Runtime File Importer lets your players bring their own files into your game, and lets your game save files back out, without the editor and without writing a line of C++. Pick a file with a native file dialog, drop it onto the game window, or download it from a URL, and turn it into a real Unreal asset in one node: a Sound Wave, a Static or Skeletal Mesh with its animations, a Texture, a playing video, a Data Table, a Font or a formatted document.

Everything is exposed to Blueprints through one Game Instance Subsystem. Every node that reads files, downloads or does heavy work comes in two versions: a simple synchronous node, and an Async node with On Progress, On Success and On Failure outputs that runs in the background, so your game never freezes on a large file.

AUDIO

• Import MP3, WAV, FLAC, OGG Vorbis, OGG Opus, AIFF and raw PCM into a playable Sound Wave.

• Export any sound to WAV, OGG Vorbis, FLAC or raw PCM, or convert audio files directly.

• Playback control: volume, pitch, looping, pause, rewind, playback time and percentage, live amplitude.

• Read duration, format and metadata (title, artist, album, ...), and get waveform data to draw audio visualizers.

• Streaming Sound Waves: append audio while it plays.

• Microphone capture: list input devices and record the player's microphone into a Sound Wave.

• Sound settings as Blueprint variables: attenuation, concurrency, submix, source effects and more.

3D MODELS, SKELETONS & ANIMATION

• Import FBX, OBJ, glTF, GLB, STL, PLY, USD (USD, USDA, USDC), USDZ, Alembic and Collada.

• Static meshes and skeletal meshes with materials, textures, vertex colors, multiple UV channels, skeletons, skin weights, morph targets, animations and collision / physics assets.

• Spawn the result as a Runtime Mesh Actor in one node and play its animations.

• Export any Static Mesh, Skeletal Mesh, Animation, Physics Asset or whole Actor to FBX, OBJ, glTF, GLB, STL, PLY, USDA, USDZ, Alembic or Collada, or convert between file formats.

• Convert between Static Mesh and Skeletal Mesh, bake a posed Skeletal Mesh Component to a Static Mesh, create physics assets.

• Edit meshes at runtime: materials and material slots, sections, shadows, LOD settings, sockets, bounds, simple and complex collision (box, sphere, capsule, convex) and Nanite.

• Mesh Description nodes for vertex-level editing: positions, normals, UVs, colors, transforms, generated UVs, recomputed normals and tangents.

• Inspect any mesh, skeleton, animation or physics asset: triangle and vertex counts, bones, sockets, curves, notifies and more.

IMAGES & TEXTURES

• Import PNG, JPEG, BMP, TGA, EXR, HDR, TIFF, ICO, ICNS and GIF as Texture 2D, Texture Cube or Render Target.

• Export textures and render targets to PNG, JPEG, BMP, TGA, EXR, HDR or GIF.

• A full image editing toolkit on the Runtime Image object: resize, crop, rotate, flip, blur, sharpen, color adjustments, grayscale, invert, channel swizzle, draw images onto images, make a color transparent, generate normal maps and more.

• Change texture settings at runtime: filtering, address mode, sRGB, compression, LOD bias and group, mipmaps.

• Create a ready-to-use material from any texture.

VIDEO

• Play MP4, MOV, AVI, MKV, WebM, WMV, GIF, MPEG-TS and MPEG files or URLs into a texture, with sound.

• Play, pause, stop, seek, loop, playback rate, volume, track selection, playback time and progress.

• Capture single frames, thumbnails, or extract every frame as images.

• Record the game screen, or any texture, render target or video, to MP4 or AVI, including the game's sound.

• Export image frames to MP4, AVI, GIF or an image sequence, or convert video files.

TEXT, DATA & LOCALIZATION

• Read and write text in any encoding (UTF-8, UTF-16 and more), with automatic encoding detection.

• Runtime Data object: one Blueprint-friendly way to read, edit and write JSON, XML, CSV, TSV, INI and YAML, and to read Excel (XLSX) and OpenDocument (ODS) spreadsheets.

• Import Data Tables at runtime from CSV, JSON, TSV, XML, INI, Excel or OpenDocument (great for moddable game data), and export them back.

• Import String Tables from CSV, spreadsheets or JSON for runtime localization and mod text.

• Subtitles: import, export and convert SRT, WebVTT and ASS/SSA, find the subtitle at any time, shift timings.

• Regex match, find and replace, Base64, line endings, markup to plain text.

DOCUMENTS

• Open Word (DOCX), OpenDocument Text (ODT), PDF (text), HTML, Markdown, RTF and plain text documents.

• Runtime Document Viewer: a UMG widget that shows formatted documents with pages, scrolling, fonts and colors. Drop it into any widget Blueprint.

• Google Docs, Sheets, Slides, Google Drive and Dropbox share links are turned into download links automatically.

FILES, DIALOGS, DRAG & DROP, DOWNLOADS

• Native Windows Open File, Save File and Open Folder dialogs, with filters by file type.

• Runtime File Drop Zone: a UMG widget that accepts files dragged from Windows Explorer onto the game window.

• Download any file over HTTP or HTTPS with progress.

• Load and save raw bytes, read file info, detect a file's type from its contents.

ARCHIVES & FONTS

• List, read, extract and create ZIP archives (including ZIP64), from files or from memory. Compress and decompress bytes with GZip, Zlib or raw Deflate.

• Load TTF, OTF, TTC and WOFF fonts at runtime and use them in UMG and Slate.

BUILT FOR GAMES

• Works in packaged games (Development and Shipping), not just in the editor.

• Blueprint-first: 585 nodes, including 135 async nodes and 23 events, all reachable from the Runtime File Importer Subsystem. Full C++ access too.

• Clear error messages on every node, so you can show the player what went wrong.

• No external programs or DLLs to install: everything the plugin needs is compiled into it.
