Technical Animation Challenges on Mobile Titles

" summary

Mobile skeletal meshes hit a hard 75 bone limit, so the solution separates characters into modular meshes with an identical shared bone hierarchy and uses Unreal Engine’s Copy Mesh from Reference to mirror animations between base and gadget meshes. Weapon grips use retargeted animation plus IK offsets stored in tables or a universal hand modeled once for all characters. Procedural extras use AnimDynamics (measured at about 0.02 ms per node) and Sub-Anim Instances for minimal overhead.
