Hi,
I want to drive a bone X rotation with a value based on two other bones Z position
TargetBone.rotation.x = BoneA.location.Z - BoneB.location.Z
but I dont understand how to do that with dirvers
it is asking for a path, but how do I find the path ?
do I have to use a property ? then how do I update that property from that delta Z ?
thanks for your help
The easiest way to find a path, for me, is to right click in a particular field and copy as new driver, then paste as new driver somewhere else. Once you have a field, you can copy/paste that entire variable with the copy/paste buttons in the driver editor, or you can just select and copy the data path text.
There’s also “copy data field” operation, but there are problems involved with it.
In var_001 click the DNA like icon next to the name, and change it to the one that like this : (x)
Then you’ll have the same settings as the first variable ( var)
then the expression could be something like : abs(var - var_001)
Or you can retrieve the path as bandages suggests ,
using path is a more universal way of accessing any data, but as you’re dealing only with location,
the (x) icon type is enough.
I just figured out that in the menu there is a “Distance” variable type worth looking into for your case. An now you’ve got 3 different ways of doing what you want, isn’t that wonderful ?
Good luck !
ok I found out I had to use transform channel
whish these “drivers” feature was more documented with examples and stuff
