Browser-based 3D asset workflow

Online 3D Texture, EXR, HDR, and UltraHDR Tools

3DKit Online provides focused tools for texture channel packing, channel extraction, EXR/HDR processing, and UltraHDR image workflows. Each tool runs in the browser so artists and technical teams can validate files, export assets, and iterate faster without installing desktop software or uploading source textures to a server.

No-upload workflow
Core tools process assets inside the browser, which is useful for proprietary game art, lookdev tests, and quick technical validation.
Built for PBR and HDR tasks
The current toolset covers texture channel packing, RGBA extraction, EXR and HDR inspection, tone mapping previews, and UltraHDR JPEG workflows.
Useful for artists and tech art
Teams working in Unreal Engine, Unity, Blender, WebGL, and asset pipelines can use these tools for quick conversions and checks.

Common use cases

  • Pack AO, roughness, and metallic maps into ORM, RMO, or RMA textures for UE5, Unity, and Blender workflows.
  • Extract RGBA channels from source textures to rebuild masks, debug authoring issues, or prepare grayscale maps.
  • Open EXR, HDR, and UltraHDR image files online to inspect data, preview tone mapping, and export derived outputs.
  • Run batch operations when you need repeatable texture processing across multiple assets.

How teams use 3DKit Online

  1. Open the tool that matches the asset task, such as texture packing, channel extraction, or HDR image review.
  2. Load source files, adjust mapping or preview settings, and validate the result in the browser.
  3. Export the processed asset or move to a related batch tool when the workflow needs higher throughput.
