Fleasion v2.0.0

VERSION 2.0.0 UPDATE

Fleasion has switched domains

Fleasion has now left Beta, as such this is the final release that will be posted on this account. For all future Fleasion releated releases/news check https://github.com/fleasion/Fleasion

This update is mainly focused on adding more utilities and adding more support for animation and TexturePack assets.

More animation support

• Conversion to curve animation: Added support for converting any animation format and exporting as curve animations.
• R6<->R15 Manual and auto conversion: Added support for manually converting animations from R6 to R15 and vice versa, also auto converts and detects rigs live when replacing all animations (does not support converting let's say a r15 animation to a non-player animation like a reload).
• R6, R15 and Non-player animation asset type support: Added R6, R15 and Non-player animations as asset types in asset filter, this works by scanning the response of the fts.rbxcdn.com request for specific instance names like "Left Arm". _{Note: Some R6/R15 animations will be detected as Non-player animations since it works by detecting Non-player rig instance names like "Mag", "Gun", etc. if you want to replace those, just make separate profiles for the specific animation or replace all Non-player animations (this will break some animations).}

---

UI/UX related stuff

• Improved the flow of using preJsons: Gave preJsons a UI that automatically fetches games from the preJsons repo and displays them in a grid with the game's name, last updated time, created time and thumbnail.
• Added more tabs for various utilities: New tabs like, miscellaneous and Subplace Joiner. The miscellaneous just has random utilities that would be useful for the average player, more utilities will be added in the future as Fleasion aims to be a general use program that includes utilities for everything, not just cache editing and scraping :P
• Option to choose which columns to search by in the scraper: Added an option to select which columns the search should affect in the scraper.
• Sorting columns in replacer by clicking column headers: Added support for clicking the headers in the replacer to sort just like in the scraper.
• Added awesome time wasted stat in logs🔌 (trust this is very necessary).
• More options when you right click in scraper: Added more export options, option to send selected to "Replace with" and also "Export as game dump". This export can used in the new preJsons UI to easily add your own games to preJsons.
• Settings tab: Added a new tab all the way to the left that has all the settings that can be found in the system tray QMenu.
• Blacklist IDs: Added an option in the scraper to blacklist specific IDs from appearing in the scraper.
• Clear Cache button: Added the Clear Cache button to every tab in the bottom right for easier access.
• Added option Enable/Disable configs from the system tray.
• Added "…" to the end of buttons that open a dialog that were missing it.
• Moved some settings to the settings tab/sys tray.
• Added a warning for if no Roblox installations are detected upon launch.
• Added a search bar to the logs window aswell as "Copy All" button.
• Various small improvements to the UI.

---

Utilities

• Account manager: Added an account manager in the miscellaneous tab that you can pair with multi instance launching which is also in the same tab.
• Reserved server rejoiner: Lets you rejoin your last joined reserved server (servers that others can't join, basically a private server but at the same time not a private server). _{Note: This only works for 5 minutes after joining the reserved server.}
• Subplace Joiner: Lets you join subplaces and specific jobIds. _{Note: Some subplaces won't work due to a recent Roblox patch or restricted access settings.}

---

Improved support for TexturePack replacement

• ORM channel compositing: TexturePack slots can now be replace on a per-channel basis (Metalness, Roughness, Emissive, Height) using individual PNG files.
• Blank KTX2 slot removal: Removing a TexutrePack slot now serves a 1x1 blank texture instead of breaking the entire pack.
• High-quality KTX2 storage: CacheScraper now stores KTX2 files for TexturePack slots with fidelity tracking and channel mapping.

---

Bug fixes

• Fixed Fleasion crashing upon config creation with invalid name.
• Registry PlayerPath now strips null characters.
• Cache deletion preserves essential directories.
• Rich text formatting disabled in cache viewer.
• NumPy added to PyInstaller hidden imports for proper bundling.
• Fixed Fleasion breaking if open while Roblox updates.
• Fixed fetching the incorrect IP for assetdelivery, fts and gamejoin when using WARP or VPN.
• Force UTF-8 encoding to file reading for various things.
• Changed error that appears when you try to preview Roblox original font to be more understandable.
• Fixed preview not updating when trying to preview original font while using a custom font.
• Fixed 0-face LODs being loaded when previewing specific assets.

🎬 NEW: Modifications Tab — Full Local File Replacement System

Replace ANY local Roblox file with your own custom versions — forever persistent across client updates.

Core Features:

• Fishstrap-Style Mods: Replace local Roblox client files (textures, meshes, sounds, fonts) with custom versions that automatically persist.
• Originals Auto-Stashed: Modified files' originals are automatically backed up and can be restored at any time without losing your changes.
• Flexible Source Options: Apply modifications from:
  • Local file paths (browse or paste)
  • Roblox Asset IDs
  • URLs (HTTP/HTTPS)
  • Type "remove" to delete a modification entirely
• Smart Multi-Account Support: Auto-detects all Roblox installations across all user accounts and applies modifications uniformly.

