I’ve been recently having a problem with animating spline meshes, my goal is to create a animated scene of a Lift Operation / Sequence for a piece of a equipment know as a “BOP”, in this sequence there are 2 wires, a winch wire and a sort of “zipline” wire that the equipment travels along.
During this sequence the zipline will slack down to pivot the equipment into place, I’ve create a custom spline mesh blueprint as normal spline points cant be accessed by the sequencer making animating rope, wire or chains difficult, I achieved this by creating spline points attached to an array of vectors that’s exposed to the sequencer and setting up a repeater event to update the mesh during the animation.
In the sequencer / viewport this works perfectly and animates exactly how I want it too however when I go to render, the movement of the spline mesh creates a phantom at its previous location for all previous locations which creates a “MS windows crashed window drag effect”.
Is there any know way to fix this or create a better way of animating Wire rope that can flex / bend and coil / slack that wont create this effect?
