ok sorry I am not so expert in this forum, but in other websites exist categories named as "3D comics" because well its a 3D comic in fact.Anyway thanks for the clarification.
Here "comic" has pretty strict definition which includes three main points: it must be pornographic in nature; it must be of Western origin; and finally - it must tell a story using a flow of panels, with more than one panel per page. >>https://ehwiki.org/wiki/comic
Per se, there may be a 3D comic by all thouse parameters - HOWEVER: all 3D work must go to "Misc" category by the rules of the site, and tag "comic" must NOT be used outside of "Western" category; which makes usage of that tag on any 3D gallery impossible due to rule conflict.
Link to Wiki is in the right corner, between "Forums" and "HentaiVerse", by the by. Speaking of forums - they are open for everyone, don't shy of asking questions there - technically speaking, this comment falls under the "bad comments" guidelines, but c'est la vie
