Since i did learnded somethings from the getting started docs and the other, i never knew how to remove the invisible "wall" that in TAT you can go farther than where it is, does anyone knows about this ??

I used search but couldnt find much...

Delete the invisible collision objects.

If you mean that there are any objects in the layers just where the walls are... there are no invisible objects there.

Well, i did deleted i remembered but they still are in there...i wipped the whole layer...
