Clone the repository at and build the branch tg/luma/luma following the official build instructions. Use our custom build of USDīuilding Luma Pictures' flavor of USD is the easiest option, we provide a set of new features, mostly to usdMaya and usdKatana, none of which are breaking any existing behavior in USD. Our build process is designed to build USD-Arnold as multiple rez packages, so the different components need to be built separately from the main schema.Īt this moment USD-Arnold relies on several customizations and fixes to USD, most of which have their PR and waiting to be merged back. Making sure USD-Arnold works with a base installation of USD.
