There is another thread just opened about this, but since I started it here, I'll continue. I have read the older posts and what other people did to get rid of it. This is what I have done so far: Yes, in wireframe you don't see any object serving as base for the plane to be there ( I went in very detail on this just in case). Then I went to CM and found the jet effect item. You would say that if you screw the Config file the asset will not show. I deleted it jointly with all the other files. Jet effect can't be deleted because is grayed, but now the file is empty and I also deleted the contents from the recycle bin. So in fact, this asset should not work. But the plane still flies! A "Find asset" shows that the asset is not there. Then I must assume that this particular asset is called something different, but since I can't click on it, it does not show a KUID in surveyor. Does anybody has any more ideas? And yes, all the other comments you may read in the other thread, applies to what I see, so is the same.
