Exporter Options

Mesh Options

The Mesh section controls geometry-specific export behavior, including tangents, gaussian splats, and round-trip metadata.

Open Exporter Overview Install the Plug-in View Supported Features

The Mesh section: Export Tangents, Gaussian Splats, and Export Quad Topology.

Export Tangents

• Disabled by default
• Writes the TANGENT attribute to the output file
• Enable this when your target runtime depends on authored tangent-space data
• Leave disabled when the target runtime can generate tangents and you want smaller files

Gaussian Splats

• Disabled by default
• Exports GaussianSplatLocator nodes as KHR_gaussian_splatting point primitives
• Requires the companion Gaussian Splat Importer and Exporter for Maya plug-in (GaussianSplatPlugin) and its export bridge to already be available in Maya
• That companion plug-in is Windows only (macOS and Linux are not supported)
• Get the companion plug-in from PolyPulse3D
• If the bridge is unavailable, splat shapes are skipped with a warning

Compress Splats

• Disabled by default; only available when Gaussian Splats is on
• Quantizes allowed splat attributes (rotation, opacity, COLOR_0) for smaller files
• Slight precision loss vs full float attributes - leave off when you need maximum fidelity
• See Gaussian Splats for the full option description

SH Degree

• Default 3; only available when Gaussian Splats is on
• Caps spherical-harmonic lighting bands written to the file (0 = base color only)
• Automatically falls back when the source has a lower degree than requested
• Separate from the Attribute Editor SH Degree slider on the companion plug-in (viewport / Arnold only)
• See Gaussian Splats for the behavior table

Export Quad Topology

• Disabled by default
• Stores Maya-oriented quad or n-gon topology metadata for later re-import into Maya
• Intended for round-trip workflows
• Increases file size and should usually stay off for web/runtime delivery builds
