Ocarina anti-aliases every frame with its own SMAA in three compute passes after the bloom composite. The new aa setting (nx2navi.ini aa, the Screen tab's Anti-aliasing row) keeps that by default. off, fxaa and smaa leave out the game's edge and weight passes and replace its composition with a pass of our own that writes the same square-rooted RGB9E5 words into the scene target: a plain copy, an edge smoothing written here, or the SMAA reference implementation with its area and search textures (MIT). taa is DLSS or FSR 3.1 at the scene's size, which the row sets through the upscaler; while either runs, the game's SMAA stays whatever aa says. The game's passes are known by a hash of their guest code. The shader build now also rebuilds a header when a file its source includes changes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
