So it generates hair, but not properly on the mesh, here is a gif: 02acaa188e4642b833fec3209f0fdfca

Would greatly appreciate the assistance!

I don't see anything unexpected in the GIF you posted. What do you expect to happen instead? My guess would be that you want the hair particles to follow the surface of the mesh more closely. For that, I think you'll need to make some adjustments to the particle system's setting. Particularly the "Children" section.

I have tried every setting, when I get it following the mesh closely, there's a lot of gaps and that shows in the render. What I want is it to directly follow the mesh? I mean it's making the tips really fat and they're not like that AT ALL. I really love this addon I just really need this to generate properly!

I could be wrong, but what I see is that you've got guide hairs laid-down on the mesh you made (I can't see them in your GIF, but they seem to be following your geometry closely) and the child hairs are being generated, by Blender, surrounding them within a set radius. It sounds like the child hairs stray too far from the mesh, making the hair take up m ore volume than you want. That's not something HairNet can fix, because it's an issue of how Blender adds child hairs around guide hairs.

You could try shrinking your mesh, so that when child hairs add volume to your hair system, they appear in the right place, but I suspect that wouldn't work at the ends, where it's so much narrower.

It might work better to increase the "Subdivide U" setting when you generate hair. That would give you more guide hairs, so that the child hair radius could be smaller.

I'm sorry I can't offer more than workarounds, but this is a matter of how Blender implements hair and I can't address it through HairNet at this point.

If I'm missing the point, please let me know.

I think you've understood what I was trying to say but I think you'd see closer what the issue with adjusting the children settings is if I shared the hair strand mesh so you could try it for yourself. I have supplied it in this post. Also is there any other way I can contact you? More conveniently than GitHub? Discord perhaps?

It's just a simple scene with the scalp and a hair piece

I looked at your scene and I don't see anything out of place. HairNet seems to be doing what it's supposed to. I guess I don't understand what you expect to be different. Is it the width of the hair strands?

Good morning guys. I was going through the discussion and it sounds like you're expecting to get really good hair coverage but you're not seeing that represented in your renders. That wouldn't be an issue with HairNet but rather with the hair / children root and tip settings. Nazar has a great tutorial around this and it may be exactly what you're looking for. Don't forget that the scale of your model also plays a part (no pun intended) in the size of the hair root and children to get the desired "thickness." Hope this answers your question! :)
