NUI Framework
Language
NUI Script V2 is the source format used to describe UI structure for NUIWBP assets inside Unreal Engine.
Language documentation will expand as syntax reference and examples are stabilized.
Source-authored structure
NUI Script V2 exists to make UI structure readable, reviewable, and easier to edit repeatedly. The source describes the UI structure that is compiled inside Unreal.
The language documentation will focus on structure, naming, supported declarations, layout expression, component usage, and diagnostic output.
Diagnostic model
Clear diagnostics are part of the language experience. The goal is to make errors traceable to source and understandable during the compile-and-preview loop.
Future assistance
Because NUI uses structured source, future editor assistance, MCP workflows, and AI-assisted editing can reason about UI structure without requiring creators to leave Unreal Engine.
