I want to model a Helmet, and I am attaching a photo so you can see what it looks like.

enter image description here

I wanted to know what method you would use to model if you were in my place?

And the second question, is it possible to model with geometry nodes? If yes, how I do this?

Thank you

    $\begingroup$ Hi. "Modeling problem" does not say much about the content of the question. A title like that fits all modelling questions on BSE and is useless. You should use descriptive titles. "How to model helmet of Cyrus the Great?" or something like that would communicate more. $\endgroup$ Nov 3, 2023 at 8:56
  • $\begingroup$ This task is definitely not something you should try to solve with Geometry Nodes. $\endgroup$

  • $\begingroup$ @Maxendeer if you agree with Martynas Žiemys, why don't you change the title and improve your question for readers in the future? $\endgroup$

Begin with a UV Sphere that you cut off (make it match more with your reference image):

enter image description here

enter image description here

Extrude behind:

enter image description here

Extrude along normals to give it thickness:

enter image description here

Select all these edges and bevel:

enter image description here

Extrude these top faces along normals, first with a small Offset, then a second time with a larger:

enter image description here

Result with a Shade Smooth and a Subdivision Surface modifier:

enter image description here

  • $\begingroup$ Thank you very much for your great help buddy... But I think you mean is start with cylinder, not uv sphere, right? $\endgroup$

  • $\begingroup$ @Maxendeer no it's a UV Sphere, see my edit $\endgroup$

I've noticed the first answer, just wanted to include a direction for the remaining parts.

Yes! A UV sphere is the best way to approach the big round part. No Geometry Nodes are needed for this model. Similar but slightly different approach is to use Inset on the face strips instead of Extrude

The front part can be modeled using Curve with Bevel Object, a Circle for the disk and star part and subdivided cubes for the two plates.

enter image description here

How to inset Face strips:

Select the odd columns of strips:

enter image description here

press "I" on your keyboard to invoke the Inset operator. Adjust the operator settings and add a Depth in negative direction:

enter image description here

Select the even columns of face strips:

enter image description here

Press Shift+R to repeat the last operation with the same settings:

enter image description here

Here is a screenshot of the Crown curve and the applied profile curve:

This is not a tutorial how to model a helmet but a guide on how to approach it.

Here is a .blend file with the model shown in the screenshots above.

  • $\begingroup$ Good addition! I would have used Inset as well. I would only guess for beginners it is showing way to few steps to get from the beginning to the finished result. But probably he could ask a new question when he's struggling with the parts after modelling the main sphere part. $\endgroup$ Nov 4, 2023 at 11:10

    $\begingroup$ Thanks @GordonBrinkmann. It is really hard to tell if the ridges are sharper or rounder so I went with the Inset option. There are many ways to skin this cat but I can understand the main struggle is how to start the big round shape (i.e a good starting topology) even for an experienced modeler. Nowadays Geometry Nodes are overused for modeling when Blender can get things done quickly and painlessly with simpler tools. Maxendeer didn't mentioned he is a beginner, so I hope he understood the tips. $\endgroup$ Nov 4, 2023 at 12:34
  • $\begingroup$ No, he didn't say he's a beginner, you're right. Maybe it's just because from my personal experience that in the beginning here I expected too much understanding/basic knowledge from askers which then turned out to be false. And since the goal of this site is to make questions and answers valuable for other people with similar problems in the future as well, I sometimes tend to be overexplaining things... well, as I also said, if he's struggling with something he can later ask more questions if necessary. $\endgroup$ Nov 4, 2023 at 12:42
  • $\begingroup$ By the way, yes it is really hard to tell - after I saw the image I asked Google image search for "Persian helmet", but nothing that showed up looked anything like the reference... so I might be missing a special name for this variant. Anyway, I could not find out how it is supposed to be. $\endgroup$ Nov 4, 2023 at 12:48
