Changelog

0.1.8

• Fixed overlapping decal flicker:
  • Back face offset 3 mm.
  • Overlap depth stagger 1.5 mm per layer, capped at 30 mm.

0.1.4

• Added a multiplayer master switch (B by default), action hotkey rebinding, per-player upload limits, remote GIF animation limits, remote spray size in meters, baked GIF atlas transfer and hidden teammate sprays.
• The multiplayer master switch defaults to OFF, so a fresh install starts fully offline; press B to enable it.
• ESC now returns/closes every menu level.
• Cache index now removes duplicate index.tsv entries instead of appending the same source/cache pair repeatedly.
• Fixed orphan .texturecache files not being removed after their source image was deleted. Orphan texture/BC7 caches are now detected by rebuilding the expected cache path set from the current Sprays and Received images.
• BC7 cache writes are now registered in the cache index on both sync and async paths.
• Long GIFs are sampled evenly to preserve their full duration instead of truncating.
• Added a minimum GIF frame delay to stop zero-delay GIFs from playing at 50 FPS.
• Removed the old experimental Steam P2P, compression, host-policy, missing-list and remote cap logic from the transfer layer.

Retained transfer core (not new)

• Source-image transfer, SHA-256 validation and missing-chunk ACK resend were kept from the old transfer layer. They are listed here as retained behavior, not as new 0.1.4 features.

• PNG/JPG now use the managed StbImageSharp decoder on a background thread, then upload raw RGBA on the main thread. This is true background decode instead of main-thread Texture2D.LoadImage. StbImageSharp is licensed under Unlicense OR MIT.

• GIF gallery previews are now asynchronous; the first frame appears after background decode/upload instead of blocking the menu.

• Removed the in-game image deletion key; delete image files in Explorer instead. Missing-image caches are cleaned automatically on startup and gallery refresh.

• GIF spray startup no longer decodes a preview synchronously; pending GIFs use a placeholder and fill in asynchronously. GIF file reads also happen off the main thread.

• Fixed JPG/PNG not appearing after the async change on GTFO's IL2CPP build: UnityWebRequestTexture requires a missing DownloadHandlerTexture(bool) constructor. Fallback now uses async file download + main-thread LoadImage.

• Gallery refresh now cleans index entries for images deleted outside the menu.

• PNG/JPG static material and preview loading is asynchronous; the image cache index also covers static/DXT/send caches.

• PNG/JPG material and preview decoding is now asynchronous (UnityWebRequestTexture), so the main thread no longer performs image decode on first use.

• Added a cache index (Sprays/.cache/index.tsv). Deleting an image from the gallery deletes its GIF/static/DXT/send caches; missing images are cleaned on startup. Legacy unindexed caches are purged once.

• Network transfer compression now detects GIF/PNG/JPEG by file header, not just extension.

• GIF frame dedupe now uses a 64-bit hash instead of a byte-by-byte compare.

• GIF decode dimension limit raised to 4096; added GifMaxFrames (default 120) to bound frame memory.

• Added a bounded in-memory GIF cache with LRU eviction; active sprays/materials are never evicted. New options: GifMemoryCacheMB (default 256) and GifMemoryCacheCount (default 8).

• GIF animation now pauses while its renderer is off-screen (GifPauseOffscreen, default true).

• GIF decoder now merges identical consecutive frames and extends the previous frame's delay, reducing texture count and memory use.

• Image format detection now uses file headers instead of relying only on the extension. GIF content stored under a .png/.jpg name is decoded as GIF; WebP content is reported as unsupported instead of silently failing.

• Horizontal flip is now applied consistently to PNG, JPG and GIF textures. FlipStaticImages keeps its config key but affects all image formats.

• Unsupported WebP images now log a clear warning.

• Menu/README format notes updated.

0.1.3

• Data folders are now created next to SprayPaint.dll, so Thunderstore/R2ModMan installs show Sprays under the installed plugin folder instead of the global plugin root.
• Old images in the global BepInEx/plugins/SprayPaint/Sprays folder are migrated automatically.
• Images placed directly beside the DLL are migrated into the new Sprays folder.
• Documentation updated with the new paths.

0.1.2

• Documentation only: clarify the Sprays and Sprays/Received folders and move the image-folder instructions to the top of the README.
• No gameplay changes.

0.1.1

• Added host-controlled multiplayer file transfer permission.
• Added independent received-image dimension limit.
• Added received spray size override.
• Received images are now stored only in Sprays/Received.
• Added menu X/Y position rows with screen clamping.
• Added preset delete confirmation with Backspace.
• Fixed ARGB/RGBA texture cache channel swap that caused reddish or oversaturated images.
• Fixed cache-hit logging when the target file already exists.
• Updated Thunderstore README and package metadata.

• Content hash cache and persistent hash index.
• Host-controlled file transfer permission.
