SceneCloner

The SceneTracer class provides an interface for performing Node Clone operations initiated by shaders. To execute a clone operation, the clone_graph_node() or clone_graph_nodes() GLSL function must be used, and the clone action will be completed on the next frame. For low-level control, the CloneParameters structure can be used, where the first element of the clone buffer contains the clone index, transform index, and the maximum number of transforms. The SceneManager class offers a clone callback interface that allows subscriptions to clone events.

info

The SceneCloner is available for GraphVarying shaders.
