Start by pressing P in preview mode to check FPS, draw calls, triangles, and entities against the parcel-based limits. Then apply targeted fixes: pool entities, reuse one GLB across many entities, add LOD swapping, compress textures to power-of-two sizes, and throttle expensive systems.

Triangles are limited to 10,000 per parcel and entities to 200 per parcel, scaling linearly. Materials, textures, and height scale logarithmically with log2(n+1). File limits are 15 MB per parcel, 300 MB total, and 50 MB per individual file.

Default to one shared GLB referenced by many entities, since the engine dedups downloads and memory by source. Only merge meshes in Blender when many small static props are always co-visible and measurements show renderer count is the bottleneck, since merging sacrifices per-object culling.

Stutters come from creating entities per frame or spawning many copies at once without preloading. Use object pooling for dynamic entities and AssetLoad to preload assets before bursts, since building copies costs a frame even when the asset is already resident.

Use power-of-two dimensions with a maximum of 1024x1024, since the asset bundle converter downscales anything larger. Use 512x512 for most props, 1024x1024 for hero pieces, and 256x256 for UI elements, preferring WebP or atlases to reduce memory.

Use AssetLoad only for assets not needed at startup, such as models or sounds that appear later or on interaction. Preloading makes later use instant but never frees memory, and assets needed immediately at scene start gain no benefit from it.
