## How to grow hair by color.

So I hear you ask, "How can I make soft stands grow according to a color?"
Well I answer in a kind - not to overly smart voice -  "Let me show you."

First lets look at color.

Using ICE we will grow hair with different lengths using the RGB value from a texture map. Blue being long hair and the rest being short or so on. Only problem is that some colors are not just blue they are also red like say Magenta(see color wheel below) or yellow(Green and Red) or Ocean(Green and some Blue) and so on. So we will have to compensate for that.

You can see Magenta is 255 - 0 - 255 (in ICE that would look like 1 - 0 - 1), meaning it is a hundred present blue and a hundred present red. Using an If statement that simply says if something is a hundred present blue then make the hair longer there wont really work well. So we also need to say that, if you happen to have two values that are 255(or 1) then don't use that color to grow the hair longer. If that makes sense :/

Lets look at the ICE setup...

NOTE: If you don't know how to Texture strands using a texture map, never fear. Here is a link to a post I  did  -----> texture map.

Now to get the hair to be either short or long depending on whether or not it is the color you want to be long(Blue), or short(every other color). In the ICE TREE below you will see an If statement that tells the strand length to be either short or long. Then I simply duplicated that tree for red and green values. Using the select case node you can then choose between red, blue, or green if you make a compound.

I also made a bleed option to include the color values like Magenta and Yellow using two more if statements.

Green example:

Red example:

Strands with a bleed of 0.4

Strands with a bleed of 0.8

Things I would like to include and improve:
Bleed hair has a fall off growth.
Hair grows in over time .
you can choose only bleed values.

So I will probably be updating this post in the near future.

To be continued.. :)

### Marvelous Designer 3

Started learning Marvelous Designer 3 for an upcoming job..... AND MUCH FUN WAS HAD THAT DAY! \:D/

Love the pattern making and the easy to use interface. Here is what my first skirt and bodice looks like...

 *click to make big*

Got the pattern for the bodice from a real clothing pattern, and it turned out really nice. The skirt was just me seeing if I could "thumb suck" some clothing, think I need more practice with real patterns before I can be any good at making my own designs.

Still cant wait to make more clothes !! I feel like a real dress maker *SO MUCH POWER* in this program. I also have to learn me some N-cloth and Houdini, so super exciting times ahead for me.

Here is my just importing the model into Softimage and applying Syflex.
