- Functions can be daunting at first, but they're a key step to mastering Substance Designer. This video series aims to make it easy to get started with functions, using simple bite-size usecases.
In this third video we combine what we learned before with random numbers, and how to transform ranges of numbers into different values.

Wow this video series was incredibly helpful. Thanks!
Glad to hear it!
very helpful
What if I want to shape splatter random shapes based on this, like a for each loop? As of now I can't get it any closer than making a random seed in my warp noise, but I cant do much with it.
What If i'd like to generate a random exposed parameter to use in my graph? Since version 12.4 Random Seed has such a button to generate random seed.
In my graph I have a bunch of warps using different noises and i need to be able to generate seeds for each of them individually via Exposed parameters. Probably with a button.
Can we get more pixel processor tutorials?
Noted! I like making these, but we have such a huge range of user levels to cover, that the advanced stuff isn't very high priority..
So Random seed is not actually random ? ? ? OMG. Anyways, thanks.
Almost never is, it's more "pseudo-random".
You lost me on the very first step - how to turn the value processor node into a "float node with a value of one". When I add a value processor node to the stage it has a zero on it.
I'd not used functions before, hence me watching this tutorial, but I eventually found out elsewhere how to add the float node to 1 to the value processor function by accessing the HIDDEN right click popup menu to edit the selected node, which opened up a whole new graph view within the previous graph view window, and which also created another "sort of "tabs" text view indicator along the top of the window allowing me then to toggle between the two graph views.
Your slightly condescending tone didn't help either, lol.... we are not stupid, just ignorant of the "masterful" UI design within Substance Designer!
Hey, sorry to hear you got lost. Did you watch the first 2 parts? This is part 3 in a series that's definitely not meant for beginners.
@@Substance3D I'm not a beginner, but thanks for the thinking about me, at all, lol. Keep up the good work (thinking about your audience that is), and perhaps empathize more with viewers actually in your videos, with more detail, and with your tone, and adding broader content in your explanations, if you gloss over something, at least make an effort to say a few words about how a viewer might catch up. The rest of the video was easy to understand after you skipped over the first step, as I already said, although it consisted of what I now expect to see in Substance applications, which is a typical long-winded overly complex workaround for limitations in the software, this particular the limitation being that the only random node in the function part of Designer only outputs decimal fractional random numbers from zero to one, which is kind of limiting in the real world of creating textures, but if you spend long enough with the little blocks we are supplied, you can build a lot of things. (My particular challenge was to generate random integers from 1 to 6 to randomly flip out a texture switch node, something I finally got to work after spending half a day on it.)
As I said, I'm just a beginner to Substance Designer's function nodes. You seem to be a beginner at creating tutorials, and at using graphics software though, lol, I suspect your mistake is thinking that the fool(s) in a situation where a software UI (and tutorials on its use) are hard to understand is/are probably the user(s), not the software designer and tutorial maker.
(PS I think by far the most annoying thing about Substance Designer UI apart from the hidden very important inconsistent popup menus all over the place, with their connected checkbox, slider and data entry panels, and the magical vanishing sort of ghost "tabs", (without the full tab graphics and UI though), is the fact that the only way in the main window to have multiple layers of textures is to composite them one at a time, with alpha. I thought I was missing something, till I inspected other people's Substance Designer graphs, lol.)
Texturing is only a very small part of the whole process of making (and selling) 3d renders, and as a freelance artist, I do it all myself, so I go for long periods not using Substance Designer, and for that reason long ago I've built up what is now a page long "cheat sheet" to remind me of the many weird hidden non-intuitive and non-standard interface gotchas and processes in the software.
I think there is only one other software that was once in my workflow for a few years that is more unpleasant to use than Substance Designer (and to some extent Painter), especially after being away from it for any length of time, and that is Xgen, but thankfully I've finally replaced that with Yeti and Bifrost.
