Supported environments

OS

• Linux
• Macos
• Windows

Engine

• godotengine/godot 4.3.0

Nim compiler

• nim-lang/nim 2.0.0 or higher

  Macos

  Use Nim installed via Homebrew, not choosenim. Due to the execution environment of Godot itself, a native AArch64/ARM64 build of Nim is required, and that choosenim installs a x86_64 build emulated via Rosetta.
