A new month and as usual, we have a new release for you with new features and bug fixes. If you want to know what we are planning to do in the future, have a look at our roadmap. You can even vote for your favorite features.
If you are already running The Machinery, this new release should pop up in your Downloads tab. Otherwise, get it from our download page and have a look at this quick introduction video. We are also working on two books about The Machinery. One is an overview of the engine and the other one a collection of tutorials on how to do specific things. Note that both these books are still works in progress.
If you find bugs in this release or have requests for specific features, post them to our issue tracker. For more general discussions, hit us up on GitHub discussions or Discord.
Key highlights in this release are:
And as always, we also have a number of smaller updates.
We’ve introduced versioning of The Machinery APIs. Now, when you request an API like this:
tm_ui_api = tm_get_api(reg, tm_ui_api);
your request will be bound to the current version of the API. When your plugin is loaded, it will check if it can find a matching version of the API. If not, an error message will be printed and the plugin will be disabled.
This ensures that we can continue to develop The Machinery while providing maximum compatibility with existing plugins.
For more information about API versioning and the plugin system, see this blog post.
We’ve added a new component that implements screen-space reflections (SSR). The implementation is based on the slides from Stochastic Screen-Space Reflections presented at Siggraph 2015. In addition, we have also added support for local parallax corrected image based lights (IBLs). When used together, they form the foundation of a full reflection pipeline with SSR falling back to local IBLs falling back to a global sky IBL.
There’s still work to be done to increase the quality and improve the performance as well as adding support for raytraced reflection as a higher-quality fallback to prebaked IBLs when running on GPUs with ray tracing support.
The Machinery now compiles for ARM CPUs. In particular, we compile natively on Apple silicon (the new MacBook CPUs). Note that we do not yet have a Metal backend, so only the command-line tools currently run on OS X (but everything compiles).
