Lets say I have an object, and I want to color ramp it based on magnitude rather that say Z height - because Z height would ramp colors exactly at the same height and give a mechanical look to the ramps over several objects.
The object like a tree could have long and short branches, low hanging long ones or tall short ones, in either case the ramp by Z height would not work, it would produce a mechanical coloring across the object. If you could do it by length, you could have a coloring effect from base to branch tip, which looks awesome. I can do it now by magnitude, but if I move my objects the value changes because the origin distance. So I would have to go back to each event every time I move an object to a new position. So I thought it would be awesome if you actually have a "travel distance from birth" to use as a source for custom float. Which in essence is the same value as now, minus the first distance - origin to birth.
