1 · Position. Pick a map. At 1:55 (rewind ⏮) dragging a piece moves its spawn point — that is the round's starting position. Set each player's label and weapon class in the right panel — timings use that class's run speed.
2 · Draw. Select a piece, switch to Path and click the route. Timings come from real CS2 movement speeds (weapon class × fast run/run/walk/crouch). Use G to draw grenade lines: click the vertices — straight throw or wall bounces — and finish with Enter (last point = where it pops).
3 · Edit the nodes. With V, click a waypoint to jump the clock to that moment, then drag it — its time and every node after it recompute on the spot. Click anywhere on the route between two nodes to insert a new one (A→C becomes A→B→C).
4 · Watch. Press play ▶ and scrub the timeline. Smokes bloom and fade with real durations.
