SDK exclusion rectangle

Hi guys, I was trying unsuccesfully to understand eclusion rectangles usage…Simply i dont understand the thing in which i have to delete the content.xml of my scenery to get things work.
If I open the developer mode and place an exclusion rectangle, it will work during developer mode, but as soon as i place my package in community and fly normally it doesn’t work anymore

What can i do ?

Exclusionrectangle works when the content you want to exclude is loaded, in the virtual file system, before yours.
This is done via package name in alphabetically order

Have a tutorial about that, it is slightly outdated (because now the content.xml can be overriden using the re order packages tool)

To my knowledge, the content.xml is currently ignored completely.
