Hi I feel it would be great to have a course that focus on hard surface modeling. While it may not be a hard topic as it mention I feel it be great to get a better understand of how to set it up with the use of booleon and bevel modifier. It will help to get a better understand of smoothing and using normal maps more. Many objects can be used for hard surface and not just in game assets. Of course there many great things to made with hard surface such as mechs. I know there was a session with mech but I feel a detail to add more details to it. Or even many kind of transporation like cars, planes, etc are good example to learn more about hard surfacing. I feel learning more about making hard surface as it something that is used in many assets espically in sci fi ideas.
