I think i have to agree with
www.siwdat.com stance on this.
If we dont put any drawn lines on this, how can we draw lines on the other creations out there beeing modified and copied.
The rule on SIWDAT is:
If an existing prop, licened or fanmade is altered, modified or resculpted on top of an existing peice and it is not made moulds of to recast it is considerd as a personal project. The moment the armor is moulded to replicate and offerd it is regarded as modified recast peice.
In regards of Pepakura.. The instant the peices is moulded to make several casts it becomes a "recast" peice in my opinion.
Pepakura falls in a category that is hard to pinpoint. Because they can take and outline the details by lines from ANY photo reffrence and turn it into a 3D. This is one of the reasons the Warmachine was adopted so fast due to Hottoys/ Sideshow Photos showing it from all the angles.
The pep file have primarly followed the original lines.
The big difference is that the file is offerd for free. If this was charged for we would probalby say it was LINES CAST OF...

or something.
I dont intend to offend any papakura makers, because i do admire their dedication and hard work. I do in fact look forward seeing allot of these suits finished.
But we have to have guidelines of this, one or the other way.
THE ISSUE...
I know if we made a CUSTOM sculpt and shown it from all angles that could been replicated with Pepakura 3D programs in a day.
Then to shortly after se the pepakura file maker offer it for free and tell that anyone can use it to what they want.... That would not be ok with us. I dont belive it would be with any other either.
I hope this make sence from the sculptors point of stance.
