I hope garagegames include some information here... Since it's been viewed over 2.000 times and still nothing, it would be REALLY nice if they did so.

The person who accessed this the 2,766th time says: "I concur."

3206, mmmm and still nothing.

Nice to see that even if they say there's plenty of documentation for this engine, I still find difficult to add simply things like gravity and weight to a sphere...
