If you've worked with nCloth longer than 10 minutes, you'll notice that your cloth can get, for lack of a better term, bouncy. It's sloshes all around and keeps bouncing and moving, even when the character has stopped. A few things can prevent this, but the main one is Damp.
What is Damp?
Damp diminishes the movement of the cloth by dissipating it's energy. Higher damp = less energy. Be careful with this though. If your Damp value is too high, your cloth can look gummy.
In previous versions of Maya, you could paint certain attributes like Thickness, Friction, Bounce etc. So if your cloth had a Friction value of 1, and you painted a third of it black, a third of it 50% gray, and a third of it black, the black section of the cloth wouldn't have friction at all, the gray section would have a friction value of .5 and white section would have a friction value of 1.
Now, in Maya 2012, you can paint more attributes, like Damp. I've been waiting for them to do this FOREVER! I'm so excited! Yay!
Painting attributes on cloth can be a huge help in getting it to behave properly. When one part needs to behave a little differently than the rest of the garment, painting the attributes could be just the trick to getting this to behave properly.
I'm creating a tutorial on it, so look out for it.

Simulation is like awesome icing
It's a hard line to walk.
You kind of want no one to notice hair/cloth/fur work in an animated movie. Unlike great animation, great simulations should go by unnoticed. It's supposed to add to an animated figure, not detract from it.
Meanwhile, you kind of want people to notice it. I saw Shrek 2 when I was 17 or so and I was amazed when Charming took off his helmet and did his hair flip. It was so beautiful to me. Or the hair work in Advent Children. Phenomenal. Even people who don't know a thing about animation or simulation comment on how well Tifa and Sephiroth's hair looks and moves in that movie.
I guess character simulation is a lot like icing on a cake. Plain cake is good. Cake with icing is awesome. When you eat cake with icing though, people usually don't comment on how great the icing is, just how good the cake is. If the icing is bad, people say the cake is bad.
It might be a little strange, but when a group of people watches a shot I've worked on, and no one comments on the hair or cloth at all, I take it as a compliment.

Cloth Cheat #2
It's been a while since I've talked about nCloth, so let's do that now.
I hope you all know about face normals.
No?
Well, a normal tells you what direction a face is facing. You can see them by going to Display > Polygons > Face Normals. See those green things on one side? They're normals, telling you which direction the face is facing. (Hide them by going to the same place you went to make them appear).
The direction of your normals is really important when it comes to cloth simulation. Normals should always face out, for collision objects and cloth objects.
Why? Well, when you apply nCloth, and you want to adjust an attribute like Thickness, nCloth assumes that the normals are facing out and so, the thickness grows outward, in the direction the normal is facing. If your normals are facing the wrong way, your collisions will either fail or won't be nearly as accurate as they should.
Why? Let's continue to use Thickness as an example. Say you have a body and an article of clothing, a dress. Oops, the body's normals are facing inward. That means, the top of the body has no thickness. The dress will sink through until it reaches the thick part of the body, which is inside!
Indecent exposure. Pretty sure that's a no-no for any animated shot. (or maybe it isn't, in which case, I kinda want to see what you're working on...)
And this is just one attribute. Many other attributes depend on the direction of a face.
So what's the cheat?
Say you forgot to check your normals before you made your garment nCloth (shame!). You can't change them after the fact unless you remove nCloth, change the normals then reapply nCloth. What do you do now?
Cheat.
Let's continue to use Thickness as an example.
Instead of making the Thickness value 0.5, make it -0.5.
The thickness will grow from the bottom of the face rather than the top. It's a great cheat, especially if you're only working with one article of clothing.
I'll let you in on a little secret. If you look at the longest shot on my demo reel, the shot with the Nobleman and the Scribe walking away, I had to use this cheat on the Scribe's sleeves.
Whoops.

Depressing in a funny sort of way
I've gotten decent feedback on my demo reel. I've been given amazing tips on how to improve it, but I've also been told that the work that's in it is good. That makes me happy. What's a little depressing is that I get comments like, "Wow, if I'd seen this a year ago, I could have hired you. It's a shame that we don't have the money to bla bla bla". I've graduated, I have a decent demo reel, the job market sucks.
Then, you get industry people who get mad at people in my position when we want to offer our services for free, or for a reduced rate. It's not like I can go barging into ILM and demand 95k a year with no experience.
I think that's what's bothering me. I'm at the point where I just want to start doing what I love to do with other people who love doing what they're doing. I want experience in my field. I want to work, and getting paid would be nice too.
Ok, before you look at me like I'm insane, please note that I know people don't go skipping into work every day and hum a little tune as they work 10 hours straight. I don't have any illusions that work will be any different from school, where you slave over something until you beat it into submission. That's fine. But at the end of the day, I put my blood into learning a skill (that I love), so I could do what I love and share that passion with other people.
I shouldn't whine. I'm not one of those people that's been out of a job for 3 years and has a family to support. I'm a recent graduate who's only been seriously looking for work for about 6 months. That's normal, right? I should just be patient, keep getting better at what I do, and at some point something will happen.
Right?

