CameraCapture represents an image rendered by a
Camera to be used elsewhere in the game, for example in UI. Each camera capture instance uses a certain amount of the memory based on the resolution size. Creators are free to create whatever combination (mixed resolutions) of camera captures needed up until the budget is fully consumed. Creators may wish to explicitly release existing capture instances when they are no longer needed, so that they can create more elsewhere. A released capture is no longer valid, and should not be used thereafter.
The total budget is 8 megapixels (8,388,608 pixels).
Below lists the total number of captures that can be done per resolution. Creators can mix the resolution size as long as the total budget is not above the limit of 8 megapixels.
- 2048 maximum captures at
- 512 maximum captures at
- 128 maximum captures at

||Releases the texture resources associated with this capture instance. This instance will become invalid and should no longer be used.||None|
This example uses the Camera's
Refresh() to implement a rear-view mirror that appears when the player is using a vehicle. For the UI image to look correct, it should have equal width and height, as well as
Flip Horizontal enabled.

This client script demonstrates how several in-game cameras can be displayed onto the 2D UI, one at a time, perhaps in a game with some kind of surveillance system. When a camera is selected to be displayed call the
Capture() function, passing the camera as parameter.
