Import

These settings are applied by RapidPipeline 3D Processor to assets on import.

General Import Settings

These settings are applied to all input data, regardless of file format.

Convert Z-Up to Y-Up

Convert Z-Up to Y-Up will rotate the whole asset 90 degrees on the world X-axis.

tip

The asset pivot can be edited with the 3D Edit function Center Object to center, rearCenter, bottomCenter, or topCenter.

Clean Up Animation Data

Fixes animation data by summing all skin weights for each vertex to 1.0, and assigns all weights with zero strength to bone 0.

Normal Map Y Flip

Inverts the green channel of all normal maps. If the bump maps look indented instead of out-dented, this option can help fix them. DirectX uses the Y-down convention as shown on the left, while glTF uses the Y-up convention as shown on the right.

USD Import Settings

These settings are applied to all USD file imports.

USD Import Profile

Defines how input USD files are interpreted. There are two options: generic and arkit.

USD Purpose

Defines the purpose of rendering a prim, used to control render visibility and classify prims into visibility categories. The default string is render, but this can be replaced with another string as needed.

CAD Import Settings

These settings are applied to all CAD file imports. When any of these settings are altered from the default, then the CAD file will be re-imported from the original input file and the new settings will be applied.

Tessellation Resolution

Imported CAD surfaces are tessellated to fine by default. Assets can be re-imported and tessellated to medium or coarse resolution if desired.

CAD Remove T-Junctions

This setting attempts to remove T-junctions after tessellation has been completed. This is currently an experimental feature.

CAD Sewing Tolerance

Tolerance for the sewing operation on the b-reps before tessellation.

Minimum 0, maximum 1,000,000,000,000.

A setting of 0 will disable the function.

Discard Properties on Import

Properties of the 3D assets can be discarded on import.

Discard Cameras

All cameras will be removed from the 3D assets.

Discard Lights

All lights will be removed from the 3D assets.

Discard Animations

All animations will be removed from the 3D assets. Assets will show the state at frame zero.

Discard Morph Targets

All morph targets will be removed from the 3D assets.

Discard unused UV sets

All texture coordinates which are not referenced by any textures will be removed from the 3D assets.

Import Material Settings

Import Material Defaults

Materials can be assigned default properties, which are applied on import if the material model doesn't define default properties already.

Import Default Base Color

Materials can be assigned a default base color.

Note this color has four components: red, green, blue, and alpha.

Import Default Metallic

Materials can be assigned a default metallic value.

Minimum 0, maximum 1, default 0.

Import Default Roughness

Materials can be assigned a default roughness value.

Minimum 0, maximum 1, default 0.5.
