Importing from a hotel wrote the downloaded .nitro to disk untouched, so
official PNG textures stayed PNG and only SWF imports ended up as WebP.
Every Studio import should produce the same format regardless of where the
bytes came from, so both clone and upload paths now run the bundle through
toWebpLosslessBundle.
The helper decodes the texture and re-encodes it with the same VP8L options
the SWF importer uses, so the artwork round-trips bit-for-bit, and lets
createNitroBundle relabel the member and repair the meta.image pointer. A
bundle that is already lossless WebP is returned untouched, making the
operation idempotent and safe to run on re-import. A colour variant that
shares a library keeps the member base name it arrived with.
A texture that cannot be decoded keeps its original format with a warning
instead of failing the import: the bundle is valid, and losing a furniture
item over a codec edge case is worse than a slightly larger texture.
Newly converted .nitro bundles now store their spritesheet as WebP VP8L
instead of PNG, so imports land much smaller without changing a single
pixel. The texture member and spritesheet.meta.image are both labelled
from the actual bytes, never from a caller's assumption.
- encode through sharp with lossless and exact, so colour hidden under
alpha 0 survives; this mirrors ImageSharp's TransparentColorMode.Preserve
- detect PNG/WebP by magic bytes and reject anything the client cannot
render, on create, download and upload paths
- keep the source format when deriving size-32 sheets, scaling composites
and editing metadata, so existing bundles are never silently rewritten
- report fidelity in the studio: the compression panel re-encodes with the
same options the importer uses, so it cannot drift and invent false
warnings, and shows PNG/WebP size estimates
convertSwfToNitro and buildSpritesheet are now async, so the worker, the
main-thread fallback and every import call site await them. PNG stays
supported for existing bundles and icon sidecars are untouched.
Replace classname/name keyword guessing with real data so sit/lay/stand
has zero false positives:
- autoDetectInteraction() now accepts real flags (cansiton/canlayon/
canstandon), logicType, and animation-state count; real data wins and
keywords are only a fallback when no real data exists.
- New furni-real-interaction helper reads the local FurnitureData.json
(highest-revision entries win; a true flag in any duplicate is kept)
and falls back to the official Habbo furnidata.
- interaction_modes_count now uses emulator conventions: dice=6,
gate/teleport=2, roller=1, generic multistate = animation-state count,
chairs/beds=1, plain items=0.
- verifyAndFixInteractionModesCount only touches items with real data
and skips everything else (no keyword overwrites).
- parseNitroBundle falls back to gunzip for gzip-compressed .nitro files.
- Wired through furni-import, upload-import, clone-import, and the nitro
editor auto-detect button.
