One of my complaints about the Engineers material gathering process (besides the randomness) has been that you can only get certain materials from certain activities. It has been suggested however that most materials are available as mission rewards, meaning that being a mission hobo (jumping from system to system, taking missions with material rewards as you go) could be a viable path to upgrading your ship. So I noted down the materials for 4 different blueprints (13 different materials in total) and got to it.
Having tried this approach for the last 3 days of play I can say that this is if anything even more frustrating than doing the intended tasks. You are completely reliant on luck to get the correct mission rewards, and with 130+ to choose from (I even got some rewards that aren't in Inara's list) it will take forever to get what you are looking for. I started to resort to mode-switching at each station, which helped cycle through different rewards, but even then I would rarely see anything of use. And I certainly wasn't enjoying myself!
So spare yourself the grief, just go and do whatever it says on the tin that you should do. At least then you are only praying for a lucky drop among 5-10 alternatives instead of the full list of 130+!
