This is a fan-made character model of RO635 from Girls' Frontline. The model is rigged, weighted, and textured, but not fully UV mapped. It contains 42,000 vertices and 84,000 triangles when using an outline solidify modifier.
The character rig features an IK/FK switch for the limbs and spine, and isolated rotation toggles for the head and limbs. Facial expressions are controlled via bone-driven shape keys, offering options for eye sparkles, blush, blinks, and various mouth poses. Hair, lanyard, and chest bones are set up to work with the free Wiggle Bone addon.
