Poser cannot render both cameras in one
pass so he will have to render the
second "six inches to the right " version by itself correct?

@Bagginsbill just like you have to see a persons node setup before you can definitively tell why his material has no "specular"

until we see a screen shot of his GRAPH EDITOR of the problem scene file every suggestion we are all offering must be considered sheer speculation.

My GUESS is There is no need for a second "parented" dolly  camera to be "in lock step" with first
in fact I dont find where he states such in his post

this can be achieved with ONE camera

"For the second rendering, I just dolly the camera a little to the right and I'm all set.

My new project had zooming, rotating etc. etc. of the main camera. When I go to the first frame for the second rendering and dolly the camera, it only works for the first frame."

My GUESS is What is happening he is moving his former stationary camera on frame one this is autimaticly setting a key frame for that frame only in the" six inches to the right" position'

he probably has his interpolation method set to linear.

that one new position frame is not going to hold his camera "slightly to the right" for his entire sequence he needs to set at least on addition keyframe at the END of the sequence "holding" that "slightly to the right position.

anyway its friday  Got to run to the Mosque
OP: please post a screen shot of your  graph  editor for a proper diagnosis
