First-person AK47 and hands: Ak47 by kursat_sokmen, CC BY 4.0, original at https://skfb.ly/6UEL9. Modifications include in-game coordinates and scaling, material roughness, animation playback speed and transitions, and muzzle effects; sleeves, hand colours, and normal maps were remade for Tsim Sha Tsui, Mong Kok, and PvP mode (Causeway Bay retains original textures), preserving existing geometry, UVs, and rigging. The AK47 held by enemies in Mong Kok Level 4 "Three Alarms" also derives from this model: stripped to the receiver without hands, reduced to approx. 1,900 triangles, colour textures downscaled to 512/256 px, with normal maps removed.