Pre-Built Modification Categories:

• Textures: UI, GUI, and environment textures
• R6 Default Avatar Meshes: Replace head, torso, arm, hand, leg, foot meshes
• Avatar Head Variants: Add multiple custom head options (with dedicated "Add Head Variant" button)

• Place Asset File Type Fix: Corrected the exported file type for "Place" type assets from .rbxmx to .rbxl / .rbxlx.
• TexturePack Export Improvements: You can now export TexturePacks as XML manifests or extract individual texture images. Improved TexturePack slot identification for per-map replacements.

---

⚙️ TexturePack Slot-Based Replacements

• Per-Slot Texture Replacement: You can now target specific texture maps within a TexturePack (e.g., just the normal map) using slot keys like assetId:mapIndex instead of having to replace the entire pack.
• Sub-Asset Auto-Resolution: Sub-asset IDs are automatically mapped to their parent TexturePack and slot position, allowing seamless per-slot targeting.
• KTX2 Automatic Conversion for TexturePacks: Non-KTX2 image replacements for TexturePack slots are automatically converted to KTX2 format on-the-fly.

---

⚙️ Performance & Under the Hood

• Faster Process Polling: Decreased the interval between Roblox process checks from 1 second to 0.5 seconds for more responsive detection.
• SolidModel Detection Improvements: Improved CSGMDL detection to correctly identify actual 3D models and avoid incorrectly treating non-CSGMDL .bin files as meshes.
• Raw Asset Sidecar Storage: TexturePack KTX2 files are now stored as raw sidecars for direct export without re-processing.

---

Fleasion v1.4.2

BETA TEST 3 | VERSION 1.4.2 UPDATE

Cache Viewer & Previews

• Audio Overhaul: Rewrote the audio player with proper pause/resume support and a redesigned UI (buttons moved to elapsed time row).
• 3D & Animations: Added XYZ axis indicators to the 3D viewer and added placeholder support for non-R15/R6 animations.
• Exporting: Added new export formats (Converted, Binary, Raw) and a "Copy Converted" context menu option.
• Bug Fixes: Fixed preview issues for images, texturepacks, meshes, and solidmodels. Fixed animation previewer path resolution for frozen exe (PyInstaller). Fixed preview pane issues after database deletion and improved general viewer performance.

Dashboard & New Replacement Engines

• Rebranded "Replacer Config" to Dashboard with a fully reorganized UI layout.
• Hybrid Replacement Logic: We have expanded beyond basic ID-swapping to offer three distinct modes:

ID Replacement: No files needed on your PC, very user-friendly. (Subject to Roblox moderation/privacy).
Local File Mode: Uses local files to resolve hashes from request headers. This allows you to load anything (like an .ogg for an .mp3) without moderation or conversion issues, but requires the file to be stored on your PC.
CDN Mode: The "Best of Both Worlds." Load files directly from services like GitHub. It carries the benefits of local loading (no moderation, no file-type restrictions) without requiring users to manually manage files on their own machines.

• UX Fixes: Changed editing dropdown to button+menu style, added auto-refreshing for config dropdowns, and fixed tray menu ordering.

Search

• Performance: Rewrote search logic for cache and JSON viewers to prevent UI freezing during large queries.
• Stability: Added 1-character minimum search buffer to prevent crashes on single-character input.
• UX: Simplified search implementation and added JSON Enter cycling.

Proxy & Scraper

• Performance: Major proxy optimizations to fix ping spikes and bandwidth throttling.
• Scraper: Fixed toggle not reflecting actual state when GUI is reopened.
• Fixes: Fixed texturepack interception and removed unsupported mitmproxy options.
• Added more logging to scraper

Settings & UI

• New Toggles: Added "Always on Top", "Auto Delete Cache on Roblox Exit", and "Open Dashboard on Launch".
• Fixed dark mode text.
• Launch Options: Added "Clear Cache on Launch" (terminates Roblox and deletes cache on proxy start).
• Visuals: Improved welcome message/setup flow and widened About window to 370px.
• Logs: Added timestamps to all log entries.
• Defaults: Changed strip_textures default to False.

Project Status

• FULLY OPEN SOURCE: To address concerns regarding the safety of the tool, Fleasion is now fully open source. You can audit the code yourself here: https://github.com/qrhrqiohj/Fleasion
• Cleanup: Streamlined project structure and removed unused files/documentation.
• Legal: Added MIT license and comprehensive README with full Scraper documentation.
• Credits: Updated credits to @8ar__, @BLOCKCE, @1_v, and @0100152000022000.
