menu_blend_capture.sh counted two DOWNs to reach EXTRAS, which is wrong twice over -- EXTRAS is the fifth item, and on 2026-08-31 four DOWNs landed on OPTIONS because one press was dropped. It now presses until the cursor stops moving, which needs no item count and no row calibration. Its title deadline follows the same change as title_blend_capture.sh, 1200 s not 420. ui_blend_map.py takes a comma-separated build list, because the live title is TWO builds composited -- 4 draws the art, 2 draws the PRESS (A) plate -- and a one-build size table cannot name the elements of a title capture. frame_alpha_census takes its builds from argv for the same reason.

"""Which UI element is drawn with which BLEND state — from a Canary UI draw log.
|
|
|
|
ui_blend_map.py <xenia_re_ui_draws_NN.log> [--build 5]
|
|
|
|
Canary's `CaptureUiDrawForRE` (patched 2026-08-31) logs RB_BLENDCONTROL0 per
|
|
draw. The log does not name elements, so a draw is identified by the PIXEL SIZE
|
|
of its quad: the vertices are in NDC, and (x_max-x_min)/2*1280 by
|
|
(y_max-y_min)/2*720 is the on-screen size, which is matched against the sprite
|
|
dimensions read straight off the disc.
|
|
|
|
CONTROL, and it is not optional: GP_TITLE build 5 draws two rotated sweep
|
|
strips whose heights were measured independently in
|
|
docs/re/data/title-sweep-drawn-at-rest.txt as 1134 and 1303 px. If this script's
|
|
NDC->pixel conversion does not reproduce those two numbers, its sizes are wrong
|
|
and every identification below them is worthless. It prints the check.
