Quote - I am lost here.... what was created?
The dials are built into the program.... If I photoshop an image, can I claim ownership of the image?  I thought if you reword text from an author it was still considered plagiarism. 

The subject in question is not a product.... For it to be a product, something must be produced.. 

If this were about a tutorial on how to use the shader room, that would count as a product.

Get a grip on yourselves..... 

I create images in Photoshop every day.  The brushes, patterns, styles, filters, pen tools, etc, are all parts of the Photoshop software, just as the nodes and parameter dials in Poser are part of that software.  Photoshop does not create those images; I do.
Poser does not combine those nodes, or pose that figure, or spin those dials to create that character. 
These programs do not create these files, they provide us with the tools to create these files.

The answer to your question is yes.  If you create an image in Photoshop, you do indeed own the copyright to that image.  However, if you were to use Photoshop to change an image that was created by someone else, and then give it away or sell it without permission from the original artist, that would be a violation of copyright.
As for whether or not material and pose settings created in Poser are actually copyright of the author of the file, or if the file format itself negates that, is something best answered by actual copyright attorneys, and not laymen such as ourselves. 
However; the original question had more to do with social repercussions of violating the terms of use of the item.

This brings us to the real issue here:

Even if it is legal to do something; does that mean it's also ethical?

When people create files to share with the Poser community, they have every right to ask that those who download the file show them the respect of adhering to the terms of use of that item.
If there  are restrictions on the use of that item for non commercial purposes, then those restrictions should be respected.  If there are distribution restrictions, then those restrictions should be respected.

When someone unjustly criticizes a well respected member of this community, someone who has earned this respect, through years of sharing his wealth of knowledge about this program, and provided so much to this community, as SELFISH, or GREEDY; DAMN SKIPPY it's gonna cause a "stink".
