Default Assets
We provide a set of default assets. Some are already present in the package and others are downloadable via the menu "PredictSuite/Download/Assets Library" :
You need a valid license to be able to download assets.
Default assets downloaded when first installing the package
Camera spectral response curves
Measured spectral response curves for standard photographic sensors are stored in the assets folder : "Assets/Default Assets/Cameras SRC". These curves should be used on photographic sensor of type "Measured", see the Optical Instruments section for more details.
On the right : default scene previewed using different spectral response curves on a measured photographic sensor.
Sensor : arri_d21_380_780_5
Sensor : canon_eos_5d_mark_ii_380_780_5
Sensor : nikon_d70_380_780_5
Sensor : nikon_d700_380_780_5
Sensor : nikon_d7000_380_780_5
RGB environments
A few RGB environments are stored in the assets folder : "Assets/Default Assets/Environments". These environments were loaded from the HDRI Haven Library. These environments should be used as RGB skyboxes in the scene, see the Environments section for more details.
HDRI : old_depot_2k
HDRI : immenstadter_horn_2k
HDRI : red_hill_curve_2k
IES lights
A few IES lights are stored in the assets folder : "Assets/Default Assets/IES". Some of these files are internal measures and other were loaded from the Derek Jenson Library. These IES should be used on area lights of type "Photometric", see the Light Intensity section for more details.
On the right : photometric area lights using different IES profiles, previewed in a white box.
IES: ParallelBeam
IES: ScatterLight
IES: XArrow
IES: JellyFish
IES: AreaLight
Measured materials
A few measured materials are stored in the assets folder : "Assets/Default Assets/Measured Materials". Some of these files are internal measures and other were loaded from the Refractive Index Library. See the Materials section for more details.
Car paint materials, glasses and water
Leathers with different texture scales
Pure materials defined with indexes of refraction and extinction (metals, plastics), measured metals and plastics
Model materials
A few RGB/model materials are stored in the assets folder : "Assets/Default Assets/Model Materials". These materials are defined by models and can be used for the scenery elements. See the Materials section for more details.
Lambertian materials, shadow catcher, polarizers
Downloadable assets
Unity RGB materials
Unity provides a library of HDRP materials. These materials are measured but they only use RGB data. We distribute this material library for Unity HDRP and for Unity Legacy.
The library contains a set of scratched metals, leathers and fabrics.
Texture Haven RGB materials
Poly Haven is an online library that distributes environments, material textures and geometries. We distribute a part of this library already preset for Unity.
The Texture Haven library we provide contains mostly a set of external materials (floor, paints, plasters, dirt,...), some fabrics and wooden surfaces. More textures are available in the online library.
HDRI Haven RGB environments
Poly Haven is an online library that distributes environments, material textures and geometries. We distribute a part of this library already preset for Unity.
The HDRI Haven library we provide contains indoor and outdoor environments. More environments are available in the online library.
Measured displays
Displays can be measured by our teams. We provide two different measured displays for you to try our measured display functionality.
If you need a custom measurement, feel free to contact us at contact@united-vr.com.

Spectral and polarized environments
Environment maps should contain spectral and polarized data. We provide a set of spectral and polarized skies generated from a model definition.
Our team can measure such environments and we provide a software that generates spectral and polarized environments from a model definition. Feel free to contact us at contact@united-vr.com.
Set of spectral and polarized Predict Sky environments.
The images are saturated in Unity because the values are HDR.
These skies should be referenced on the UVR Skybox Settings component with a "Procedural Sun" definition (see the Environment section for more details).
The corresponding sun should use the following settings:
Apparent Radius : 0.2585 (default size of the sun)
Latitude : 35.685
Longitude : 139.7514
Date : 15/05/2022
Time : depending on the texture (07h00, 11h00, 14h00, 18h20)
Time Zone : 9
Turbidity : 2
Presets of the UVR Skybox Settings component are provided with the textures. You can use them by clicking on the preset button in the Unity component tool bar (see image here against). By selecting one of these presets, the component will be automatically set up, using the right textures and the corresponding sun settings.
