I'm not sure if this post will get much traction with the forums being basically dead. But is there anywhere to find modern retro-porting tools to retroport models from current expansions to WotLK?

I think it really depends on the kind of work you want to do.
Most .m2 models are retroportable using a combination of a customized fork of the multiconverter, m2mod and wow blender studio.
here is the copy of the multiconverter

m2mod can be found here

Here is a link to an old forumpost with some explanation on the two previous softwares.

 

And wow blender studio can be found on the wow blender studio discord.

 

Other very important tools are Amaroth's templates for 010 Editor, especially those for the .m2 files (sometimes the new models will mix up the flying and swimming animations as in WotLK they were one and the same ans also have the Z source of the particles flippe, so they have to be changed by hand)

If you are planning on working on .WMO models, things become much more ocmplicated as in mid Dragonflight Blizzard decided to change how materials were coded into the models and sometimes importing them in Blender will scramble the textures AND change the collision into an untextured polygonal model, so for those there is a whole lot of extra work to do and it's beyond my current abilities.
