I struck out on two items of the check list. I don't have any side rail models that fit this table. The area for side panels is quite short so there is very little room for anything anyway. The only thing that might fit there is a star field but I've decided to not add side rails. The other item I can't do are the bump maps. The texture for the space shuttle is too smooth and so there are no bumps that show up on it after going through the process. I tried adding bump maps on some of the plastics but those use TGA files that are mapped for areas that are transparent. I determined that bump maps don't work on TGA files. The plastics are supposed to be flat anyway.
Let's proceed on to the good news. I have successfully added shadow maps. They don't always work on every table but they do on this one (at least on the front of it). The back of the playfield has large black areas where the shadows don't work as well but they look good on the front which has wide blue areas.
The way I add shadow maps to the slingshots is a little tricky. This table like many others I have worked on only has 4 bulbs that light up that light up brightly when the slingshot is hit. Unfortunately, I can't get the shadows to look right when the slingshot is not being hit. So I add 4 more bulbs that are always on. Then I add shadow maps to all 8 bulbs. I would like to stack the 4 always on bulbs directly on top of the other bulbs but the shadow maps don't work this way so I stack them partially so they are slightly offset. Anyway they are close enough so that a 2 bulb set cast the same shadow. Doing the shadows this way makes them look good when the slings are not being hit and the bulbs cast a brighter shadow when being hit.
I usually add the lighting before the shadow maps. I have found that I usually have to rework the lighting a bit after I add the shadow maps. We'll see how it works doing the shadow maps first on this table. Anyway the following is a screenshot of how the table looks now. The back part of the table looks too dark to me but that will be fixed when I do the lighting.
