3D models of different sized hexagon-shaped domes & all three domes in a park configuration. 

The meshes are fairly high poly so it can be used for close up renders or animations. The shaders that you see in the renders were created in Blender cycles. 

In all the sizes there is an underground passage. For the biggest dome, there are two underground passages. 

These models could work well for further project development. You could create an art gallery, greenhouses with plants etc or anything you can imagine.
