Creating 3D models is time consuming. Patience and skill is required in each phase of the model composition from the mesh to the texture. Additionally, adding detail and animation to make your project look the way you want also requires a significant amount of toil and talent. Add to all of this – deadlines.
So for a head start, try downloading models, textures, mocap files, blueprints and more from a 3D model service. These services can save you time, so you have time to explore your creative possibilities.
