Using the command line tool via terminal is a good mechanism to convert one shader at a time. There are two scenarios where you may want to convert your shaders via command line. Now, I'll walk you through how to use the Metal shader converter. It also supports compute shaders, as well as more recently introduced ray tracing stages and shaders and amplification and mesh shaders. Using Metal shader converter, you can convert your shaders for the traditional graphics pipeline including tessellation and geometry shaders to Metal libraries. You can do this because of the rich feature set of Metal shader converter, which supports all the traditional and modern shader stages of your existing DXIL shaders. It also enables you to leverage advanced features of Apple GPUs. As a result you will have reduced shader asset build times. Converting from DXIL to Metal IR is very fast because Metal shader converter performs the conversion at the binary level. You use it alongside the open source DXC compiler tool to build an end-to-end shader pipeline. Metal Shader Converter provides a robust feature set to improve the experience of converting your shaders to Metal. Use the new tool to convert your existing shaders to Metal libraries that you then ship with your game. The Metal libraries generated are the same as those generated from the Metal compiler allowing your converted shaders to natively integrate with the Metal API. This simplifies your shader pipelines and allows you to package the generated Metal libraries directly in your bundle, avoiding on-device generation of Metal IR. If you are a new comer to the Mac, you now have Metal Shader Converter. However, when coming from another API and shading language, you need a way to get them to Metal. You should always aim to generate your Metal libraries using the Metal compiler toolchain ahead of time. That Metal IR is stored as a part of a Metal library. Metal provides you with tools necessary to generate Metal IR from your Metal Shading Language ahead of time. The Metal compiler toolchain helps you compile the shaders that power your game and Metal now makes that easier than ever.Ĭreating the Metal IR on device is suboptimal because it adds compilation overhead before the GPU can do the work you need it to do. This session focuses on your shaders and how to improve their flexibility and speed with some of the new Metal compiler tools, including new ways to convert your shaders to Metal intermediate representation and how to avoid on-device compilation by finalizing GPU binaries during your games' build time. The first session, covers how you can evaluate your game and "make a game plan". This session is the second part of a 3-part series on bringing your high-end games to Mac.

And once you're ready to level up, check out “Bring your game to Mac, Part 2: Render with Metal" from WWDC23. We'll also show you how to reduce app launch time and stutters by generating GPU binaries with the offline compiler. Find out how to build a fast, end-to-end shader pipeline from DXIL that supports all shader stages and allows you to leverage the advanced features of Apple GPUs. Bring your game to Mac, Part 2: Compile your shadersĭiscover how the Metal shader converter streamlines the process of bringing your HLSL shaders to Metal as we continue our three-part series on bringing your game to Mac.
