There’s a lack of centralized information on WorldBuilder. Relic has given us little to work with and most of what we know is from community members working with trial and error. In the interest of helping new mapmakers I’ve compiled what’s available into an organized list and posted it on the new gamereplays.org modding forum so I can keep it visible and updated. Feel free to post your questions and works in progress there; the GR forums tend to house some very competent players and some of them might offer to playtest your work!
