This is all content that has been successfully ported from all expansions up to Shadowlands to work with WotLK. Technically, it's ALL m2s/wmos and their linked textures exported from retail 9.2.5 using the WoW Export tool. Then all files were TXID fixed, along with being ran in the MultiConverter. Afterwards, a python tool I made was used to remove all files overlapping from vanilla WotLK content. This ensures that ONLY expansion content is in this file. I am absolutely confident this is currently the best patch available for this kind of content.
Enjoy M2s, WMOs, tilesets, textures, flames, and other visuals from Shadowlands, BFA, Legion, WoD, MoP, and Cata.
The files are available in BOTH an MPQ and loose file format. The MPQ version is a 15.3GB download, labelled Patch-N.MPQ. The loose files are in a highly compressed 12.2GB .rar file. When either of these are exported, there should be 179,530 files totaling 28.8GB. If you'd like to use it in noggit or your client regardless of the content, download the MPQ version and place it in your Data folder. If you want to only use the tilesets or specific expansion content, download the loose file version and create your own patches with MPQ Editor.
THANK YOU FOR THE FOLLOWING RESOURCES, WITHOUT THEM BEING AVAILABLE, THIS PATCH WOULD NOT EXIST -
Alastor's Expansion patch, commissioned and distributed by Valaryon
Adspartan's MultiConverter, adjusted by MaxtorCoder
MPQ Editor (3.2)
Implave's 8.1.5 - 10.1.7 WMOs downconverted to WotLK 1.0.0
Implave's Fixed 8.2-10.1 Tilesets 1.0.0
Known issues -
A lot of Shadowlands WMOs don't work. I ran this in TXID fixer, then Multiconverter, so I couldn't say why they don't. They just don't.
Lava/Slime is broken. You might want to delete them before making your patches.
No DBC files are in the .rar. These can only be spawned in noggit and not in-game.
My meme name for the folder is still in there, dubbed "supergoodportedstuffnotedited". Woops.
Notes -
If I find the time to separate these patches out, I'll return with a patch to update this link. If given the same circumstances, I'll also provide a DBC file to merge with yours along with instructions to spawn them in-game. Keep an eye out for updates here if they happen 
If used, credits are appreciated! This took about 3 days to complete along with 200GB of drive real estate to mess with these files and make sure a working product was achieved. That does not include the cooperation of community members who contributed to this resource - those individuals should be thanked and appreciated for their contributions to make this happen!
Also, check out Ember, where this content will be used in a roleplay setting!
Thank you for your time and reading this. This is my first submission to model-changing.net and I hope it's useful to someone.
