Thanks Ged, I did install this one some time ago but my C drive was SSD 120 GB and almost full (now SSD 256 GB) and I ordered another 16 GB RAM (will be 32 GB). It should run smoothly.
The first time I opened it was quite a shock, but hey, I have time enough.
Thank you guys for your feedback...it's much appreciated.
More or less I followed this tutorial. http://photoshopcafe.com/cs6/Photoshop3D-CS6-KN.html
Major problems I had with texture mapping, as the windows of the buildings were always displayed too large and blurred.
The quality improved, as I made my own textures from CG textures.
It was a very long and frustrating way to finish this work. But the result is nicel and I am inspired to continue. Maybe.
