resolution	The resolution to render the reflection probe irradiace cubemap

Lightmaps	Description
Lightmap Type	The type of lightmap to include in the export (see Documentation>Lightmap Options)
Lightmap Format	The texture format to save the lightmaps in
Max Lightmap Resolution	The maximum resolution to downscale the lightmap atlases to (used only on BakedMaterial exports for reference material sizes)
Relative F-Stops	If you're exporting to a LDR texture format, the amount of f-stops we should modify the source image for.

Exporter Window Actions

Export HTML only

This button is intended for when you have already exported the entire scene, but made a change that doesnt impact the already exported models/textures (like changing the position of an object in the scene).

Reset Parameters

Resets all parameters to their default values.

Full Export

Exports the entire scene - models, textures and the html file - to the output directory.

Documentation

Exporter Options

Search Type

Option	Description
Each Mesh	Each mesh on scene will be exported as a single fbx mesh
Per Material	Each material will make single fbx file
Per Lightmap ID (Experimental)	Experimental, groups all objects and exports them by lightmap ID

Lightmap Options

Option	Description
None	No lightmaps are exported.
Packed	Packed into multiple atlases. The optimal option to get the lightmap data inside JanusVR.
Unpacked	Unpacks the atlases into smaller textures, so no objects share the same lightmap texture. Consumes more memory with no gain. (Exists only for compatibility/debugging purposes)
Baked	Bakes the lightmap into the object material. Consumes too much memory while making the main material look poor. (Exists only for compatibility/debugging purposes)

Lightmap Texture Type

Option	Description
PNG	Loss compression.
JPEG	Lossy compression, but way smaller filesize.
EXR	Only supported on the JanusVR native client right now. The only way to get high dynamic range into JanusVR.

Custom Components

Bring Additional Data to Janus

Room Entry Portal

GameObject -> JanusVR -> Room Entry Portal

Makes an entry portal on your Unity scene. You can position the portal and move it around, and this is going to be the entrance to your JanusVR room.

Link

GameObject -> JanusVR -> Link

Makes a link portal on your Unity scene. You can set up the URL, title and all other options, and this is going to be exported as a Link portal to JanusVR.
