I don\'t believe commercial gain is required in order to be in breach of copyright. I think a copyright breach just becomes more apparent once the breacher starts advertising and selling the item than if they kept it quiet.
From GW\'s IP Guidelines:
\"Do not cast any materials that are based upon Games Workshop material. Games Workshop has to maintain a strict policy on this to fight counterfeiters. We would also remind you that reproduction for personal use is NOT an automatic exclusion in respect of copyright protection in many territories worldwide. \"
I believe that the use of a GW artwork to make a sculpt, even with some changes, would come under the exclusive right of the copyright holder \"to create derivative works (works that adapt the original work)\", as GW owns the copyright on the image.
One obvious example I can think of is the Allan C (i think?) \"daemonette\". It looked too similar to the GW version to be sold separately, though with some sculpt changes and a name change it became OK.
