There isn't a single set distance between the two VP's needed in order to get 90 degrees. The distance will depend on the type of lens effect you want to produce.

Here is a video timestamped to the relevant parts about lenses

In short, if you want a dramatic, distorted, look then bring the two VP's closer together. This emulates a wide-angle camera lens.

If you want to get closer to an isographic, more regular, look then you spread them further apart. That emulates a long-angle camera lens.

So, with all that said, that doesn't really help you get a good box like you were asking for. I recommend starting off practicing what is called the Y-Method. IIRC Uncomfortable mentions it in the box challenge material. In any case, the Y-method has you draw the closest corner/edges first and.

The discord has this image pinned in their Lesson 1 channel that might help:

Notice that the image states the angles between the lines should never be less than 90 when using the Y-method. (You'll also see what is called The Arrow Method for when you have a 2-point-perspective box that is placed directly in front of the horizon line. I'd say stick with the Y-method until you get the hang of it.)

I feel this video from Proko does a good job breaking down the intuitions you are wanting to develop as you draw a box using the Y-method:

It isn't timestamped exactly to the Y-method part but it is worth watching the entire segment, in my opinion, so I timestamped it there.

those links look really helpful. Thank you.

Remember that when you agree with something another user has written, you are putting your own reputation behind it.

Consider the following:

  • If it's homework feedback, does it address each section of the lesson/challenge, or only briefly touch upon one or two exercises?
  • Does it provide clearly defined next steps for the student to follow?
  • Have you read through it thoroughly, or are you simply agreeing so the student earns a superficial badge?
  • Replies you agree with will be visible in your sketchbook

Agreeing blindly just to be nice is a good way to get your permissions associated with this function revoked, so make sure that you genuinely feel that the response is beneficial to the student.

Sketching: The Basics

Sketching: The Basics

A lot of folks have heard about Scott Robertson's "How to Draw" - it's basically a classic at this point, and deservedly so. It's also a book that a lot of people struggle with, for the simple reason that they expect it to be a manual or a lesson plan explaining, well... how to draw. It's a reasonable assumption, but I've found that book to be more of a reference book - like an encyclopedia for perspective problems, more useful to people who already have a good basis in perspective.

Sketching: The Basics is a far better choice for beginners. It's more digestible, and while it introduces a lot of similar concepts, it does so in a manner more suited to those earlier in their studies.
