public struct UIMesh

UIMesh.vertices and UIMesh.indices are required. The optional extras (UIMesh.uv1, UIMesh.uv2, UIMesh.uv3, UIMesh.normal, UIMesh.tangent) are channels the panel must have opted into via PanelSettings.extraVertexChannels or IPanel.extraVertexChannels. Providing a slice for a channel the panel did not enable logs an error and drops that slice.

Each non-empty extras slice must have ; mismatches are logged and the entire draw is dropped.

Channels enabled on the panel but left empty in the draw are zero-filled.

Slices passed to MeshGenerationContext.DrawMesh are read at flush time, not at the call site. Slices returned by MeshGenerationContext.AllocateTempMesh are guaranteed valid through the flush; user-supplied slices must remain valid until the same flush point.
