Paul Smith' Fuzz "Gradient along Strand"

[sant0s]

hey there

I am working with the Fuzz tool to get some fur.
So far its a great tool and easy to use.

But - the "Gradient along Strand" Node does not work for me.
I plugged the Node into Standcolor (and for testing purpose into color) and in my color diffuse I pluggerd the color_attribute node with either Strandcolor or Color choosen.
But whatever I try, I dont get the strandcolor.
Could anyone test the fuzz plugin with the color node? Maybe its an Softimage Version Problem?
Running 2015 SP2.

Thx alot!
sant0s

edit: okay, the gradient to color node works fine with version 1.0.
will figure out whats the problem and give feedback here if any has the same problem.

What renderer are you using? (I'm not sure if mental ray can use color array ICE attributes)

[sant0s]

hey rray
its working - am using SitoA.

Hi ! Haven't reloaded that tab With Arnold it works indeed

[sant0s]

also with version 1.1?

[rray]

Don't know about that, with "it" I just meant the "ICE color *array attribute to hair shader" thingy

[sant0s]

ahh, compreendo

[sant0s]

maybe somebody can help with another question on FUZZ.
I cached frame 1 of the strands to get rid of the flickering. (thx to ivan vasiljevic btw)
but in the middle of the animation, I need to let the fuzz grow a bit.
is there a way to do that?
I only find the attribute "readpos" that seems to be related to the length, but thats not working

You can easily make a compound to grow the hair after the cache.

You'd need to multiply the strand position in relation to the point position.

[sant0s]

easily is relativ

but ll give it a try, thx.

[Pooby]

Sorry, yes of course. I meant that it's easily achieved. Obviously that's if you know how to manipulate vectors.
If you have trouble I'm happy to make you a compound.

[sant0s]

hmm, only if you find some time - I could just finish everything than ;)
I tested to change the length compound IN the fuzz compound.
but vectors and matrix is another world

[Pooby]

here it is.. Look inside it, as you'll see that it is very simple.

and watch this video I made for you to understand vectors

[sant0s]

wow, dont know what to say...!

the explanation is fantastic. will fiddle around with that.
an I just did a growing test and it looks so amazing!!!!!

thank you very much, paul.
send you a pm.

[Pooby]

This is your second lesson in vectors.

I'll be giving you some homework soon

[sant0s]

plop
realy helping me to understand the magic behind vectors more and more.
just playing around to get into it.
i am looking forward for the homework
