This set of 3D parts is delivered in several formats from OBJ and FBX to a "InsertMultiMesh" IMMbrush file for ZBrush allowing you to accelerate your 3D design workflow like never before. In order to optimize rendering setup the models in OBJ and FBX files are split per shader for easier materials adjustment and parts selection per material. This will come in handy whether you use Keyshot, Vray or any other rendering software. In order to optimize 3D assembling workflow the models in FBX file maintain their original Pivot coordinates. 

Unlike the “raw-mech” style parts of the non-SUBD “Black Phoenix” and "Black Widow" Kits, the more organic “Ultraborg” kits will be perfect for accelerating design work for robotic characters or mechanical accessories where a more organic flow is required. An artist will also be able to take advantage of quad-based topology of the meshes by adding additional subdivisions when a higher resolution render or close-up is required.

"ULTRABORG" SUBD Cyber Muscles Pack contains 25 unique models. Most of the muscle designs come in straight and slightly curved form so an artist will be able to either use a pre-curved version of a model or come up with his/her own cyber muscle rhythms from an un-curved mesh by utilizing Bend modifier or using a variation of an FFD/Lattice tool.
