The shaders are ported almost verbatim (see src/shaders/). The only changes are renaming engine-reserved identifiers and using PlayCanvas's built-in attribute/uniform names (aPosition, matrix_viewProjection). Both cameras run with GAMMA_NONE / TONEMAP_NONE so colors match the original's raw output.
GLSL) for every texture fetch the ray tracer makes from non-uniform control flow — WGSL forbids implicit-derivative sampling there. The pool tiles therefore sample at LOD 0 (no mip filtering).
