{"data":{"id":"21870","slug":"vfx-mesh-library-tracer-streak-3e6acadc","title":"Tracer streak (VFX Mesh Library)","summary":"A long lozenge tracer with a hot head bead, a bright nose cap and two thin outrider wisps.","description":"A tracer round for fast fire. The main streak is a swept lens section that swells behind the head and pinches at both ends, the head carries a stretched bead and a small lathed nose cap, and two thinner wisps run alongside it. Bounding size 0.12 by 0.11 by 0.93 m, metres, +Y up, +Z forward. Origin: free. The origin is the centre of the projectile body, on the travel axis, so a developer places this mesh by the point the effect emits from rather than by a base. The geometry surrounds it, reaching 0.06 m below and 0.06 m above the origin. Opaque solid geometry throughout: this pack uses no alpha blending and no transmission, so the silhouette and the emissive material carry the read. Static mesh with no animation clip, no skinned rig, no collision and no navigation data.","status":"published","url":"https://3dassets.dev/assets/vfx-mesh-library-tracer-streak-3e6acadc","cdnUrl":"https://cdn.3dassets.dev/assets/21870/v1/model.glb","downloadUrl":"https://3dassets.dev/download/vfx-mesh-library-tracer-streak-3e6acadc","thumbnailUrl":"https://cdn.3dassets.dev/assets/21870/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/21870/v1/poster.webp","blurhash":"UFBWJD-;EQogjED*M|xZ00D*-ns+XA~W-pIW","category":{"slug":"effects-primitives","title":"Effects & Primitives"},"tags":[{"slug":"sci-fi","title":"Sci-Fi"},{"slug":"stylized","title":"Stylized"},{"slug":"kit","title":"Kit / Set"}],"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":30024,"triangles":588,"vertices":1764,"meshes":2,"materials":2,"textures":0,"animations":[],"boundingBox":{"min":[-0.0549944738355818,-0.05501220567504287,-0.44999998807907104],"max":[0.06099447481905844,0.05501220567504287,0.48249998688697815]},"sizeMeters":[0.116,0.11,0.932],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-07T17:31:26.147Z","updatedAt":"2026-09-07T17:31:26.237Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/21870/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function TracerStreakVFXMeshLibrary(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/21870/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/21870/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/21870/v1/model.glb\" alt=\"Tracer streak (VFX Mesh Library)\" camera-controls auto-rotate></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/21870/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.","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)","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/21870/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
