I have a couple of projects to do for uni, one is a game in Unity(a Doom style shooter), and the other is related to image processing. I want to get it done efficiently and as quick as possible. I have the coding knoweledge and experience to get it done on my own but don't have much time on my hands because of my work. What would you recommend for me? I am trying to save some money so would prefer something free or cheap, but if I could get a really good model that's gonna help me do the projects in like a few days I could spend some money if they make a large difference. Edit: if this sub isn't meant for these types of questions, any suggestion for other places to ask would be greatly appreciated.
