This is a custom rigged Armored Core mecha model, set up for use in Blender 4.0. The rig includes specific articulation for the weapon and body parts, allowing the pilebunker's blade to be moved back and forth without misalignment issues. Additionally, the core's overboost flaps and the shoulder flaps can be opened to reveal the internal compartments. This model is a custom assembly based on FromSoftware assets.
