This node sets the minimum and maximum values of a mask.
To add a Min & max values node, right-click in the Graph Editor and select Create Node > Mask Transformation > Min & max values.
Double click on the node to open its parameters:
Two modes exist to set the minimum and maximum values: Click on either the Maximum value or Minimum value radio button to select a mode and edit the output mask.
The advantage of this mode is that you can change all the minimum and maximum values of your mask without going back through the previous nodes.
Values lower than the minimum value are raised to the minimum value. Values higher than the maximum value are lowered to the maximum value.
|Maximum value||The maximum value of the output mask|
|Minimum value||The minimum value of the output mask|
|Scale||The values of all the vertices are scaled over the entire mask according to the new minimum and maximum values|
|Clamp||The vertices are constrained to a minimum and maximum value; vertices with a value lower than the minimum value are raised to the minimum value and the vertices with a value higher than the maximum value are lowered to the maximum value|
