Hi! I know I’m a little late to this party, but I’ve been trying to use this method for swimming fish and I’m running into the same problem shown in the video here (the squish on loop, which seems like it’s just the back end catching up to the front end?). Judging by this thread it looks like you moved on to other methods, but I was just curious if you had any idea how to fix this. The fish are relatively short meshes that don’t need to perfectly deform along the spline, so this method is well-suited to my needs in almost every other way and it would be fantastic if I could get this working.
