Nows a good time prior to Sahcon to build yourself a homestuck troll in vroid studio.

(and i personally use it from steam)

You can export these models directly into vrchat and blender, there are good tutorials if you want to make modifications to your model in blender, but exporting as an .xavatar and importing with the xwear manager sets up almost everything for you (this is what i'm personally doing for my troll!)

heres a tutorial if you'd rather take the blender route:

https://www.youtube.com/watch?v=Qbwl9XIONuQ (older, has more advanced things)
https://www.youtube.com/watch?v=HPXe0a_yMQc (seems recent, skimmed through it)
A lot of people model out their horns with the hair editor (3d splines!), Icetal's horns are modelled out in blender (also with 3d splines).
heres a horn tutorial for blender I really liked:

I can't help with texturing (you'll need to learn about model seams!), to export it into xwear accessory, i had to pull it into unity, I followed this tutorial from pixiv to import it, not a particularly painful process.

heres a link of assets I've made, including raw krita files (a lot of them are vector files, so you might need to export them manually from krita if you want to use another program!) which will hopefully help you get started:

I'll probably be blogging updates regarding vroid modeling my own OCs, I'll also try and be available to help anyone who wants to make a model!
