Voxel Destruction 2 — Object Cache & Debris

Why Object Cache Matters

Every voxel break can spawn new BasePart instances. Without reuse, Roblox spends time allocating, parenting, and replicating fresh parts — the main source of destruction lag. Object cache (or object pooling) pre-instantiates a pool of parts and recycles them after debris expires.

Community modules migrated toward this model in early 2026: VoxelDestruct 2.1 moved from part cache to object cache; Shatterbox Release 8 (February 3, 2026) added optional ObjectCache integration; Vex 2.0 markets object pooling as a headline feature. VD2's engine targets the same philosophy even though players never touch Studio scripts.

Smooth Cleanup Algorithms

Naive engines delete all debris at once when limits hit — causing visible pop-in. Shatterbox's optional smooth cleanup dynamically removes old operations while preserving active destruction, spreading the CPU cost across frames.

VD2 players benefit when the subdivision queue and debris lifetime cooperate: pausing between heavy tool waves lets cleanup catch up. If rubble freezes mid-air then vanishes, the session likely hit a cleanup threshold.

• Greedy Meshing — reduces parts before cache pressure
• Protect Performance — player pacing habits
• Fix Lag — when cache cannot save your hardware

Weld-Based Falling Debris

Shatterbox Release 8 introduced optional dynamic welding so disconnected fragments fall as coherent chunks instead of floating voxel clouds. Early access feedback to whatever_dev() repeatedly requests similar weld-based drops in VD2.

Weld debris feels more Teardown-like: walls peel, floors pancake, and secondary impacts trigger chain collapses. Until VD2 ships full weld polish, expect some early access maps to leave hovering shards after massive hits.

Client-Server Replication Context

Shatterbox's client-server algorithm copies the map locally before the server authorizes breaks, cutting network replication of every fragment. VD2 runs as a consumer sandbox rather than a developer library, but the same bandwidth math applies: fewer replicated parts means smoother public servers.
