The best plan would be to do what Ziro said at the end and come up with a system that hides everyone except yourself and use client-side script for the cut-scene.
copylevel usage:
copylevel works off the levels folder as it's base so it can be a little confusing, in this example the template level is stored in:
levels/baselevel/housetemplate.nw
and it will be copied to:
levels/houselevels/house_account.nw
PHP Code:
function onCreated() {
copylevel("baselevel/housetemplate.nw", "houselevels/house_account.nw");
}
Make sure your folder config includes:
level houselevels/*.nw
Otherwise you won't be able to access the level.
