changing motionpath values via attribute or expression?

[Anonymous]

I have a cv curve with locators attached via motionPath - animation node has been removed so moving the timeline doesn't affect them

locator a @ 0.0 u value
locator b @ 0.1 u value
locator c @ 0.2 u value

I want to move all of the locators at once, based on another keyable attribute in something like a global controller - this attribute would be called "locatorPositions"

as you adjust the "locatorPositions" attribute, it should add it's value to the locators U values

so if "locatorPositions" was set to .5, locator a would be .5, locator b would be .6, and locator c would be .7 % along the curve

is this possible?

thanks

Hi,

 it is simple task. I have made sample scene with native Maya utility nodes. Check the nurbs curve in the scene. It has custom attribute locator_Position you can change. It is connected via addDoubleLinear node to uValue of each motion path.
