Falloff looking at object Tweet

[Rico_uk]

HI all, I've struggled a bit with using the 'direction' in the falloff node, it's quite hard to control so I've made a bit of a workaround and thought I'd post here in case it helps anyone. Max file and video attached.
Essentially changing the controller of the direction parameter in the material to a Point 3 XYZ controller to expose each value. Then using wire parameters to link these values to the local axis positions of an object which is parented to the object that has the falloff material. Worth noting that Y and Z are switched, so the local Y position should affect the 3rd slot in the direction parameter. Another thing to note is the Y axis from Max needs to be inverted. And a final thing is that the values in the direction parameter slot are limited to -1 and 1, so I've divided the local position by 100 so that I get a value small enough, depends on scene scale I suppose.
Would love to have this is a tidy script for linking objects and relative direction, I've tried using a float script which works fine but the problem is that it doesn't update in real time and only updates when I scrub the timeline., so I've done it using Wire Parameters which updates immediately. Any thoughts / additions to make this better would be very welcome!
