Smooth polygons is the biggest problem. You can set your render options so smooth polys is off, but I like using smooth polys. It really improves the quality of the render. You can turn smooth polys off for individual objects, but it takes awhile, for something with a lot of separate parts, such as a house. (This is something I've run into with your models, Sharen; I love 'em, but they blow up like marshmallows in the microwave in Poser 5.)

Another problem is "reversed normals." Poser 4 will render the backside of polys the same as the front side, but Firefly will not. Poser 6 has the "normals forward" option, which can fix it. With Poser 5, there's a fix you can do with nodes in the material room.

There's also the "L-shaped polys" problem. Poser 4 didn't have any problem with L-shaped (concave) polygons, but Firefly does. It won't render them correctly, and there's no easy way to fix it from inside Poser. I have not run into this in any of your models; it's most commonly seen in Marforno's older architectural models, as "webs" in the corners of the windows.

Textures can be an issue with Firefly, too. Hair that was made for P4 often looks "noisy" in Firefly. Usually, you can fix it by fiddling with the render settings. Some people run hair textures through Photoshop to sharpen them before using them in P5/6.

The most common texture issue is bump maps that don't attach correctly. If an item was made for PP, the bump maps will not be attached correctly in P5/6. They will either not be attached at all, or they will be attached to the gradient node instead of the bump. (This is a common problem with DAZ products.)
