hi
i am new at the unity forum, and i was wondering if there is a artist corner at this froum?
thx in advance 
Not in particular, but coders and artists get along just fine here 
Might also be worth checking out http://theunityartist.com if you really want a more artist centric forum.
Artist forum could be considered the Showcase as that’s where everyone shows off their work. General questions about art and the art pipeline in Unity generally stay in Gossip and might fall under shaderlab or Unity Support depending.
Nice question btw. Because I also see huge artistic and creative potential in Unity3d, which could be used not only for game or scientific projects, but also for virtual installations. Just my 2 cents
