Enum BasisTransformation
How to transform from the USD basis (typically right-handed) to Unity (left-handed).
Namespace: Unity.Formats.USD
Syntax
public enum BasisTransformationFields
| Name | Description | Value |
|---|---|---|
| FastWithNegativeScale | Apply a single negative scale and rotation at the root of the scene hierarchy. Fastest, but may introduce additional complications when later exporting. |
0 |
| SlowAndSafe | Transform to left-handed basis by processing all positions, triangles, transforms, and primvar data. While slower, this is the safest option. |
1 |
| SlowAndSafeAsFBX | Transform to left-handed basis by processing all positions, triangles, transforms, and primvar data. It transforms to match the basis transformation of FBX which is from (X,Y,Z) to (-X,Y,Z) instead of the standard (SlowAndSafe option) (X,Y,Z) to (X,Y,-Z). This is not a conventional behavior and this option is here only to allow consistency between geometry importers. |
2 |
| None | Preform no transformation; should only be used when the USD file is known to contain data which was (non-portably) stored in a left-handed basis. |
