Inverse Lerp

Postby jimmyneutron » Thu Nov 30, 2017 2:46 pm

Hi all,

A node I used often in shader forge was inverse lerp, but it appears there is no such node in amplify. does it exist as another node i am unaware of?

I suppose i could use Smoothstep, but it would be ideal to be able to control the interpolation.
alternatively I guess its also possible to remap and then saturate.
But just asking, incase there is another solution.

regards,
jimmy.

Hello Jimmy!

Although we don't have an InverseLerp node, the equivalent alternative would be to use the Remap Node by setting the Min New and Max New ports to 0 and 1 respectively, and then use Min Old and Max Old in the same way you'd use ports A and B in the InverseLerp node, and finally saturate the generated output like you pointed out.

Please let us know if you have any further questions, thanks!
