What's the hardest perspective problem there is in art?

Perspective is easy. The hardest part is setting up a grid. The rest is super simple plug n chug tactics.

Curvilinear perspective is a bit tougher, but it can be eyeballed more.

Then there's stereoscopic perspective, reverse perspective, infinite-point perspective. There was a funny pic about it too, wonder if I can find it.

It's not even hard, it's just time consuming as fuck.

True
I guess I meant it's hard to remember all of the different terms and what the process is to get to them. When you're a beginner of course.

After a while grids become natural and it'll be ingrained in memory.
