Hi,
The computer game mentioned was released about a month ago and already has an active modding community in the Steam workshop.
While I am sure that, HBS, the company that produced the game are acting with respect for your copyright(s), one or two private individuals have scanned images from your PnP sourcebooks and have uploaded them to Steam workshop as usable graphic assets.
Personally, I feel that allowing us to use the images in user generated content for the game would have a reciprocally positive impact on your own products, but I have no desire to risk acting contrary to your copyright or to risk tarnishing HBS and their computer game by doing so without your approval.
I would appreciate it if you could post a resolution to this question, preferably on Steam, so that the computer game community knows how to act with integrity with respect to your rights.
Thank you in advance, Latt Ice (concerned modder).
