Exporter Options

Extensions and Compression

Review the exporter controls that emit optional glTF extensions or compression workflows.

Open Exporter Overview Install the Plug-in View Supported Features

Mesh Quantization

  • Disabled by default
  • Enables KHR_mesh_quantization
  • Useful for reducing vertex storage size
  • Should be tested against your runtime and asset-quality requirements

Draco Compression

  • Disabled by default
  • Enables KHR_draco_mesh_compression
  • Can reduce mesh size significantly
  • The exporter exposes presets and manual quantization controls

Draco Presets

  • Fast: Highest precision, lighter compression
  • Balanced: Default preset
  • High: Stronger compression
  • Maximum: Smallest files, most aggressive settings
  • Custom: Manual control of every slider

Advanced Draco Controls

  • Strip Uncompressed
  • Compression Level
  • Position Bits
  • Normal Bits
  • Texcoord Bits
  • Color Bits
  • Generic Bits

KTX2 Compression

KTX2 settings appear when Texture Format is set to KTX2 Format.

KTX2 Controls

  • Quality: Low, Medium, High, Maximum
  • Format: ETC1S, UASTC, ASTC 4x4, None
  • Supercompression: Zstandard toggle
  • Generate Mipmaps: Auto-generate mip levels

Texture Transform Export

When supported texture nodes contain UV transforms, the exporter writes KHR_texture_transform and registers it as required so the output file explicitly records the transform dependency.
