since you love reverse engineering a lot from your blog posts it seems, if it isn't too much to ask, can you look into this .unr file which is basically an unreal map that was made with an internal tool at Ubi HQ for a 15 yr old game (splinter cell conviction) . It won't load inside UEExplorer or any of the openly available UE tools. Perhaps it could be a topic of your next post in addition to being tremendous help for the gaming community as only basic mods can be made for this game currently unless someone can figure out how to load its maps somehow
