I was thinking of a way to get people to interact with the community..
What about a weekend "modelling mashup"
we give a topic which will be something with a number of parts/componenets.. like an Suit of Armor or a Robot.. entrants volunteer to do a part.. or more than one part. The contest organiser then mashes them all together into one model..
(maybe it can be automated?)
eg: in the Suit of Armor mashup..
someone does the helmet in the style of a shogun mask,
someone else does the vambraces(arm parts) in a scifi style..
someone does the legs in a Orc armor style..
someone does the torso in a dragon scales style..
the result will be a badass amalgamation of all our models
Another idea would be to have us work on various themes like Island theme, war theme.. to create assets.. that will then be put in a free Sketchfab Asset pack that the community can download. They could even be in some modular format.. like minecraft.. or the image below
and then in the following week we have a contest where everyone who wants to enter, comes up with a composition using the same building blocks(modelling skills not required).
