Hi anyone know of a formula to convert a driven bones distance into the correct value for the generator in the drivers panel I’m still just doing trial and error it would be nice to know a efficient way of getting the correct value.
If I understand things right, you want to convert Z values in the range (-5, 5) to be used as influence in the range (0, 1). So…
Influence = (Z + 5) * 0.1
+5 to move into the range (0, 10) and * 0.1 to divide by 10 and fall back into the range (0, 1). Simple…
A formula to write on a Post-It:
To convert a value A in range (minA, maxA) into B in range (minB, maxB)
offset = minB - minA
scale = (maxB - minB) / (maxA - minA)
B = (A + offset) * scale
With your values:
minA = -5, maxA = 5
minB = 0, maxB = 1
offset = 0 - (-5) = +5
scale = (1 - 0) / (5 - (-5)) = 1/10 = 0.1
B = (A + 5) * 0.1
Correct! 
Hi Kaluura
Thanks very much for the reply and formula I will definatley give it a go 
I had another go at trying to figure out and understand what was going on and managed to come up with a solution, it took me all day to work out so would be a shame not to post it. Probably not the easiest way but was rapt to end up with a result.
