Sorry guys, I didn't mean to open a war of fighting words.............
I had uninstalled P7 and deleted all folders 3 days ago, done because the libraries were a mess with a lot of items in wrong places etc. Poser 8 was supposed to be my fresh new start.
I re-installed Poser 7 today to make use of its folders for lesser used items but seems some random things such as poses and cameras from P7 just wont work, you can apply them in P8 but "no go ". That problem is still my main question.
My original content hoarded over the last few years is stored mostly on CD's, DVD's and recently a 1TB external drive and you guessed it, many older zips and files do not have PNG's.
I have P3do pro and yes it does convert the rsr's. It can also view the contents of zips and install them into Poser's runtime. I'm testing that facility at the moment, so far so good.
Tommy.
