These are sets of animated arrows for the purpose of visualising motion.
All sets do a 90 degree turn, with different radii in 3 different versions: A version laying flat, a version standing up and a version spinning, seperated into 3 files
One arrow has the size of 120 cm (about 4 feet), but it's easily scalable to you needs.Every arrrow set consists of 5 arrows and has a a unique parent helper.Merge it into the scene with all childs, move, rotate, scale the helper until it fits.The animation is done via pointcache and animated visibility track, so you should be able to simply adjust it as well.
Furthermore the setup objects for the pointcaches are included, so you can do your own styles.Everything is named properly and sorted to logic layers.It might be possible that you have to reassign the pointcache files in the assest manager on you system. To get it work on a render farm paths need to be absolut.
In the max files, only one pointcache is used per arrow set, but each arrow uses an own playback graph to run it.In the FBX files, a unique poincache of 2000 frames for each arrow was created. arrows are not subdivided here.
