Scaling 'sweep' spline sub-object.
As part of the Tyre-Tire script I wanted to include an option which would scale the 'Sweep Modifier' custom shape in proportion to changing the radius of the created object.
Whilst a simple 'scale' on the whole object would have done the job perfectly well I was intrigued to see if I could replicate the really easy 'manual' method with some mxs code.
The end result was to add a Linked XForm modifier to the spline object and apply the scale to 'it'......thus scaling the spline sub-object and also updating the 'sweep' modifier.....in real-time.
I have since been reliably informed that this can also be achieved without using the Linked XForm modifier for a more elegant solution.....cue barigazy!
So although a solution is found I very much look forward to seeing the alternative.
