Does anyone know how to create a Towel or Terrycloth material? Is this something that should be done with Hair? below is an example of the model just a test. but it has a burlap bag look to it instead of a towel. Any suggestions or donated materials much appreciated. I am not getting paid for this just helping out a friend and will donate all models and projects to the community when finished.

Thanks guys

Helping out a friend
This is his product.
This is the motion graphic representation I made of the logo for him. I had to do the sprite like light paint strokes via apples motion. I think it can be done in am but until someone shows me how motion is extremely simple. The rest was done in AM.

Thank you Rober, anything you need let me know.
-
Any one have a material or suggestions.
-
Thats impressive. Did you use a force to give lift?
-
The cloth material isn't part of the model so I can't really test it out.
But have you tried an all cloth model as a test? All cloth, no Newton. Not chains, cloth ropes.
I tried an all cloth version. didnt work

Still having trouble

Thats one of the most interesting things I have seen created with AM in a long time. The lack of motion blur gave it a stop motion feel. I kind of felt like I was viewing a skit from Robot Chicken. Did you use ibl?

Thanks for the suggestion. I dont see where the "new attached constraint" is located

Hi Folks
I have been studying Cloth and Newton Dynamics. I have been very productive results and am amazed at the power behind both of them. I have a puzzle I am trying to solve. For a few short shots in my presentation I have a parachute carrying some cargo to the surface. I was thinking because the cargo is very heavy and large that instead of cables connecting the cargo to the parachute I would use chains. I have been practicing creating chains with Newton and its very easy and works great. You get a huge payoff for little effort. Another reason why I want to use chains is they are visually stimulating more so than newton driven cables. I am not apposed to cables or a combination of chains and cables. Maybe cables connected to the cloth but chains connected to the cargo so at some point cables and chains are connected.
My dilemma is that I cant figure out how to connect the two. The cloth to the chains.I would assume that a force of wind would be driving the cloth as well as the force of gravity and momentum of the adjoining chains. The chains would be constrained some how to the cloth and the newton dynamics would make the chain react to the cloth and cargo.
First problem I encountered is that you can run Newton and Cloth sim at the same time. Maybe that would be a good feature request. Lets say that is not a problem. You can get away with simulating cloth first and newton 2nd. I tried that but it didnt work. I constrained the links to the cloth with offsets but when I simulated newton the newton chains eject into outer space. So even though you give a newton object a translate constraint it does not seem to adhere.
Any ideas or thoughts. I may be going about this all wrong. I am open to suggestions or ideas.

Ok that clears things up. Below is text from the tech reference on the subject. It seems like a whole other world that I never heard about. But I am not going to explore it based on what you folks have said. If Newton, simcloth, and Dynamic constraints are the way of the future I am not going to spend time learning a dead feature.
Soft Body Dynamics
The Soft Body dynamics available in Animation:Master are based on
systems of Springs and Masses. There are currently two ways to create a
new Spring System.
• The Cloth Wizard.
• Right-click (Control-click on Mac) [New Spring System] on an
Action or Choreography icon in the Project Workspace tree.
Springs are used to exert forces on two masses. They have a resting length
that they try to maintain. They have parameters to control how stiff they are
as well as their damping.
After adding a new Spring System to an Action or Choreography, you will be
placed in Dynamics mode: springs and masses are drawn in the window.
This mode has a set of construction tools: you can add a single mass, add a
single spring, select a mass and move it, delete masses or springs,
constrain masses to bones, and constrain bones to springs. The setups can
be saved as single frame poses, for later application to the model.
Soft Body structures react to keyframed motion and supply secondary
motion to specific parts of a model: pony tails, locks of hair, loose jowl skin,
ear-rings, bouncy noses, ear lobes, tubby bellies, etc.
Spring System Editing
Add Mode
Click on the Add Mode button on the tool bar to begin adding springs and
masses. Click anywhere away from an existing mass to add a new mass. A
new spring will follow your mouse. Click on an existing mass to connect the
spring to, or click away from an existing mass to add a new one to end this
spring with. If you do not want a spring to continue from the current mass
hold the shift key to create a new unconnected mass. Press the
key, right-click the mouse, or select the Edit Mode button on the toolbar to return
to Modify mode.
Attaching Masses
When dragging a mass you can attach it and its springs to another mass by
right clicking (or simultaneously pressing the key and clicking on the
Mac) just as you would attach two control points together. When attaching
masses, one will be removed. If you attach two masses that have a spring
between them the spring will be removed.

