Pendant Jewel designed by me. All the preview images were rendered with Cinema 4D, using the Redshift and advanced renderer. (classical render)
This model was created in Cinema 4D No 3rd party plugins are required.
Warning: Depending on which software package you are using, the exchange formats (.obj, .3ds .fbx...) may not match the preview images exactly. Due to the nature of these formats, there may be some textures that have to be loaded by hand and possibly triangulated geometry
