Description

Create a line on screen which traces the path af an animated object. It’s Substitute for tracing arcs on your screen by hand with a marker. It can be used either as an overlay on your camera view, or in world space. It’s a bake process; like a marker it doesn’t update interactively. Lines are colored to distinguish between multiple traces. Frames are marked along the arc as black dots, with keyframes colored red, and the current frame is highlighted.
