# M16-GAP-00042 Status

status: done
task: DISPLACE modifier LOCAL_EXACT slice
updated: 2026-08-20 America/New_York

scope: DISPLACE modifier direction, strength, level, space, and texture mapping for `mesh:WebGapDisplaceObjectMesh`.

evidence:

- Desktop fixture exposes `WebGapDisplace` with Z direction, strength 0.75, mid-level 0.25, global space, and global texture mapping; save/reopen is exact.
- WASM/Main exposes the same modifier parameters from the same fixture; save/reopen is exact.
- Malformed Blend input is rejected without mutating Main.
- `build_blender_5.2.0/bin/blender ... M16-GAP-00042.py`, `npm --prefix web run test:generated-gap -- --task M16-GAP-00042`, and `node tools/web/check-generated-gap.mjs --task M16-GAP-00042` exited 0.

knownRisk: Full evaluated displacement texture sampling and editor mutation remain outside this metadata/local-exact modifier slice.
