Defining Material Properties as Expressions
When defining or modifying a material's properties, each material property value in the View/Edit Material window can be assigned a mathematical expression by typing the expression in the appropriate Value box. Expressions typically contain intrinsic functions, such as sin(x), and arithmetic operators, such as +, -, *, and /, but do not include project variables.
Note: By default, not
all of the available properties are displayed in the materials table.
Only the properties commonly used by the product are displayed. To view
