Best Practices

• Use InstancedMesh for rendering many objects with identical geometry and material but different transformations — reduces draw calls dramatically for performance-critical scenes source

• Set needsUpdate = true on instanceMatrix after calling setMatrixAt() and on instanceColor after setColorAt() to notify the engine of transformation changes source

• Always call dispose() on InstancedMesh, BatchedMesh, and EffectComposer when no longer used to free GPU resources and prevent memory leaks source

• Use BatchedMesh for rendering large numbers of objects with the same material but different geometries — provides multi-draw batch rendering to reduce draw calls source

• Reserve buffer space when adding geometries to BatchedMesh if planning to replace with larger geometries later via the reservedVertexCount and reservedIndexCount parameters source

• Set needsUpdate = true on materials after modifying properties to trigger shader recompilation and reflect changes in the next render source

• Disable depth writing for 2D overlays by setting depthWrite = false to layer elements without z-index artifacts source

• Use depthTexture instead of depthBuffer on render targets for post-processing to access depth data in shaders source

• Enable MSAA on render targets by setting samples to a value > 0 (typically 4 or 8) for smoother output, but balance against performance cost source

• Disable generateMipmaps and set it to false if creating mipmaps manually to avoid redundant automatic generation source

• Dispose and recreate textures to change dimensions, format, or type — modifying these properties directly after first use has no effect source

• Set global = true on nodes that should be declared only once (e.g., AttributeNode) in shader graph systems to leverage the internal caching system source

• Update AnimationMixer with delta time in the render loop via mixer.update(deltaTime) to advance animations smoothly source

• Call AnimationMixer.uncacheAction(), uncacheClip(), or uncacheRoot() to deallocate memory resources, but ensure related actions are stopped first source
