<p>
This page lists all parameters of the Enterprise PBR Shading Model and its subtypes.
</p>
<p>
Each parameter is of a certain type, and has a default, minimum and maximum value. We recommend
that a UI displays the parameters in the order given in the following table, grouped
by the string in the "Group" property.
</p>
<p>
Subtypes provide defaults for certain classes of materials, like metal, textile, or glass.
Subtypes significantly reduce the amount of parameters presented to the user. The "Hidden"
property of a parameter indicates that a parameter must not be visible in the UI.
