Creo 4.0 Appearances look terrible in "samples"

[KenFarley]

We recently (last week) switched from Creo 2.0 to Creo 4.0.

I have a number of appearances I've used for years that consist of a basically "white" (equal parts red, green and blue) color with a distinct highlight. It gives subtle coloring without being gaudy, accentuates curvature, etc. With Creo 4.0, when I attempt to define the appearance of a part, the "sample" depictions of the different selections does shows more of a black blob than a nicely colored sphere. See the image below for an example.Is there something I'm missing (settings, etc.) that is keeping the Appearances menu from showing a useful representation of the appearances I've defined? It's kind of hard to select a particular one from a bunch of colorless blobs.

I had a somewhat similar issue when we went from 2.0 to 3.0.

I found if I removed the config.pro option pro_texture_library it solved my issue.

Not sure yours is the same problem but it might be related.

I checked my config.pro and I don't have that particular parameter set. But, that doesn't mean they haven't added some sort of default setting....I'll have to investigate.

On mine it was the path to the graphic-library. I sort of assumed it was something we had copied over from PTC files in the past and instead of installing the those things on everyone's machine, they set it to a network folder.

I never researched past that to see if there was something in that path that "darkened" all the colors but it made a significant difference in how the color balls showed in the appreance editor.

*edit*

The way I figured this out was to take my config.pro and cut it in half and isolated the problem. Repeated that process over and over until I was down to about 10 or so options then looked for likely culprits.
