They use UDK for lighting because you are expecting to know a game engine for most jobs. It doesnt have to be the engine that company is using, they just need to know you can navigate engines and have skills to use the tools. It's far better to be able to show a level in a game engine than in max or maya. Looks better on…
mikiex: I agree! Konamis Fox Engine, Square Enix Luminous Engine and Capcoms Panta Rhei Engine. Very happy to see they are finally catching up. Hopefully it will bring back their self-confidence in game creation.
ChatGPT, so as other similar software, is not AI. Not even close. It`s just a glamourized T9 mixed with well structured but biased search engine. It has its use only because 'Google search' is just pure atrocious garbage that is getting worse by the day.
File formats are interchangeable, the engine is most likely the same, it was gamebryo(which is a rendering engine) that they replaced with their own stuff.