Grad Schools and Job Hunting
Yep. I'm doing both at the same time because I am a glutton for punishment.
My family and I drove to Savannah, Georgia which is where SCAD university is. It's about a 2 hour drive from where I live to where my family is, then another 8 to Savannah.
I updated the resume section of this blog, finally, then I went on a two hour tour of SCAD in Savannah, Georgia. It's an amazing, intimidating place, at least it was for me. I come from a school where there aren't 50 animation majors, and of those >50, only 3 or 4 were interested in Effects Animation. There are hundreds at SCAD! Instead of one floor, shared with several different majors, SCAD has an entire building dedicated to animation and visual effects! Their campus stretches across the entire city of Savannah, and they claim 10,000 students spanning across three or four different countries!
It was phenomenal to be surrounded by all of that, knowing that everyone there was attempting to get a degree in a creative field. Could I be one of them? I also want to look at Texas A&M's visualization department, which I hear is amazing.
I think I'll end up driving over there sometime in September or October (when it isn't dead hot outside). I'll have the time off, since I've decided not to start grad school until January.
I also won't be going to SIGGRAPH this year. :( It's an issue of money, and me not having any. Well, what can you do? I can take this time to lose some weight, get some good stuff on my demo reel and work at a Taco Bell or something, so I can save up money for my trip to Texas.
I'm also still looking for work. I'm sending out my demo reel, still learning Python, still working with Maya Fluids (ugh, shoot me now. It's so hard! lol). I applied to ILM, so wish me luck.

Think Outside the Knot
I don't know how many people are familiar with the story of Alexander the Great and the Gordian Knot.
An oracle told the people of Phrygia that fighting would end in their region when their new king arrived, riding on an oxcart.
Well Gordius, his wife and son (Midas!) arrived in the town by, surprise surprise, oxcart! The people trusted the Oracles word and made Gordius king. In gratitude, Gordius dedicated his cart to Zeus and tied it to a pole with an intricate knot. This was the Gordian knot.
The Oracle said that who ever could untie it would rule all of Asia. Many people came, but none of them could do it. Years later, in 333 BC, Alexander the Great came to Phrygia, now named Gordium, and tried to undo the knot. However, he couldn't find the ends of the knot to untie it. He became impatient and, in a fit of boldness, he took his sword and cut the knot in half.
For all of you people who slept through history class, Alexander the Great went on to conquer most of the known world, including Asia.
What in the world does that have to do with anything? Usually when someone uses the phrase "to cut the Gordian knot" they say it to mean act decisively and with boldness.
I've always taken the phrase to mean "think outside of the box".
It's hard to do that, especially with deadlines looming and grades at stake, but sometimes that's the only way to get something to work. Sometimes, it can actually save a lot of time and work out better for everyone in the end.
There's a story floating around the production of Pixar's The Incredibles. They needed to make the giant wave near the end of the movie. Brad Bird said he didn't care how it got done. If they needed to, they could make a giant wave in a swimming pool and comp it into the movie. Obviously they didn't do that, but it proved that he was open to doing something different to achieve a result.
When presented with a problem, try to think outside of the box. Cheat! Fake it! Everything we do is fake, so a fake fake isn't going to hurt anything if it looks good in the end.
Think of how much more we could learn if we were willing to look for alternative solutions.

Pixar's Brave - Teaser Trailer
I'm ridiculously excited for Pixar's next feature length film, "Brave". Not only does it look stunning, but it's the first Pixar movie to star a lead female protagonist. It's set to come out Summer 2012 and there's already a beautiful teaser trailer for it. Watch it in full screen and full HD!

FakeDYN - amazing script
So, Remi Cauzid is my idol for the moment. He's created a tool that 'fakes' dynamics in real time. He's explained what it does himself, so I'll just quote him:
I'm dying to figure out how he did it, but one thing at a time. I'm still working on my hair creation tool. Anyway, watch his video demonstration here, and be sure to comment under his video on Vimeo.
A script I have developed for my rig in Maya.
Super fast, the dynamic result can be seen in real time in the view port.
I am using a simple expression making a delay in position on a locator. Then I am using different locator to drive the chain of joints.
One chain of joints is used as an input animation, and the other one is the result plus dynamic on it.
There is possibility to change the damping, the springiness, add some force to simulate a gravity or wind, and add some random noise to the movement for a more organic result.
I am mainly using this in my rig for animal ears, tails, little pieces of fabric, but there is many possibilities as it is shown with the carriage.

Updated this theme
People who know me from school know that I change my desktop background one or two times a week. I don't like looking at the same thing for a long period of time. That's true of blog themes as well. It was time for this one to change again, so I made it look like my Tumblr account (which you're free to see at http://pozest-star.tumblr.com/).
I figured out the rounded edges and the transparent post background, but now I need to make it white instead of black, and I need to add the border. Whatever. I'll do it later. Maybe.
