>>2634215The only thing the prefab is, is the fbx with a viewball attached to it, and set up with Humanoid rigging. It takes ten seconds to set back up. It takes literally no skill whatsoever...although it might stop YOU because you don't understand the first thing about avatar creation, I find it hard to believe it would deter anyone but the newest newbie.
The package might also include the shader and some animation files, which might stop very few users from using the model as an avatar, but are also easily recreated (a quick search of the booth page will tell you the shader used, and you can always just reshade with your preferred shader in seconds). In fact, most VRC users who would be interested in making avatars likely make their own shader tweaks and animations, as they're pretty easy to learn. They're the first thing you learn when you learn to start personalizing avatars, along with texture edits.
Even stripping it down further than that, even if only the pmx is included, and not the fbx at all, there is a plugin for Blender that allows for pmx-to-fbx setup specifically for VRC that has you smack like...seven buttons...and you're set. pmx-to-fbx conversion is much, much easier than fbx-to-pmx, as it strips the physics and simplifies the bone structure.
I'm not sitting here saying you should share the unitypackage if you don't want to, share whatever the fuck you want, but you shouldn't give advice based on something you obviously know nothing about.
And to sum everything up, Maya is currently one of the most popular new avatars from the last month, and it "leaked" a week and a half ago. Everyone who wants to use it already has it, and the only reason it hasn't been posted here already is because you're all fucking jerks who beg for everything and share next to nothing. (With apologies to behemo, gr33n, J&J, anonripper, that guy who converts Jean models into English, and anyone else I might be forgetting, which are the only reason I still come here.)
