Re: 3dmax rich frames and material ID

you should read up on the texture map replace operator in conjunction with RPF files. one issue that has come up in the past is a slight aliasing at the edges, vbut in the case of a flat tv screen you could have an overlay pass of a slight besel/frame on the TV that hides any artifacts, if present.

top layer = frame with hole in it
bottom layer = RPF with texture swapped out.

if you make the original texture a flat black and then use additive to do the replace, it will be the full, new image replacing black. you should also be able to give a slight specularity to the screen and have it remain.
