Draw Debug Coordinate System
| Inputs | |
|---|---|
| Axis Loc | Position in World Space of indicator's origin. |
| Axis Rot | Rotation in World Space the indicator will orient. |
| Scale | Length of the drawn axis lines. |
| Duration | Length of time to render each drawing. Zero will last until the end of the frame. |
| Thickness | Thickness of the drawn axis lines. |
| Inputs | |
|---|---|
| InWorld | Reference to the current world to draw in. |
| AxisLoc | Position in World Space of the indicator's origin. |
| AxisRot | Rotation in World Space the indicator will orient. |
| Scale | Length of the drawn axis lines. |
| bPersistentLines | Persist drawn lines permanently. |
| LifeTime | Length of time to render each drawing. |
| DepthPriority | Scene Depth Priority Group that the indicator will rendered be in. |
| Thickness | Thickness of the drawn axis lines. |

Overview
Draw Debug Coordinate System will render a visual-only transform gizmo at the selected position and rotation. Its size, duration, and line thickness can be controlled.
A helpful visualization tool for debugging, this can render an indicator at any position and rotation.
Depending on the connected inputs, this can render oriented as world or local space.
The Duration input will dictate the frequency of node executions. If set to zero, you will need it to execute each frame, otherwise, pulsing it will draw it once and keep it there until it elapses.
Detaching from the controlled actor will allow the selection of a scene object; This will show the standard Transform gizmo if only a quick check is needed.
Scale & Thickness
Here is a quick reference of typical values for the Scale and Thickness inputs. Values can be updated at run-time with variables if needed.
These are shown on a standard-size Cube Mesh (100 x 100 x 100).
Examples
Object Position & Rotation
Draws an indicator on every frame at the object's origin that aligns with its rotation.
