Conclusion

Texturing is an important part of CG. Only a realistic texturing can make the 3d object as original as the live action scene is, and this is very essential part of VFX especially when you want to merge the 3d object into a live action scene seamlessly. 

In the next part of the tutorial series, I'll show how rig, skin and animate the robot.
