Reply To: When to clamp the Mapping Node?
Spikey’s explanation is spot on!
Here I have created a visual example.
A plane with a simple Displacement, the scale of the displacement is controlled by the map range node with the input value from the value node with a driver giving the frame number as the value.
The From Min and Max are the frames 1 to 50, and the To Min and Max are the displacement scale from 0 to 1.
As you see with the map range clamped, at frame 50 the scale is clamped to the To Max value of 1.
When unclamped the displacement scale continues, in this case with 100 frames, in linear value to 2.
I think the naming on the map range node is a little confusing! 😕
It would be better if the From Min and Max was named Input (or in) Min and Max
and the To Min and Max was named Output (or Out) Min and Max
