Mathematical Expressions in Numerical Inputs

In any VRED function that allows numerical input, you can use a mathematical expression in addition to numeric values.

Valid operators are: +, -, *, /, and ( ).
Relative operators, that change the current value, are: +=, -=, *=, and /=.

Here is an example of using valid and relative operators: To divide a current value of 10 by 2, enter as 10/2 or /=2. The equal sign represents the current value.

Here is an example for multi-selection. Using an expression, such as +=100, adds 100 to the values of all selected nodes.

As for 2024, invalid operators and expressions cannot be entered into input fields.

Note:

In versions before 2024, if the expression is not valid, the input field has a yellow border. Once a valid expression is entered, the input field has the normal orange border when the mouse is hovered over it.
