SurfaceObserver.RequestMeshAsync

Parameters

Returns

bool Returns false if the request has failed, typically due to specifying a bad surface ID.

Description

Call RequestMeshAsync to start the process of baking mesh data for the specified surface. This data may take several frames to create. Baked data will be delivered through the specified SurfaceDataReadyDelegate. This method will throw ArgumentNullExcpetion and ArgumentException if parameters specified in the dataRequest are invalid.

If you expect to draw the resulting Meshes returned by RequestMeshAsync it is recommended that you disable shadow casting and receive shadows on the MeshRenderer for performance.
