|
file |
file |
N/A |
Sets the file path to write vectors out to disk for use with VectorDistort. NOTE: SmartVector can only write .exr files to disk. If you specify another file format, an error displays in the Viewer. |
|
range |
render_range |
input |
Sets the range of frames processed by SmartVector: • input - the default value, sets the frame range to the length of the sequence attached to the Src input. • global - sets the tracking frame range to the range set in the Project Settings > frame range controls. If no frame range is defined, the frame range of the first image you read in is used as the global frame range. • custom - sets a range of frames described by the from and to fields. |
|
from |
file.first_frame |
1 |
When range is set to custom, this control sets the first frame to process in the sequence. |
|
to |
file.last_frame |
100 |
When range is set to custom, this control sets the last frame to process in the sequence. |
|
vector detail |
vectorDetailReg |
0.3 |
Sets the vector quality. The default value of 0.3 is sufficient for sequences with low detail and movement, but you may want to increase the detail to improve the vector quality in some cases. NOTE: High detail vectors take longer to render, but can improve the results you get from the VectorDistort node. |
|
Render |
render |
N/A |
Click to render the frame range specified to the file path entered in the file control. |
|
Python Tab (These controls are for Python callbacks and can be used to have Python functions automatically called when various events happen in Nuke.) |

|
before render |
beforeRender |
none |
These functions run prior to starting rendering in execute(). If they throw an exception, the render aborts. |
|
before each frame |
beforeFrameRender |
none |
These functions run prior to starting rendering of each individual frame. If they throw an exception, the render aborts. |
|
after each frame |
afterFrameRender |
none |
These functions run after each frame is finished rendering. They are not called if the render aborts. If they throw an exception, the render aborts. |
|
after render |
afterRender |
none |
These functions run after rendering of all frames is finished. If they throw an error, the render aborts. |
|
render progress |
renderProgress |
none |
These functions run during rendering to determine progress or failure. |
