Coming to Steam

From raw assets to
production-ready packages

Drop a folder with 25 models and 125 textures. Smelt detects every material, maps every channel, and exports a production-ready package for your target platform - in seconds, not hours.

How It Works

Three steps. Zero configuration.

No manual sorting. No naming conventions to memorize. Drop your files and let Smelt handle the rest.

1 DROP

Drop

Drag folders, ZIP/RAR/7Z archives, or individual files into Smelt. 3D models and textures in any format and folder structure are recognized automatically.

2 DETECT

Detect, Group & Preview

Smelt's token engine identifies PBR channels with confidence scoring and groups textures into materials. Preview under real PBR lighting, then fine-tune with the dedicated filter editor - stackable, non-destructive, with a live before/after split view.

3 EXPORT

Export

Pick your target from 7 export destinations. Smelt handles texture format conversion, resolution scaling, channel packing, and height-to-normal generation automatically - then saves to your asset library for reuse.

Features

Built for real asset pipelines

No more renaming files, guessing which texture belongs where, or rebuilding folder structures by hand. Drop your assets, pick your target, export. Smelt handles detection, grouping, channel packing, and format conversion - you handle the creative work.

Smart Import

Drop files in any format or folder structure - even ZIP archives. Token-based PBR detection with confidence scoring.

Real-Time PBR Preview

See materials under realistic lighting before exporting. Catch channel issues before they hit your project.

Dedicated Filter Editor

Stackable, non-destructive filters with a draggable before/after split view and live 3D preview.

Channel Packing

Combine roughness, metallic, and AO into ORM - or configure your own RGBA slots per target.

Height-to-Normal

Generate normals from height maps with adjustable intensity. OpenGL or DirectX output.

Resize & Convert

Scale 16K → 1K without flinching. 9 texture formats - PNG, JPG, TGA, DDS, EXR, HDR, PSD, BMP, TIFF.

Native Material Files

Unity, Godot, and Blender exports open with full material setup - no plugin, no manual wiring.

7 Export Targets

Godot, Unity, Unreal, Blender, Maya, 3ds Max, Generic. Free companion plugins for the last three.
