Other platforms are not supported in this pre-release. Please use the v24.08 release for Windows and Linux.

v24.03

March 2024 release includes, new non-recursive rendering architecture. Expected speed up of around 2x versus recursive rendering.

Also includes upgrade to support MaterialX 1.38.8 and USD 23.08.01

v23.07

A variety of new features and improvements including:

• Support for multiple distant lights (see TestMultipleLights unit test)
• Changes in the MaterialX code generator to support "data driven materials". Rather than assume a fixed set of material parameters, Aurora will generate a set of material properties based on the contents of MaterialX file that can be modified directly without changing the MaterialX document. (see TestMaterialX unit test)
• Added a custom USD ARResolver for doing some asset processing operations. The ImageProcessingResolver will accept URIs with the imageProcessing and pre-process the resulting data before passing to the Hydra render delegate.
• Implemented material emission (see TestMaterialEmission unit test)
• Transfer buffers via temporary upload buffer on upload heap for faster performance.

Aurora release v23.03

Various build script improvements including:

• Builds the usd_view Python application which can be run directly from the build folder with the Aurora render delegate
• Added version detection to installExternals.py
• Refactoring externals folder layout
• Support multi-configuration builds with CMake
• Linux build fixes
• Security updates in externals versions

NOTE: Requires rebuilding the installed externals with the installExternals.py script as described in README.md
