optimised world models for mp5, double barrel shotgun and both youtooz figurines all were on the rigged setup - skinned meshes and bone hierarchies that do nothing once dropped. - Skinned meshes: 24 -> 0 - bones: 16 -> 0 - Prefab SkinnedMeshRenderers: 14 -> 0 - LOD0 renderers: 7 -> 4 - Meshes: 25 -> 13 also stripped exported tangents/binormals from these plus w_diverak47 (unity recalculates them on import) and cleared the leftover import settings on the fbxs: FBX size 3.55MB -> 1.74MB (-51%).
