Is there any way to make a cave, with stalactites and such? Paper mache, with plaster? any sugestions?

I usually make a few forms out of ply or chipboard, staple some chickenwire on, then cover with fibreglass matting dipped in plaster. Then texture with more plaster. Or mix up some 2 part polyurethane foam, spread it on the plaster and matt, and watch it expand, it gives a good lava like effect. Also you can use heavy duty foil, which forms angular crinkles, then coat that with glue and sawdust, or paper mache, or ceramic tile adhesive, to soften and texture. Stalactites can be made separately then joined on and blended in. (individually, or in a mould.) Or a mix of all these methods. You can also take latex moulds off real rock if the texture is good, and cast plaster sections.

Hey thanks. I will try that. It sounds like I may be able to pull off some of the ideas.

Why do you not make a huge latex mold ( about 7 mm thick ) of a real rock . Beneath that , you make the basic shape of the later miniature formation from chicken wire . Now you put the huge sheet of latex into the basic form out of wire , so that it matches it perfect ( what may be not that hard , as the latex will fall into the form from its weight alone ) . The molded surface is lying on the upper side . Now you fill in the material , the set later shall be from . It should be light in weight and itself have some fitting textures . Now your set , when it has dried hase the shape as you need it ( it is in your hand with the chicken wire ) and has the best surface possible ( molded from nature ) . Give this a try .

The latex mold is the same thing we did for the cave in DREAMSCAPE. Jim Belohovek went back up to Bronson Cave, where the live action had been photographed, and made a mold from a large slab of matching stone. I did the Snakeman sequence in the miniature that Jim B. created. Jim is a master model maker who also worked on THE THING, TROLL, EVIL DEAD 2, THE ADDAMS FAMILY, ALIENS and many, many more.
