This is a basic igloo-like tent created with a blender clothing simulation. The structure of the tent is modeled with NURBS and converted to meshes and used as collision objects for the outer shell. The physics simulation and 30 frames of baked data is included in the blend file. The material of the tent is silk-like an very light so it moves slightly when wind is applied.
The bench metal frame is created with NURBS.
Preview images are rendered with cylces, hence the materials are defined with the node editor.
