Cleaning up the red box was quite tricky, and not as easy as I had anticipated it to be. I thought that I would use a 3d card and clean it up, but the problem was that the table would overlap the box.
To fix this issue, I had to 3D project it first and then clean the red box and then add the table on top of the 3D card.
The vent was transparent and I had to place a card to make sure that the vent had an off-black background.
We had to add the university logo to the frame. I used Photoshop to make the logo and added some paint and spots on it. I used new cars to project it on the wall. This had the problem of the over-scanning and I changed it on scanline render. The white and black helped the alpha.
