Roblox Speeds Up EditableMesh With Batching and Parallel Queries

Creators can replace thousands of per-element calls with bulk operations and distribute expensive raycasts or spatial lookups across Actors. The beta is enabled through File > Beta Features > EditableMesh Batching and requires a Studio restart.

Roblox Speeds Up EditableMesh With Batching and Parallel Queries

All EditableMesh query methods, including RaycastLocal, FindClosestPointOnSurface, FindClosestVertex and Get* accessors, can run after task.desynchronize(). Only reads are parallel-safe: creators must call task.synchronize() before adding, removing or changing mesh data.

The nine APIs cover bulk creation, removal, clearing, value updates and attribute queries. Enum.MeshAttribute selects Vertex, Normal, UV, Color or Face data; IDs of different types cannot be mixed in one call, and skinning is not supported.

Why it matters

The change targets procedural geometry and other mesh-heavy systems where call overhead or serial reads limit frame time. Roblox says results depend on mesh size and access pattern; its figures came from a 2019 phone with 2 GB of RAM, not a universal guarantee.

Nine new batching methods.
Parallel reads; serial writes only.
