<h3>Details</h3>
|
||
|
|
<p>This node will linearly scale the received value. By default, the result
|
||
|
|
is not constrained to the range defined in the node.</p>
|
||
|
|
<p><i>Scale and limit to target range</i> means that the result will never be outside
|
||
|
|
the range specified within the result range.</p>
|
||
|
|
<p><i>Scale and wrap within the target range</i> means that the result will
|
||
|
|
be wrapped within the result range.</p>
