I'm having difficulty trying to successfully set up a flow path object. In a nutshell, I have a simple piece of geometry (an arrow) that I need to have flow along a motion path (nurbs curve). I'm using the "attach to motion path" workflow to get the geometry to follow the motion path. Then I use "flow path object" to get the geometry to actual flow along the curve. So far so good. The problem is that I'm getting twists in my ffdLatticeShape which is causing my geometry to twist and pinch at certain areas of the motion path. I've increased the S divisions on the lattice but I'm perplexed on how to untwist the bad sections of the lattice so that the geometry flows smoooothly. Please help.
