You did an amazing job on this mannowar! A Stone mold basically is hard mold used for pulling soft parts like latex backpacks. Rule of thumb hard mold /soft pull(ultracal / latex), Soft mold /hard pull(silicone/resin).
Thanks all. Corey the sculpt is still intact, so remolding will only require some minor touch up work and a little reshaping from where I removed the silicone mold and pulled on a couple areas.. I used Monster Clay for the first time on this sclupt. It's not the easiest to work with, but overall I'm happy with it. Yes, as answered above, stone molding is simply plaster molding using Ultra-cal or similar. I'll post up a latex pull soon.
Yeah Lee, I've had a couple requests for a P1 pack and it is on the agenda. I've got a couple suit builds I've kinda fallen behind on that I need to finish up before I jump into any more sculpt work, but a full new set of P1 armor is pretty much next on the list as soon as I'm caught up.
