Batch rendering highlights in Godot uses MultiMeshInstance3D to manage large numbers of visual elements. This approach updates instance positions and states in batches, keeping high-density unit highlights within profiling budgets.

The best way to handle high-density marker rendering is using Godot's MultiMesh system for batched updates. It optimizes the rendering of numerous highlights by efficiently batching instance data updates for performance-safe visuals.

Yes, MultiMeshInstance3D supports deterministic instance data updates. It manages stable and predictable instance indexing policies, ensuring tactical board visual feedback remains stable during large-scale highlight updates.

Rendering many individual markers causes performance bottlenecks because each visual element requires separate draw calls. Using Godot's MultiMesh batching system solves this by grouping highlights into a single MultiMeshInstance3D.

You should not use MultiMesh batching when tactical board highlights require unique, complex materials per instance or non-batched individual processing. MultiMesh optimization targets scalable visual feedback with uniform batching policies.
