MEL Expression Shows No Errors But Still doesn't Work. Help?


#1

Since last summer I’m trying to rig the treads of a tank model and I go from one problem to the other until I reach a dead end every time.
This time I started following a Pluralsight tutorial in which the instructor uses the expression below on the U value of the attached tread piece that would move along the path once the tank control gets translated. Except it doesn’t work for me and I don’t get any errors to get an idea at least of what’s wrong.

motionPath1.uValue = L_track_CRV1.translateZ/treadsInfo.arcLength;
