6000.3.27f1 Release Notes

Improvements

• Asset Import: Improved the security of model import by updating the bundled Autodesk FBX SDK to 2020.3.11, addressing two buffer-overflow vulnerabilities in FBX file parsing. (UUM-155199)

API Changes

• Graphics: Added: Added Graphics.disableDepthAndStencilBuffers, a read-only property that returns whether Disable Depth and Stencil Buffers is enabled in Player Settings.

Changes

• Physics 2D: "PhysicsComposer.AddLayer", "PhysicsComposer.ToPolygons", "CircleGeometry.ToPolygons" and "CapsuleGeometry.ToPolygons" now log the standard validation warning instead of throwing "ArgumentOutOfRangeException" when given no geometry, fewer than three vertices or an invalid "curveStride". (UUM-156367)
