Parameters
| Name | Description |
|---|---|
| InPixelPos | The desired position within the view in pixels. |
| InSceneView | The view that was displayed when the pixel position was chosen. |
| InOriginOffset | An offset to apply to the origin before calling TraceScreenRay (if this is in orthographic mode). |
| OutOrigin | The origin point of the view. |
| OutDirection | The direction relative to the origin. |
