How would I give a texture (left) a procedural spiral effect using the vector (right)?

Node Group
to start, let's create a node group to keep things organized.
- Go to your Shader editor and add a Vector Math node.
- Select the Vector Math and press Ctrl+G or right click and select Make Group.
- Optionally use the N-Panel > Group tab to set useful info like the Name and Color tag.
Spiral Nodes
Here's what the setup looks like:
We start by setting the vector Math node to Length. This results in an output inverse of a Gradient Texture set to Sphere, but without clamping.
Then, the Length output is piped into a Vector Power (see below) and Vector Multiply node. These are used for configuring the shape of the spiral.
Finally, a Vector Rotate node set to Euler. The real magic here is that all we're really doing is rotating the input vector, but at greater values the further we get from the origin, which is what the Length node is for.
Vector Power
Since the Power operation (currently) isn't available for Vector Math nodes, we have to do use a regular Math Power for each axis:
The End
I would use "Conclusion" instead, however, that term has been regrettably ruined by AI chatbots
You can create some interesting effects by playing with the values:

This Q/A post is an experiment in creating detailed breakdowns of nodes I've created and compiled into a useful, refined library. If this was helpful to you, leave an upvote or star on Github and I'll make this an ongoing series!

$\begingroup$ What does "answers to questions asked only" mean? Stack exchange promotes self answers as far as I can see. If that's meant to mean avoiding duplicates then there is one that is similar, though the idea was to apply it in a broader sense. $\endgroup$Zentheon– Zentheon2025-04-24 08:36:32 +00:00Commented Apr 24 at 8:36

$\begingroup$ @JohnEason this is an interesting subject: is creating duplicates intentionally (not sure if OP knew it is a dup), an actual violation of site's rules, or are you allowed to do that, with the posts simply being closed as duplicate (which won't interfere with OP that is posting Q/A at the same time). Of course a better place to discuss this is meta. Personally not only I don't mind, I think it's cool to see someone enthusiastic about Blender, creating a cohesive "series" and it should help the discoverability of former posts linked as duplicates. $\endgroup$Markus von Broady– Markus von Broady2025-04-24 08:45:19 +00:00Commented Apr 24 at 8:45

1$\begingroup$ It sounds as if you were suggesting posting a series of tutorials preceeded by an initial question. If so, this is not really the right place for it. - Single questions answered by the questioner are fine as they often answer obscure problems but I'm not sure they should be a regular feature here. $\endgroup$John Eason– John Eason2025-04-24 09:13:00 +00:00Commented Apr 24 at 9:13

1$\begingroup$ @MarkusvonBroady I agree that enthusiasm about Blender is a good thing but am not sure that posting a series of Q&A tutorials here is a good thing. $\endgroup$John Eason– John Eason2025-04-24 09:16:33 +00:00Commented Apr 24 at 9:16
