I want to get better with hard surface modelling so I found an old course (that I got for free...) on Udemy. It's a pretty decent course, altought it didn't go deeper about "subdivide the mesh" and make a high poly lightsaber. So, the basic model that I got has 12.346 tris, and the high poly version that I tried to make with subdivisions and loop cuts has 2.204.640 tris.
