Unable to use some content after upgrading to 4.5
For example, I have sci-fi set from Rendorisity by a vendor called 3-d-c or pgmer01. It's an apartment. I select each wall, the floors and the ceiling along with a pillow and blanket. Only the pillow, blanket, and a wall with windows will show in renders and in the preview pane. The other objects are in the scene tab but have nothing listed at all in the surfaces tab.
I thought at first that this may be something with this product, maybe something had gotten corrupted but it has happened with other stuff and not just poser-style CR2s. For example one of my Genesis wardrobe items which uses dsf files won't load. One shirt will load, everything else doesn't show with the same symptoms. They appear in the scene tab but there is nothing in the surfaces tab.
As a test I loaded up the sci-fi apartment in Daz 3 which I still keep around because I use it for some renders using stuff that never got updated to version 4. The apartment files load up just fine which means it is not an issue with the product, it is an issue with version 4.5. It happens both with content I "migrate from the old database" and content installed directly into Daz4 and pulled out of my smart content tab.
