I made these for my own personal use after noticing that while there were some nice BFG proxies on the internet, they were not intended for use in Rogue Trader games and were severely lacking in many areas. These miniatures, on the other hand, are intended for use solely in Rogue Trader games.
I've put them on their own blog for now. It can be accessed here . Currently I have made as many Imperial ships as I can (almost all the Hulls available with the current sourcebooks), as well as most of the statted Ork ships. I just uploaded some Eldar ships today, and I'm working on Chaos next. The voidship minis I made are listed under "New Voidships", another batch of BFG paper proxies I found is also there under "Found Voidships".
I just thought some people here might find some use for these. If this counts as spam I apologize and please delete this post.
