/3/ - 3DCG

Hey I am using C4D and I am trying to model a controller.

Pic related is a 3D render of a software that looks like this http://img5.abload.de/img/refx20nexus20v2.21wfl.jpg and I wanna do something similar.

The problem is that idk what to search for in Google as this is a rather unpopular thing people would request tutorials for.

I already modeled simple 3d characters for an autistic meme channel on YouTube but I still have no idea how to modify the "roundness" of corners, how to slice little stripes off the rotary knobs to make them look more "grippy" and "real" and I don't even have an idea how to make a basic button model like the orange ones in the middle of https://www.thepixellab.net/wp-content/uploads/2016/06/Free-C4D-3D-Model-Button-Kit-Knobs-Dials-648x532.jpg

Not expecting anyone to do my homework or to explain it in detail but if you could just give me some keywords so I know what to search for or if you could tell me what c4d tools I should learn that would be awesome.

I am not trying to get employed by Blizzard and I will certainly dig more into 3D modeling but for know it's just the simple things that I'd like to learn. I do know how to generally operate C4D, I am not a total newb
