That’s the point, there are some things i’ve seen, but they aren’t promoted much. It requires a place which is linked to the THREE Hotspots like here and the website or people won’t find it.
For example a agency needs to develop a product presentation, they’ll look for the right toolset and also a toolset which offers as much as ready-to-use as possible. It only gets really saturated by a marketplace developers actually can earn money for their work. If you require anything at Unity, Unreal, GameMaker, Construct etc. there is a well categorized store with pretty pictures you find mostly anything needed.
The fact THREE is a rendering engine makes it a even more attractive market in my opinion, since it’s not tied to a more specific engine structure even different engine concepts can be offered for games and apps.
You can basically put more effort in paid modules, on how extensive and fast it will be done as well as support and maintenance. I don’t want to say open-source isn’t good or good enough, but you know what i mean i guess. Other shops, for example, also offer extensive tutorials and similar. It clearly separates from free work, since you need to offer support and maintance for your products, that’s what a lot companies missing in THREE related work, not THREE itself, since the community is great with Github and the Forum, but the smaller individual modules often lack support, they often end as dead outdated code without any maintainer. You can simply put more serious effort in paid work if you don’t have much freetime.
I was actually looking for such a marketplace and don’t really have the time to start one, at least not alone, and only if it’s related and linked to THREE officially such a marketplace would be relevant.
I don’t imagine shop items jumping in your eyes on the official page, i only mean linked just like the forum, github, docs etc. is on the left side panel, so people interested in THREE will also see there is a store, and very often those will browse such as well as the promoted examples. (like the example with agencies)
But that’s just what counts, it can only happen if the community wants it.
Edit: Since you changed it
I didn’t said to make THREE any kind of commercial as Unity, it’s about a marketplace for developers. UE and other engines are free too, but also offer a marketplace. This also doesn’t mean everything to be premium, at the moment there isn’t even a categorized portal to collect and promote THREE related libraries. You have to dig through the Forum, randomly stumble over on Stackoverflow or find and pick things together with search engines.
I don’t see why there would be a dislike for such a platform, any argumentation?
