Hi! I've seen indie studios go far off of game jams before, very exciting! My name is Uno and I'm the admin of the Northhack Nexus. We're a game publisher that also organizes groups to join game jams, and we'll be putting teams together for this upcoming Brackey's Jam. I don't know if you've already found someone, but we have some 3D artists in our community. Furthermore, we can provide some guidance during the jam with our tools and our experience, and assist you beyond that if the project seems promising. We're currently managing several dev teams on a similar scale. We'd love to have you!
