hi…
what input i should type in the expression field in Drivers dialgbox…
(right now i have typed… ‘var - 5.144’)
when i move the slider in Xaxis, it should gradually , slowly change
from A to B shape. ie 0 to 4. now whats happng is… within 0 to 1 itself,
the shape A to B is getting completed. how to extend A to B to 0 to 4…
plz help…
thank you
Try
(var - 5.114) * .25

hi randy, thank you very much !
the syntax you suggested me nicely worked.
can you pl explain me the syntax esp why we should put values inside bracket…
so that i can understand also !
The parenthesis are there because of the mathematical order of operations.
Basically, we want to do var - 5.114 first - which is giving you a value of 0 to 1+, as is seen when you move the slider. So when you move the slider from 0 to 1, to get the result of 0 to 1. You wanted a result of when you move the slider from 0 to 4, the output should be 0 to 1 (for the shapekey).
So you do (var - 5.114) first, then multiply the result by .25 to give you a result of 0-1 when the slider is moved 0-4. You could also do
(var - 5.114) / 4
Which would give you the same result, but might be easier to understand.
Hope this helps,
Randy
Hi randy… Thank you very much.
If you have time, can you pl tell me abt how to add an inbetween shape key.
either in shape-keys column in data props or in
slider using drivers.
0 = neutral
.5 = ‘a’ (syllable shape)
1 = ‘m’ (syllable shape)
