Previewing Effects in OpenGL Mode
If you want to playback your animation and see rendered effects, you can use the Preview node to see your effects in the Camera view OpenGL mode.
- To adjust the effect's visual controls in OpenGL mode, from the Node Library view, drag a Render Preview node to the Node view. Connect it between the effect and the Composite nodes.
- In the Camera view, enable the OpenGL mode to see the rendered effect in OpenGL.
As you modify the effect's parameters and controls, the frames are rendered to ensure a real-time playback. The larger the resolution and the heavier the effect, the longer the rendering process will take. Green frames are rendered, red frames are pending and yellow frames are rendering.
- To display the controls, select the node in the Node view, and do one of the following:
|‣||In the Camera View toolbar, click the Show Controlbutton.|
|‣||From the top menu, select View > Show > Control.|
|‣||Press Shift + F11 (Windows/Linux) or ⌘ + F11 (Mac OS X).|
The controls appear.
- In the Tools toolbar, select the Transform tool or press Shift + T.
- In the Camera view, adjust the controls.
- To set the preview parameters, click the yellow square properties button on the Preview Render node.
The Preview Render properties display.
