1. I loaded a scene I was working on Poser 7 (Pro), and though all geometried and textures loaded right, the lights were "shinning a whole lot brighter" and the displacement maps were having more than twice the displacement effect they had before. So I adjusted the lights and the displacement maps, and it solved those problems. But was this supposed to happen?

2. Hair. I use Poser's hair room in this scene, and looks like the hair renders a whole lot thinner in Poser 8 than it does in Poser 7 (Pro). I adjusted the thicknesses and it solved it.

3. The new interface looks very cool, but its heavy! On the material room (on Advanced mode), moving the nodes around is all slow! Why??

4. It CRASHED TWICE ALREADY on the first day!! I had a scene rendered and I clicked  "Material" right from the rendered image, and it crashed. Another time I was just clicking around and it crashed again. My older Poser 7 (Pro) never ever crashed on me.

Now on the plus side:

1. Looks like Poser 7 (Pro) had a problem with UVs. The UVs either had to be exactly or pretty close to the shape of the object you were applying them to, or the textures would get blurred the more the shape differs. For example: Applying a texture to a long wooden plank. If you make the plank in 3d studio to be like, 10 feet tall by 1 foot wide (1 inch deep), but your UV map template is like, 10000 by 10000 pixels, and you apply your texture on top of it, even if you consider that the real aspect ratio is 10 to 1 and shrink/stretch your texture according, Poser 7 (Pro) will render it all blurry. And the more the aspect ratio differs, the more blur it gets, up to the point where you can barely tell if there's even a texture at all. Poser 8 looks like does much better on it, or completely solves the problem (see the wood textures on the attached image, you can see the wood texture is a lot sharper on Poser 8).

2. Yes, I always hated when my scene had quadrants that were easy to render, and the others were hard, so one CPU would finish its quadrant in 10 seconds and then go take a nap instead of helping the others. Poser 8 solves that problem for good.

I dunno.. the P8 render looks much more real to me.

The lighting will change as the render engine got changed too. Add to that that Pro can gamma correct each bitmap texture you use, and you get a lot of potential subtle (and not so subtle) differences. That, and the lighting in poser 8 can now have linear and square falloff, another difference maker.

As to the material room being heavier, it is actually faster for me. Just picking a material from the viewport took seconds in pro, where now in 8 it is almost instant. At least for me.

As to the blurring effect on the textures in poser pro... You can disable filtering in the image map node (Filtering->None). But, you might get some moire effects or stuff.

Agree with Gareee. First thing I thought when I looked at the picture is that the P8 render looks much better than the P7 render.

Thats what im saying. It is better. Thats one positive thing i found at Poser 8.

 The reason why the displacement maps are larger may be that Poser is default set to inches. If you've changed your previous version to somoething else, it matters when you load premade textures with displacement. At least I think so...

The settings in preferences shouldn't make any difference...
Poser writes all values in Poser Native Units into the files and converts the values to the units
you have set in preferences when loading the file.

So it really shouldn't make a difference.
Otherwise we would have a lot of trouble with premade content...
