Reactor Widow - 28 Animations - 3 LODs - Rigged Creature 3D Model

Reactor Widow is an original six-legged organic predator for game prototypes, creature animation and boss encounters. Includes an editable Blender source, three animated GLB LODs, a separate filament projectile, baked PBR textures and documented animation events.


Creature and animation


Armoured retractable head, articulated mandibles, two three-segment palps, six IK-controlled legs and a segmented abdomen with small emissive organic windows. The locomotion uses a weighted tripod gait.


- 28 named clips at 30 FPS: idle, walk, run, strafes, turns, detection, threat, single-shot and fan-shot preparation/fire/recovery, bite, foreleg strike, guard, hit reactions, stun, phase transition, death and a held final dead pose.
- All locomotion is in place. Move and rotate the creature from your own game code.
- Shared 43-bone deform skeleton across all three LODs, with up to four normalized influences per vertex.
- Blender control rig: 72 bones, including the 43 deform bones, with IK for six legs. Exported clips have constraints and drivers baked.
- Socket_Filament and Socket_Abdomen attachment bones; 43 documented gameplay timing events in CSV. Events require integration in your application.

Downloads


- Blender folder: contains the Final and Export_Check .blend files and textures. The Final includes the three LODs, high-poly source, control/deform rigs, animations, projectile and two presentation scenes.
- GLB folder: all three animated creature GLBs plus Filamento_Proyectil.glb. Includes LOD1, LOD2 and the projectile.
- Extras folder: external 2K/1K texture sets, projectile textures, clip manifest, animation-event CSV, README/README_EN, integration notes, QA and licence/provenance documents.

Rendered preview videos and production scripts are not included in these downloads. The containment room shown in cinematic images is a Blender presentation scene only; it is not included in the GLB files or supplied as a separate game environment.


Technical specifications


- LOD0: 31,758 triangles, 22,359 exported vertices, eight embedded 2048px textures.
- LOD1: 11,971 triangles, 10,644 exported vertices, eight embedded 1024px textures.
- LOD2: 4,444 triangles, 4,626 exported vertices, eight embedded 1024px textures.
- One skinned mesh and two material primitives per creature GLB. Draw-call cost depends on the target engine and render passes.
- Projectile: 768 triangles, one material, four 512px textures. Uses optional KHR_materials_emissive_strength.
- PBR maps: Base Color, OpenGL (+Y) tangent-space Normal, packed ORM (R=AO, G=roughness, B=metallic), Emissive. Source height, separate channel maps and chamber mask also supplied.
- Metre scale. Idle dimensions approximately 1.63m high, 3.10m long and 3.34m leg span. Blender forward -Y/up +Z; GLB forward +Z/up +Y.
- Opaque, single-sided creature materials; no shape keys. The high-poly source remains in Blender only.

Verified compatibility


Blender 5.2.2 LTS: source files opened and all creature GLBs reimported. The delivered validation reports record zero errors, warnings, infos or hints from Khronos glTF Validator for all four GLBs. Godot 4.7.2 import/playback was checked on macOS Apple Silicon in Forward+, Mobile and Compatibility renderers, with all 28 clip durations verified. This is a custom creature skeleton, without an Epic Skeleton or humanoid retargeting setup.


In Godot, disable nodes/use_name_suffixes to preserve Guard_Loop and Stun_Loop names and enable looping for the cyclic clips. glTF does not store a loop flag.


Known limitations — review before purchase


- Unity, Unreal Engine, phone hardware and exported Android/iOS/Windows/Web builds have not been tested. Godot's Mobile renderer was tested on a Mac, not a mobile device. No phone performance or memory claim is made.
- No FBX/OBJ/USD, engine project, collisions/physics asset, gameplay controller, damage logic, root motion or jump animation is included. Apply the projectile and animation events through your own game logic.
- LOD1/LOD2 simplify the head. In some attack/stun clips the palp bases intersect the simplified head sockets, with intersection reach up to about 65mm from the palp joint. Palps do not cross each other; LOD0 bases remain inside their sockets. Visibility at gameplay distance was not measured.
- In Stun_Loop, 13 neck/head membrane triangles compress to about 11% of their original area, visible mainly from below/behind the head. LOD1/LOD2 retain five and 24 single-triangle holes, respectively, not visible from the tested views.
- Some leg sockets penetrate the thorax by up to 3.6mm. The final death pose includes axial femur twist. In Godot, the mesh can reach about 6mm below the floor; direct GLB measurements differ.
- Abdomen scale inheritance can produce cross-section differences up to about 4.2 degrees from the control rig. Animated non-uniform bone scale requires target-engine support.
- Abdomen windows are small and show best in close-ups. GLB emission is static; drive pulsing yourself with the chamber mask and timing events.
- Earlier Blender versions are untested. OpenGL normal maps need a green-channel flip for targets expecting DirectX normals. English README is included; detailed QA/integration documents and some media captions are in Spanish.

All artwork was created for this project. Third-party production tools are documented in the included provenance notes; the tools are not distributed with these format packages.
