Hey rookief.

I don't know much about how Random Talking Bush and others do their fbx exports. You're gonna have to ask them instead. Sorry.

But if I had to take a guess as to why your fbx exports don't work, it's because if you open your shader editor and check one of the materials, you'll see a really complex web of nodes (see the attached picture). This is just how the python script sets them up in Blender, I guess.
An fbx can have embedded textures, but it can't really just take a complex material like this from Blender and just send it over to ZBrush. ZBrush wouldn't know what to do with it, since different softwares have their own ways of handling materials differently.

So why does the Sprigatito fbx you downloaded from this site can be imported to both Blender and ZBrush? Well if you check its materials (see the attached picture), you'll see that the complex web has been reduced down to simple shaders with some textures. When a material is this simple, they're easy to import to just about any software.
