Renders depend on a light-material-render engine relationship triangle these were all changed from P8 to PP2012. I would be surprised if anything rendered well from P8 to PP2012

1 delete all the lights from your P8 scene

2 remove all the advanced modes in the texture room reset to simple

3 Save As

4 Open in PP2012

5 Light with IDL dome, spots,and points

6 Texture using SnarlyGribbly's EZSkin and Scene Fixer

A word is not the same with one writer as with another. One tears it from his guts. The other pulls it out of his overcoat pocket
Charles Péguy

 Heat and animosity, contest and conflict, may sharpen the wits, although they rarely do;they never strengthen the understanding, clear the perspicacity, guide the judgment, or improve the heart
Walter Savage Landor

So is that TTFN or TANSTAAFL?
