Just an update, I've got it to work. For my case, after a few testing, it appears that it will only show properly if my textures are 2056x2056 size. Anything less and it doesn't show.
Now here is my new problem. I created a very large floor. I used the exact same settings, but the new large floor doesn't work. When I try to place it in FPSCR, I don't see the red glowing circle that symbolizes an entity, all I get is a tiny dot that changes from varies from white to red color. What could be wrong with this one?
