A promising alternative is Shady, an IR for lowering arbitrary code to Vulkan SPIR-V, and Vcc, a front-end for compiling C++ to Vulkan shaders. Reducing the number of languages in the project is a massive potential benefit, and it might be worth integrating even with some upfront difficulties.

Playnote currently uses Slang for shaders. It's something of a sinking ship, though; the last months have seen a concerning freefall in code quality, with more miscompilations and ICEs than ever before. A promising alternative is [Shady](https://github.com/shady-gang/shady), an IR for lowering arbitrary code to Vulkan SPIR-V, and [Vcc](https://shady-gang.github.io/vcc/), a front-end for compiling C++ to Vulkan shaders.
