Roughly speaking everything will work in Poser 3 except:-

• Any P4, Michael or Victoria figure/clothing unless you have purchased those items separately.
• Conforming clothing (The work around is to pose the figure and copy the pose to the clothing)
• Transparencies. Poser 3 does not support transparency.
• Some texture maps ... you may need to convert to TIF format

I know there is more but those are the main differences. If you are downloading freebies you have nothing to loose by trying. You may get a "Newer Version" error... just click the button labeled "yeah ok I got the hint, I'll upgrade one day" and continue loading.

I still have my old site on line which is totally Poser 3 and all free, help yourself. Just bear in mind that they are my early works.