I thought I knew but I didn't. What I have learned about is "Dynamic Constraints and cloth" But Spring Systems although related seem to be different. I don't want to debate that part. I just want to know if there are any tutorials showing how to use the editing features in dynamics mode and assigning masses, using the constraints that are designed for spring Systems.
Could someone point me in the direction of a tutorial for this? Or could someone make a video tutorial.
In the tech ref they talk about using this for stuff that I would normally use a dynamic constant for like
pony tails, locks of hair, loose jowl skin,
ear-rings, bouncy noses, ear lobes, tubby bellies, etc.
Yet Spring systems are made so different in how they are made. So what gives? Are dynamic constraints the latest and greatest that make Spring systems out dated? What situations apply? I don't get it.

Nice tracking. With shadows, this would look very nice!
Yes I should have went the extra mile and added shadows. Maybe I will do that. It was just a test of AE cs5 roto tool and I wanted to show my friend the guy in the video how to track using syntheyes.

That would be sweet if you rendered all this in 3D. Looks like you've got one heck of a render farm going. 2 years seemed a little much, but a month is not too bad.
Yes it will be. the only live action was what was on the monitor in the beginning. OOOOOOOOOOO you mean actual "3D" not just CG. I guess I could do that and thought had crossed my mind but for now 2D is hard enough. 3D would take twice as long to render.
5 years ago I purchased special equipment 3D glasses and a special device that you hook up to your tv SD only. This was not the blue and red glasses this what more like 3D at an Imax theater with no color issues. I created true 3D, Left Eye Right Eye CG in AM Put it in the proper format to work with the 3D glasses and equipment and watched real true 3D on my home wide screen tv. At the time it seemed really cool but like a lot of cool things it was a novelty. I couldn't use this very cool work flow and accomplishment I had created to get jobs with. There was a company that I wowed with it, remember this was 5 years ago. They were doing something revolutionary. The company was called "In 3" They started their RND over 5 years ago and until recently you have never seen their work. They coined the term "dimentionalise" And guess what they Dimentionalised Clash of the titans, and that other movie with the white rabbit. Why did I not get a job there. They only paid $12 dollars per hour and it was a sweat shop. I got a feeling jobs like that will soon be in India or China. I did get my girlfriend a job there, she didnt know how to use a computer so this was a step up for her. As it turns out she is now near the top of the company and managing over 100 people. She got lots of raises. lol We broke up and she does not talk to me anymore.
What was my point. You know what that could be a huge selling point for Hash now that 3D is a buzz word again. If someone paid me which they wont I could come up with a work flow to render from AM and put it into the proper format for the samsung 3D HDTV's and 3D Blu Ray players.

What sort of ray traced lights are you using?
In the first shot I had a ray traced light in front of all 3 monitors to simulate the glow of the monitors screen, light output. The blue light on the matrox mx02 also had a ray traced light. I was not able to accomplish this effect without using ray trace all direction light. Either way that shot is done and completed now. Most future shots will avoid it.

You're looking at a little under two years of continuous render time needed to do your minute clip. Do you need that many passes? I usually settle for about 16 passes though I've seen some people use 25 for stills.
Yes I do. Without motion blur, or Ambient O rendering in SD its possible to get away with less but in my case
My specs are
HD 1920x1080
no aliasing
Ambient Occlusion can NOT crawl as it does with low samples and low passes
I have done the math and with all my procs I am looking at about a month or so of rendering because I have 30 processors rendering 30 instances. If I need to I can always purchase a few for quad core or 6 core machines to speed up the process.
When I go to an interview with a blu-ray for my demo reel at a studio they may want to project it in there on site theater. Or sometimes they play it in a conference room on a 63" HDTV.
I live in the present but I want my work to have at least a little shelf life with all the hours I have put into it.
Mark my words in 3 years they are going to be selling 2k and 4k, 100" 3D TV's
You will be able to purchase a consumer camcorder that shoots 2K or higher for less than $1000.00
I didnt put hours and hours of my life into this work to skimp on the rendering.
Of course this is subjective and my standard of quality. Not all projects like TWO for example require this level of quality. In my case I am aiming high and I hope it shows.
James Cameron aimed hi and it worked out for him.

How long is it taking you to render all of this? 1080p with 49 passes with things like AO and soft reflections could take several hours per frame.
It depends on the shot. the first shot didnt have AO but it had a lot of models. it took about 16 hours per frame no motion blur. I did the motion blur in AE with real smart motion blur. the 2nd and 3rd shot did not have as many models and lights so I was able to add motion blur in AM, do 64 passes, AO volumetrics, and soft reflections @ 50% quality. took about 8 or 9 hours per frame. The first shot had a bunch of ray trace lights, the 2nd and 3rd had mostly Z buffer with penumbra on.
