My first exposure to jME was somewhere around 2006 when I was playing with some terrain rendering and generation. I was also exploring alternatives to an in-house Java wrapper around Open Scene Graph that we’d been using since 2002 or so. Years later I returned to revive that terrain project in a different non-photo realistic form that became Mythruna. jME3 helped that project get off the ground in a matter of weeks and the community has been very welcoming. The flexibility, support, and momentum made jME3 an easy choice and it was impossible not to feel like getting involved. I have a lot of background in open source software and have several of my own projects out in the wild but the jME team has been easily the most welcoming that I’ve worked with on a project this scale.
