A realistic look at what automated shader conversion handles well and where manual review is still required.
Conversion tools save time, but they do not erase platform differences. Knowing the limits makes the output more trustworthy.
It is excellent for reducing repetitive syntax work, comparing equivalent logic across backends, and building migration prototypes quickly.
It also helps teams search, review, and organize shader code when one source language needs to reach multiple targets.
Bindings, built-in semantics, target-specific conventions, and runtime integration details still require human judgment.
The right mindset is to treat conversion as acceleration. The final acceptance test still happens in the destination toolchain and runtime.
