The colors are material colors. The file consists of six objects, Body, Head and four Rotors. The head of the drone can be extended and rotated to convey certain emotions. The rotors can be rotated as well. The animations are only for the rotors, and they are exactly 30 frames long.They are also loopable.
The animations will only work with file formats, that are able to store animation data: .fbx (Autodesk, supported by most 3D programs) .c4d (Cinema 4D)
Only the following file formats work with materials: .fbx (Autodesk, supported by most 3D programs) .c4d (Cinema 4D) .dae (COLLADA)
The following file formats are also available, but they wont include correct materials (due to file format limitations): .3ds (3D Studio) .obj (generic format supported by most 3D programs) .dxf (AutoCAD) .stl (stereolithography CAD)
Similar drones and robots are available under my name.
