+In the Spline Debug scene, there are 6 important objects:
+
+1. Spline
+- A curved spline going from (0, 0, 0) to (10, 0, -5)
+
+2. Deform
+- A curved spline used to deform Spline
+
+3. Spline Plus
+- An object with the SplinePlus component
+- This object is used to deform spline Spline along spline Deform
+- The resulting spline is rendered in green with Gizmos enabled
+
+4. Evaluate
+- Renders a cube gizmo along each of the above splines at a given distance from a given anchor point
+
+5. Nearest Point
+- Renders a cube gizmo at the nearest point along the deformed spline from the Spline Plus object
+
+6. Spline Debug
+- An instantiated Blender file including a tube warped around the deformed spline using Blender's Curve modifier
