Environment variables¶

HENAD_REQUIRE_GPU=1

Turns "no adapter on this machine" from a silent test skip into a failure. CI sets it on Linux, macOS and Windows. Run the GPU tests with it set before treating them as passing.

HENAD_DUMP_WGSL=<dir>

Writes every shader the engine compiles to <dir>/<label>.wgsl. Shared WGSL reaches the compiler through #import and resolves at build time, and a dumped file therefore shows the assembled source behind a validation error.

EGUI_INSPECTION=1

With --features inspection, opens the app's inspection port on 5719. The port exposes the live widget tree.
