Would anyone really have a problem if there was one gallery and not separate ones based on software?
Not at all. I often miss good stuff from other DCC packages with V-Ray.
+100 here ,I would love to see that happening too ! maybe with a thumbnail for each project, fixing vimeo links, support on social media Chaosgroup account .or any other addition that will make people more interested in sharing their work here .
I’m sure I will learn too from other DCCs about possible techniques that I’m not aware of , or at least we can see a feature in that VRay implementation that we don’t have and start nagging about it =D
I requested a joined forum for all users so we can talk about render theory and share pictures etc a while ago, not separated by Software.
It shouldn’t be a hassle to open another sub forum.
I have some things I like to talk about with all users, so, please, @vlado get someone to do it. Thanks 
fantastic idea.
