Data Type
Denes the node’s data type.
Input Range, Output Range, Input Lower, Input Upper, Output Lower, Output Upper
Here you can choose commonly-used ranges such as 0% to 100%.
 User Dened: In this mode, the input range and the output range are dened
by the values in the Attribute manager for Input Upper, Input Lower, Output
Upper and Output Lower (or by the ports of the same name, if you have added
these).
 Degree: Denes the range 0 to 360.
 Radians: Denes the range 0 to 6.283. This corresponds to 2*PI.
 Percent: Denes the range 0% to 100%.
 Zero To ...: These modes dene the ranges 0 to 1, 0 to 100 and 0 to 1,000.
Clamp Lower, Clamp Upper
These settings automatically restrict the input value to the input range (i.e. to values from Input Lower
to Input Upper). If the input is outside the range, it is clamped to the Input Lower value or the Input
Upper value — whichever is closer. For example, suppose the input range is 0 to 36 and the output
range is 0 to 100. An input value of 38 would be clamped to 36 (the upper limit of the input range),
leading to a remapped output of 100. A negative input value would be clamped to the lower input
limit — in this case, 0. You can enable the Clamp Lower and Clamp Upper options independently of
each other.
Modulo
If this option is enabled, the input is adjusted dynamically to t the input range. For example, suppose
you’ve enabled the Modulo option, dened an input range from 0 to 100 and disabled Clamp Upper.
An input of 101 will be adjusted to 1 (101 modulo 100 = 1). In other words, the input value will be
divided by the upper limit and the remainder will become the new value. No matter how high you
raise the input value, the Modulo node always cycles within the input range. This is especially useful
for angles rotated past 2*Pi (360°) in the viewport; you can then work with values in the range 0° to
360°.
Reverse
The Reverse option reverses the output range. For example, an input that is the same value as the lower
input limit will be remapped to the value of the upper output limit instead of the lower output limit.
