Mudcliffs is a package with 8 photo realistic mud cliffs. They are very detailed, with high resolution textures at 4096x4096. They have a diffusemap, and a displacement map rendered from a high-res version of the stone. (400.000 polygons and sculpted details) The mesh itself is 20.000 polygons. They also have a bump and detail map made from procedural shaders to give ultra high detail even in closeups.
They work really well with most scales, from medium, human sized, to massive cliff formations. Every face is completely unique, so you can create very large scenarios with only a few pieces, by rotating and scaling them.
The props are set up for Poser, but can easily be loaded into most 3d applications for someone with intermediate knowledge of 3d programs, such as Das Studio or Vue. They also have distinct shaders in Poser, and if you scale them, you need to make sure to scale the values of the displacements and bumps as well.
