Description

Port Orca OrcaSlicer#16153 the Edge way: genuine BambuStudio projects log setting substitutions instead of popping show_substitutions_info. Gated on the BambuStudio generator stamp, not From_BBS && file_version > 2.3.2.

Upstream: merged 9a9285a8, Oct 8 10:33 PM CT — OrcaSlicer#16153

Edge baseline: 809c69ef6e8d4a791d42f4913c25af3ab9ddfd35 (re-checked origin/main before branching).

Why not upstream's condition (D-13a, required)

Edge's _handle_end_metadata sets m_is_bbl_3mf (→ En3mfType::From_BBS) for BambuStudio-*, and SLIC3R_APP_NAME-* (Edge's own files), and Snapmaker_Orca-*. Edge's version is 2.4.5.x > 2.3.2, so From_BBS && file_version > 2.3.2 would also silence substitution dialogs for Edge's and Snapmaker Orca's own projects.

Did not add an En3mfType value (== From_BBS checks at L12256 log / L12524 translate_old would silently change).

Ported

• _BBS_3MF_Importer::m_is_bambu_studio_generator, set only in the BambuStudio- branch.
• Trailing defaulted bool *is_bambu_studio = nullptr on load_bbs_3mf / load_model_from_file / Model::read_from_archive so CLI (src/Snapmaker_Orca.cpp) and existing tests keep compiling.
• log_substitutions overloads above Plater::priv::load_files.
• L12550 (project-embedded presets) and L12609 (config_substitutions): log if BambuStudio, else dialog.

Skipped

• D-13b: unrecognised-keys info log (Edge has no dialog there to replace).
• D-13c: do not silence Snapmaker Orca projects.
• Edge's "newer 3mf version" dialog (L12440–12468) left alone.
• L12956 show_substitutions_info is the read_from_file / STL-adjacent path, not the archive project load. Left alone.

G-code

None.

Overlaps

• Draft Keep per-volume settings when adding a 3MF (Snapmaker #962) #350 (Snap Fix: modifier/part settings lost when importing (Add) a 3MF (#961) Snapmaker/OrcaSlicer#962, 3MF add keeps volume settings) edits the same load_files near the reset branch. Adjacent-hunk conflict; whichever lands second rebases. This PR does not modify Keep per-volume settings when adding a 3MF (Snapmaker #962) #350.

Screenshots/Recordings/Graphs

N/A.

Tests

• tests/libslic3r/test_3mf.cpp: Edge-stamped file → flag false; BambuStudio-02.03.00.70 → true; Snapmaker_Orca-2.2.0 → false.

Owed:

• Edge CI
• MSVC Rel+Debug
• Catch2: libslic3r_tests "[3mf][Regression]" (new generator-flag case)
• slice_compare: N/A
• Manual: open a real BambuStudio 2.x project → no substitution dialog, substitutions in the log. Open an Edge project with an unknown key → dialog still shows.

Fast-lane build and test (2026-10-12)

Built and tested together with the other fast-lane PRs on test/cursor-fastlane (head 558f0e3b93): origin/main 2fe16dac57 with #437, #401, #402, #398 and #404 merged. Ninja + unity + PCH build (agent_build.sh), test copy at C:\Dev\EdgeSlicerTest\fastlane.

• libslic3r_tests: 2026 cases, 2023 pass + 3 expected failures (the standing ones, unchanged). fff_print_tests: 394 cases, all pass (47303 assertions). slic3rutils_tests: 1007 cases, all pass (12815 assertions).
• Identity gate: 25 CLI slices (X1C and U1 cubes, Benchy, Bunny, Voron cube, OrcaCube, stringhell, KSR, tolerance test, 4-tool and 2-colour models, normal and tree supports, vase cubes, by-object, four H2D project plates, a draw-cut project) against the main install 20261011-1724-598616272d (no src/libslic3r or profile change between it and 2fe16dac57). Every G-code file differs from the baseline in exactly one line, the ; generated by ... on <date> stamp. The baseline sliced twice is identical the same way.
• This PR: The BambuStudio generator flag is set only for a BambuStudio Application stamp passes (43 assertions).
• Fixes made in this pass: (1) the test's stamp lambda did not capture path, so test_3mf.cpp did not compile (C3493); (2) the gate is now from_bambu_studio && file_version > Semver(2, 3, 2), as in Orca 16153 (OrcaSlicer only tagged its own 3MFs after 2.3.2, so an older BambuStudio-stamped file may be an Orca project and keeps the dialog). The Edge-specific stamp test stays, because Edge stamps its own projects From_BBS too.
• Merged origin/main and Harden AMF metadata and 3MF cyclic component walks #398 (conflict in tests/libslic3r/test_3mf.cpp: both PRs appended a test at the same spot; both kept). Merge Harden AMF metadata and 3MF cyclic component walks #398 first; head 6665a0ea14.
• Owner check: open a BambuStudio 3MF that used to pop the substitution dialogs; now only a log line (warning level, Loading <path>: ...) and no dialog. An Edge project with an unknown key must still show the dialog.
