A practical workflow for converting GLSL to WGSL, validating results, and catching the common migration issues early.
The fastest way to create bad WGSL is to assume conversion is only mechanical. A good workflow mixes automated translation with deliberate review.
Pick one shader stage and one file first. Verify entry points, uniforms, and outputs before scaling to a whole library.
That makes it much easier to identify whether a failure comes from language conversion, layout assumptions, or downstream runtime setup.
After conversion, inspect bindings, built-in values, texture sampling paths, and stage-specific assumptions. These are common sources of subtle bugs.
Once the output looks reasonable, validate it in the actual WebGPU environment or test harness that will consume the shader.
