The Predict menu offers an access to all the main Predict Unity functionalities :
Material Editor : opens the Predict Matter material edition window, see the Materials section for more details,
Prepare Materials for Build : when building an application using Predict Engine for Unity, some elements in the scenes (the materials especially) require a specific preprocess, this menu calls all required preprocesses, see the Deployment section for more details,
The Matter Settings section offers some generic options for all the materials, lights and spectrums in your project :
The Materials/Double Sided option defines whether materials should be applied on both sides of a surface or only on the face pointed by the normal : see the Geometries section for more details,
The Area Lights/Emit on both sides option defines whether area lights emit from both sides of the geometry or only in the direction defined by the Unity light,
The Area Lights/Default Material option defines which material is used on area lights defined without a "Mesh Renderer" component,
The Spectrums/Preview Illuminant option defines which illuminant is used for the preview color of materials' spectrums : see the Spectrums section for more details on spectrums.
