Vasileios,
About scaling TS meshes. TurboSplines uses 3dsMax’s Path Deform modifier, so every mesh deformation along a spline and its position is tied to the spline.
If you want to scale a TS mesh, you must always scale it together with its corresponding path, to preserve its integrity.
About the second matter, to handle the particular situation in wich you need the hemispherical ends of the capsules to be outside the ends of the paths, I wrote a little script for you. (Attached to this post)
Select the TS meshes and run the script. It will perform the animation positioning the capsules the way you need along the paths.
I hope that helps. 🙂
Best,
Hernan R.
