AutoCAD Architecture :: Rendering Color / Lighting Output

I am using arch 2009, I have a bizarre issue with the rendering output soley based it seems on what version of Autocad the original drawing was created.

I have a block with 3d elements & materials, I insert it on any drawing which was created in release 14 which just about 100% of our drawings are (because you know, you take your old title blocks, convert then to the new version of Autocad, year after year after year, so the original title block was created way back when, just saved in the new format.) Anyhows, these are where the 3d blocks were created, newly in r2009, on on drawings originally created a long time ago. We just created new office title blocks from scratch in r2009 starting with the acad.dwt template.

When you insert any of these blocks, render it, the colors are different, too bright. here are all the specs for both drawings, one with the corect colors, one without. We have a ton of these blocks created over the last year or so which we render in Acad for the graphics guy to use for color elevations so its a pretty big deal if the color output is not reliable, it should be the same if all your settings are the same regardless of where the drawing file came from. I have missed something, and its probably something simple, it always is.

1. Same block with same material specs, verified on both drawings.

2. Zero lights, as per the lightlist on both drawings.

3. LINEARBRIGHTNESS - set to zero on both drawings.

4. LINEARCONTRAST- set to zero on both drawings.

5. DEFAULTLIGHTING - set to ONE on both drawings, viewport.

6. DEFAULTLIGHTINGTYPE - set to ONE on both drawings, viewport.

7. Render envirionment & render settting dialogue boxes, match line for line, verified.

Here are the 2 rendered images of the same block inserted on 2 different drawings. The darker one is the correct one:
