Predict Engine works with a set of input assets : geometry files, measured materials, measured environments, light intensity profiles,... 

We provide some default assets with the Unity package : after installing the Predict Suite package in Unity, a pop up window will let you download and install these assets. You can also find and download the default assets and others from the Predict Suite menu : see the Default Assets section for more details.

We also provide some demo scenes : the UVR shader ball scene is always included in the Unity package, and some more complex scenes can be downloaded from the Predict Suite menu : see the Demo Scenes section for more details.

If you need more resources, you can find some in the following libraries :
