Note
Required Library: .NET framework 4.5+ or .NET standard 1.3+ in Unity. API Compatibility Level .NET 4.x (Net Framework) is no longer required but is still recommended because it provides better performances than .NET 2
To select the API Compatibility level, go to Edit > Project Settings > Player > Other Settings :
Known Limitations#
Warning
Please read and review the known limitations before using the connector.
Note
ABI compatibility issues may arise from Boost, TBB, USD versions, and other possible libraries.
Unity components that are not supported will transfer as an xform in the USD Stage.
Exporting Unity Terrain components is not supported; we recommend using Mesh components for Terrain.
Live sync does not support changes to physics components or physics materials being updated Live. A re-export is required.
Baking Global Illumination while in Live Sync will hang the session and sometimes cause a crash.
