I recommend running the color ramp through the bump and preview that. Makes it easier to see where it clips.
For musgrave which can go *WILDLY* outside 0-1 range depending on parameters, run it through a map range then bump which is easier to preview.
Use separate.H on a voronoi if you want random values centered around 0.5; subtract 0.5 to center around 0.
Usually I only need a repeat along one edge (for procedural stuff) such as a cylinder. Can be used with 2D output -> 3D input where last is just linear.
You can use #frame/res as one of the inputs for a sin/cosine to have it loop seamlessly in time *INSTEAD* of spacial.
Don't forget we can smooth the tops and bottoms using smooth minimum and smooth maximum math nodes.

BTW, this is perfect for texture creation for games, I needed this trick for a Trim sheet based on textures created procedurally and it seems to work

Wonder why this video don't have more views. It's amazing trick that everyone should know.

ive been wondering for so long if this was possible, very happy to finally have an answer!

[zackytravis]

what is that viewer node, and how you render only the texture without object ?

This is a heckin magic, you are a sorcerer

I was looking for a way to make my own random masks for the terrain, this works great, thanks!

If one is 'Baking', using cycles bake, from a plain and using object vectors, just multiply PI by 4 at 1:32 .

EG: Texture Coordinate Node {Object Data} -> Vector Math Node (Scale) {PI *4} -> Separate XYZ Node -> Rest of Math.
Do not change scale prior to Vector Math (Scale) node, or the texture may not be seamlessly tillable.

Tested On Flat Plain, don't know about more complex objects, like cubes.
One can Multiply Pi by powers of two to get a repeating pattern in the render view but that's ultimately pointless
as one would typically only need a single pattern that is seamlessly tillable.

Thank you so much! This is such a great help. I made a group with an input node for mapping. Fantastic how I can use this to combine textures and it is still seamless. Don't understand the math but I sure can use it :)

i was about to give up on making a seamless noise texture, thanks for saving me

Whoever thought of this is super inventive...I think I understand how this works a bit.

If you plot out just the X and Y being output by the UV map U value, it creates a circle on a 2D graph.
The same thing goes for the Z and W being output by the UV map V value.

So you're essentially looping on 2 separate "planes" of 4D space resulting in a seamlessly repeating noise texture.

thanks very much, this video was very useull. In my case, I wanted to tile a large procedurally generated vine (tiled just in Y, not X), so I needed to modify it, directly passing through the X value and a complex arrange of scaling factors. Anyway this video was very helpfull.

I suffer from crappy handwriting when referring back to my notes from great tuts like yours! 👍 keep the tuts coming! They are appreciated

For all the time I've been using Blender, the performance hit from using 4D textures in Eevee was never stronger than the performance hit of Cycles as a whole lol

[SkinnyBlackout]

Man, I'm binge watching your tutorials, they're godly! Subbed.

[broever]

I suck at math and don't understand anything but this worked so well anyway, so thanks! :)

[HammerdownProtocol]

This was incredibly useful. Thank you.

[simonnesvadba]

The W's are slower in Eevee, but my PC does get more L's in Cycles. PS: Great video!

[sallo]

Thank you very much, this is REALLY helpful!!!
