Hey!
Right, I’ve been working with my project for a while and everything was going smooth untill I made 3 planes, 2x for showing 2x images and 1x for being the floor of the whole world. and then I hid the camera at the end of the movie inside of a box. then I saved, and now whenever I render I only see this plane floor and that’s it. I had a whole city in the middle on a tiny island and I can see it if I put on textures in view mode, but when I render it I only see the floor plane which goes quite far below the city. 
what is causing this problem? Do I need to upload the .blend file or not? that’s the question… well say if you need more information!
Thanks in advance!
