The sub-shaders, I don’t see how to do any noise generation nodes or custom script nodes basically, if I could make like a function/script node that outputs values and custom uniforms to tweek just for them like what shaderfrog is showing then yeah I could do it with the nodes.
But right now it seems it would be easier to just do it as a custom shader.
Yep. We won’t have loops for v1
but we’re getting there it looks like 
(Dave you have been killin it, thank you!)

So here are the first steps of doing it as a shader.
Here is a little bit of tweaking to the first part:

Now to do the colors.

There are a billion-zillion ways to color it…
Looking awesome! Thanks for taking on the challenge.
Am studying your code to see how you translated ShaderFrog format (or three format i suppose) to BJS. I take it by your comments above (and looking at the code), that there isn’t a simple conversion methodology (eg: A goes here. B goes here. Change name of uniform C to D, etc). In other words, was no straight forward way to copy/paste/minorly-modify to get working in CYOS?
Not when the shader was built as a node based shader no, not really… I mean it is possible though, I will work with you right now to try to figure that out if you want.
First step we need to see the shader code for the sub-shader nodes, wanna help me hunt that part down?
Sure thing. Only thing is I just started learning about shaders last week… so it’s mostly greek to me (first time i hear about “node based shader” in reading this thread this morning). Assume it’s due to the way ShaderFrog composites shaders? But yes, absolutely up for hunting/learning…
Oh I found the code int he CYOS that you posted… give me a second brother!
Looks like it was composed from:
Big Wiggles - ShaderFrog.com (Big Wiggles)
and
Configurable Oil Spill - ShaderFrog.com (Configurable Oil Spill)
Is that what you meant by sub-shaders?

There is some weird stuff coming out of this, but I will get it figured out.
Thanks for finding those they might help troubleshoot this.
Ahh its because I was using a ICO sphere:

Cause The Monkey King <3’s you for posting in this thread!
In all honesty I just learned something by converting that (about using multiple functions that cumulatively effect the main output) and validated something that I was unsure about (that we have a shortcut to the position matrix without all the extra hubbub).
So I appreciate the challenge!
You are a god among men.
I am now set to study your code for rest of day so I can figure out how you did it. Also, just by a quick line-by-line comparison, it seems like converting from the Shaderfrog Three format to BJS could be workable via a conversion script… as in: everything(?) has a predictable/consistent format from one to the other. Think I may try to write a converter if this is the case.
yup, and if you need any help on what’s what let me know.
I started doing something like that a while ago for Shadertoy, but then IQ yelled at me and I kinda lost all motivation…
Its kinda shitty when your idols turn on you.
aFalcon likes Shader Talk vmuch. Will deepdive breadcrumb trail someday. Thank you Monkey King.
Who IQ?

Impressive
…clicked this IQ YouTube sub so fast it broke the bell…
link perfectly represents life mission…
is just a parabola? oh snap!
Gr8 “mathamagics” link. Thx.
will someday drop it into https://www.desmos.com/calculator/ to see what happens…
GRAPH TOY!?!
I’m still not able to update the doc due to the “direction” parameter, see my message here. If possible, I want to PR with an exhaustive list.
Where does “direction” comes from? I don’t think we have a built in with this value
