While the sister comment is down voted, they are not necessarily wrong. AI absolutely makes custom 3d engines easier to make because the math is very well understood.

Most games do not need 90% of the features 3d engines have. A simple geometry batcher with a bog standard rendering equation and simple single directional shadow map will go a very long way. I can confirm AI has been able to one shot this for well over a year.

However, dont expect to churn out nanite overnight

You can definitely get it to make a custom 3D engine easily. I asked Gemini 3.1 Deepthink (or whatever the Ultra version is called) to make me a 3D engine that ran in CGA on 8086 XT in x86 assembler, and it one shot it perfectly with filled polys, backface culling etc.
