Premium modern game asset for shooter and survival projects.","description":"A single shot underbarrel grenade launcher whose ribbed barrel slides forward to load, with its own trigger, grip and ladder sight, mounting under a host weapon on an underbarrel rail. Dimensions 0.061 x 0.109 x 0.320 m (X x Y x Z). Origin at the footprint centre with the grip toe on y = 0; the mount port is the top face of the clamp block; metre units, +Y up, muzzle and point toward +Z. Named pivots: pump at (0, 0.0612, -0.1). Connectors: mount underbarrel at (0, 0.0722, -0.03) facing +Y; muzzle muzzle at (0, 0.0612, 0.16) facing +Z. The barrel slides forward along the bore on its own node to load. The latch, the trigger linkage and the safety are modelled and left static. Rigid node-transform clips open, close drive named nodes on their own pivots. No skinning and no skeleton. Blued gunmetal, bright machined steel, dark anodised alloy, black and dark earth polymer, rubber, walnut, brass, copper, leather, olive paint, optical glass, concrete and emissive red, green and warm white for reticles, lasers, tritium and lamps. Physically based flat colours with no texture maps. Original invented design: no real make, model, manufacturer or marking is represented. Free 3D model for Unity, Godot, Unreal, three.js and Blender. No collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/mega-weapon-pack-underbarrel-grenade-launcher-c18eda51","cdnUrl":"https://cdn.3dassets.dev/assets/33008/v1/model.glb","downloadUrl":"https://3dassets.dev/download/mega-weapon-pack-underbarrel-grenade-launcher-c18eda51","thumbnailUrl":"https://cdn.3dassets.dev/assets/33008/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/33008/v1/poster.webp","blurhash":"U58z}W-p4V-._24pD*-:004o.6xu8{_L_LIW","category":{"slug":"weapons-tools","title":"Weapons & Tools"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"realistic","title":"Realistic"},{"slug":"animated","title":"Animated"},{"slug":"modular","title":"Modular"}],"license":{"slug":"cc0-1.0","name":"CC0 1.0 Universal","url":"https://creativecommons.org/publicdomain/zero/1.0/","attributionRequired":false},"contributor":{"username":"3dassets","name":"3D Assets","url":"https://3dassets.dev/u/3dassets"},"stats":{"fileSize":304584,"triangles":10296,"vertices":14732,"meshes":7,"materials":6,"textures":0,"animations":["open","close"],"boundingBox":{"min":[-0.030279243073194007,8.053415492953464e-7,-0.1599999964237213],"max":[0.030279243073194007,0.10881579447336201,0.1599999948963523]},"sizeMeters":[0.061,0.109,0.32],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"claude-opus-5","downloads":0,"publishedAt":"2026-09-08T16:48:42.029Z","updatedAt":"2026-09-08T16:48:42.127Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\nimport { AnimationMixer } from 'three'\n\nlet mixer\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/33008/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n  mixer = new AnimationMixer(gltf.scene)\n  mixer.clipAction(gltf.animations[0]).play()\n})\n\n// Call from your render loop; deltaSeconds is time since the previous frame.\nfunction updateAssetAnimation(deltaSeconds) {\n  mixer?.update(deltaSeconds)\n}","r3f":"import { useGLTF, useAnimations } from '@react-three/drei'\nimport { useEffect } from 'react'\n\nexport function UnderbarrelGrenadeLauncherMegaWeaponPack(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/33008/v1/model.glb')\n  const { actions, names } = useAnimations(animations, scene)\n  useEffect(() => {\n    const action = actions[names[0]]\n    action?.reset().play()\n    return () => { action?.stop() }\n  }, [actions, names])\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/33008/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/33008/v1/model.glb\" alt=\"Underbarrel Grenade Launcher (Mega Weapon Pack)\" camera-controls auto-rotate autoplay></model-viewer>","blender":"# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.\nimport bpy\nbpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/33008/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.\n# Clips arrive as actions; play them from the Dope Sheet > Action Editor.","godot":"# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.\nvar packed := load(\"res://models/model.glb\") as PackedScene\nvar model := packed.instantiate()\nadd_child(model)\nvar player := model.find_child(\"AnimationPlayer\", true, false) as AnimationPlayer\nplayer.play(player.get_animation_list()[0])","unity":"// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,\n// or load it at runtime straight from the CDN:\nusing GLTFast;\nvar gltf = new GltfImport();\nif (await gltf.Load(\"https://cdn.3dassets.dev/assets/33008/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
