Syagrius…. I am ‘ultrawarrior’ on the Hirst arts forum. I have many posts there, if you have the time check out some of my builds. Currently I am painting up the better part of the Hirst mech terrain. They will be posted here on this forum in the terrain section once I complete them, as well as on the Hirst forum. I have been casting plaster blocks for as long as Mr. Hirst has had the molds out/available. I totally agree with you casting is also a hobby in its own right as well. I also totally understand the space issue. Who would have thought that miniature models/figures that are about 2 inches tall would be such a space consuming hobby? I will have to check into using some layers to make a cool back drop as suggested, I have been needing something I can use for years.
try the link below, hopefully it works for one of my Hirst arts posts:
