Selects (masks) the values interval at a specified level. In simple terms if the value is within From-To range it becomes 1, otherwise it becomes 0 (if not taking transition into account).
Transition effect allows gradual masking - it creates smooth gradients both at From and To ends.
Properties:
-
Set Range: switches the node interface between transition and min/max values. It's the matter of personal preference which UI type to choose (however in Min/Max you can set different transitions for from or to ends).
In Min/Max mode from and to minimal value is converted using X-Transition/2, and maximal: Y+Transition/2
-
Units: determines whether the the map units (ranging from 0 to 1) or world units (ranging from 0 to 250 or whatever set in output/MM object settings. See Height Output for details).
-
From: determines the lower selection range. All values higher this value (or min-max range) will be selected, up to To value.
![From]()
From (while To 0.66): 0, 0.5, 0.55, 0.6 -
To: determines the upper selection range. All values below this value starting with From will be selected.
![To]()
To (while From 0.5): 0.5, 0.6, 0.7, 0.8, 0.9 -
Transition: sets the gradient on Front and To ends for smooth masking:
![Transition]()
Transition: 0, 0.05, 0.1, 0.2, 1
