First I enable the resourse I want to use. Then I add what content I need to add into my mod. I save. But when I load the mod in the manager, and boot up the game and the none of the downloaded content is there. If resourse was armor or clothes then who ever is ment to wear them is naked, any static objects are gone. Even when I start up the CS again the stuff is gone. Basicly put, anything that is not vanilla has vanished. I am not using vista and i have made sure that the plugins are in the correct order. If anyone has any ideas it would be very helpfull.

Are you doing this by activating two .esps at once (yours and the resource)? Oblivion's CS doesn't allow .esps to be dependent on each other.

You might have to merge them with Tes4Gecko instead.

Another method is finding the mesh/texture folders in the resource and then making your own folders for the files you want such as Meshes\Armor\MyMod\Cuirass and Textures\Armor\MyMod\Cuirass

then, drop the files you want in those folders. Of course, you'll have to make a new item in the CS pointing it to those new locations, but it'll work that way.

Edit: If you choose that method, don't forget to credit the original author of the resources! Well, you should credit them anyway... but don't forget!
