Snapshot | This node makes a snapshot of the current render output and provides it as a texture. |
When triggering the Shutter method, the Snapshot node will make a copy of the current render output and store it inside itself. The copy is provided as the Texture output property and will stay the same until the Shutter method is triggered again.
The Succeeded event is fired in the next frame cycle but before any other graphics are rendered. Binding the Succeeded event to the Save method of a Texture Saver node will therefore save the texture "right after the shutter was invoked" although technically the saving is done in the next frame.
The image inside the Snapshot node will not be stored when the scene is saved.
