Really, dude? You go do it then. You have an hour. 10 ships. Starting now.
Well, sure just give me one of them fancy Hollywood super computers and an hour of lead senior designer pay.
Good CGI isn't something you whip up in "an hour or so". It costs money. The software is often proprietary and expensive, but really its about man-hours. You have to pay people to do it, and it takes time. ST: Next Gen was one of the most expensive shows on TV at the time, and things really haven't gotten any cheaper.
Well, what about ''average" CGI or just "ok" CGI? Way back in the '90's, like 20-30 years ago, with like Windows 95, they could make computer generatated fleets of diffrent ships. Why is it so ''impossible" in 2020? And even if computers are ''so" expensive...why not just use ''cheap" models...like remember back in the 90's when they used Halmark x-mas tree ornaments for models?
