A fast, lightweight texture viewer and converter for game assets — with optional AI upscaling.
- Open & save textures: BLP, BMP, DDS, JPEG, PNG, TGA — plus read-only support for Blizzard TEX (Diablo III/IV).
- Image viewer with zoom, pan, per-channel RGBA filtering, mip level selection, and auto-detection of normal maps and ORM textures.
- Texture details — dimensions, pixel format, mip chain info, and automatic texture kind classification (Diffuse, Normal, ORM, etc.) with manual override.
- Mipmap generation — one-click regeneration that respects texture kind (normal maps get renormalized, PBR textures keep correct properties).
- Batch conversion — convert entire directories at once, multi-threaded, with per-format filters and per-kind DDS targeting.
- CASC browser — open Blizzard game archives directly and browse/extract textures, including full Diablo IV TEX support.
- Save options — format-specific settings (BLP encoding & dithering, DDS format, JPEG quality), mipmap generation on save, and preferences remembered across sessions.
GPU-accelerated texture upscaling powered by Real-ESRGAN via Vulkan compute. Available models:
- realesrgan-x4plus — general-purpose 4× upscale
- realesrgan-x4plus-anime — anime/stylized 4× upscale
- realesr-animevideov3 — 2×, 3×, or 4× upscale
Upscaling can be applied to individual textures or as part of a batch conversion pipeline. Requires building with WHITEOUT_ENABLE_UPSCALER=ON and a Vulkan SDK.
Requires CMake and a C++23 compiler.
cmake -S . -B build
cmake --build build --config ReleaseFor AI upscaling support (optional):
cmake -S . -B build -DWHITEOUT_ENABLE_UPSCALER=ON
cmake --build build --config ReleaseThis requires the Vulkan SDK. Run scripts/download_models.ps1 to fetch the model files.
