The kicker bevel will add a lot of realism where it is needed a lot.
I hope, as you have probably gathered, for control of ring assembly material on the pop bumpers. and a pivot for the flippers would be good. I still personally think a material that does absolutely nothing, and contributes in no way to any effect is a prerequisite to my being able to work with it. I have always looked at it as an art form. If there is a reflection, a glow, a shadow, for some reason a fog, etc. I would like to be able to create it myself. A program that does that stuff would be great, but it would have to do it damn well.
Full modulation of lights again, If I don't put a light above the top right corner of the table, or in the middle of the apron, I don't want to see light there. If I add a light, it's to light the nearby objects. VP lights look to me like they only light up non existing particles in the space between the bulb and near by objects. Earlier betas seem to me to be superior in that respect.
I still think it is good enough as it is, to be the best in most respects though. I still don't think I could do much with it myself, but it is capable, in the right hands, to grind out a rather nice pinball simulation.
The wire triggers are like the pop bumpers. The entire piece was modeled, but when installed they should seat into the table not just dropped on to it. It would be like a fantasy table with a tree. If a tree was a VP element and added to a table all indications are that the bottom depth of the roots is what would be sitting on the table surface.
