reduced visible distance for casino indoor props, but took out some props to draw further to reduce popping
raised interior culling volume because we should not see the interior furniture at street level (+1k batches otherwise)
added a regular props_culled culling group for props on the outside to cull like other barges
re-organised prefab categories to be in line with other barges hierarchies
added some polygon surfaces inside the casino floors to help with automatic culling of objects below
