NeuroMechFly / FlyGym, NeLy-EPFL. Apache-2.0. Pinned revision c7affce924cb1c6add16619adf83be5c6b223e89 Original research: https://doi.org/10.1038/s41592-022-01466-7 and https://doi.org/10.1038/s41592-024-02497-y This exhibit adapts the original mesh assets and anatomical hierarchy. Browser dynamics, base assistance, materials, controller and UI are modified; not a validated reproduction or endorsement. Full modification list in model.json. No brain/connectome dataset included. v4 adds two illustrative proboscis hinges, scripted feeding/sensory states and artistic rendering effects. These are NOT part of the upstream validated controller. Original mesh assets remain under ../nmf-v3/.
