Remaking this thread as I thought there was interesting things brought up in this thread and it was lost in the forum rollback

I understand how they made the brushes, then converted it into displacements, but I cant get the subdivide to look anything like it does in hydro. I never knew how complicated it was. My only guess is they may have used brushes to help shape the subdivided and then deleted them.
I just think finding out how would be a good learning experience for pretty much everyone.

I know that with Nucleus, iikka used guideline brushes and deleted those. That's probably your best option. I'm not even actually sure how I would go about subdividing to create that shape honestly.

Also, as Yyler said, it's always good to place a couple reference/guide brushes during "construction" of complicated yet symmetrical displacements.

2) Make 3 copies of this arch and place them at 45 degree angles. I've found that it helps to surround the arch in a skip brush before copying it. To get a brush at a 45 degree angle, just eyeball it. Use the x at the center of the brush to help. The end result should look like this:
You can stop here, but you can go further to split it up nicely.
3) Rotate the whole thing 22.5 degrees. The intersection points of the arches should lie on the lines of the grid. Then, clip along the two grid lines that hit the center. An individual arch should look like this:
4) Cut again on the 45 degree lines. Each piece should look like this:
5) Ungroup each arch and trim the fat. It should look like this when you're finished:
Here's a .vmf of the result above.

Why be imprecise? This means your 22.5 degree rotation comes out a lot nicer, too.

This way you can have a much rounder bowl without having to limit yourself to 45 degree angles and cutting.
edit: extra

Also I swear there was a thread about doing this displacement style...

Not sure if that would be easier.

Thanks Ravidge and Idolon. Those are both good methods, and i gotta try them out. I've been fooling around my own that does what I think vavle did (well, not really but sort of). So I'll post that once I get it working 100%.
Edit: I also have a question for Ravidage, How did you tilt the arch, did you just use the vertex tool and lower the top vertices? Or is there an simpler way I'm missing, because that seems really time consuming lol.

Just bear that in mind when making your arches.
