ok, gonna see if i can make this simple. there is a lot more to dynamic cloth than just what im gonna try to show here, but it should(hopefully) give you a starting point. the hardest part was trying to figure out what prop to try and whether to start with premade dynamic cloth or convert a conforming one. as we are going for simple, lets use dynamic, and lets use extremely different figures to show its usefulness.
so first. get this m4 tshirt made by ice-boyfrom free stuff,(and pants, but thats another time) http://www.renderosity.com/mod/freestuff/?item_id=60835
we are gonna fit this t shirt, on my 4 foot 9 weight mapped v4
shes already wearing dynamics fitted by the method we are gonna try here. the socks were at one point conforming tights, i left them on to show what i believe in certain cases is the advantage of dynamic over conforming.
this method is not useful for animation, but great for still images. lets call it shrink fitting.
2)go to frame one, go to the joint editor and go to the bottom and hit zero rotations. you want your frame one figure to have your figure morphs, in a zero position pose.
now we are going to scale down the Body. my sample figure is significantly smaller than average,so i set the body scales as Body 99 body x80 body z80 body y 100.
this is key as your figure is going to "grow into" the clothing. now do the same thing as you did in frame 30, go to the animation panel at the bottom right next to the key, and add frame 1 as a key frame. you should now have 2 keyframes.
3)ok, now still in frame 1 open your props and add ice-boys t-shirt, (its materials are in the mat zone folder, not the pose) it should look something crazy like this
parent it to the hip. Always parent dynamic cloth to the hip.
ok so its crazily big, but first lets make it a cloth object. go to the cloth room. find the thing that says new simulation
click it, call your simulation what you like, i called it ice-boy t.
for now just check the top and bottom boxes.
now it will ask object to clothify, select the shirt and click clothify
now we can go back and morph the shirt to fit a bit, nothing fancy, just closer than it is (note-if you morph an object before you clothify it, the morphs wont work after its cloth)
ok, so just using magnets ( select the shirt, go to object at top left , create magnet) shape the cloth to something that approximates the figure. it is totally important that skin does not come thru the cloth, much better to be too big than too small. spawn a morph or 2 for shape. again it doesn't have to be all that close.
once you have it looking generally ok, the image above is about how i have mine, with a tiny bit of slimming around the middle, we go back to the cloth room.
find the "collide against" button this is what your cloth will react to. first hit Universe at the top, to clear everything, and then go thru and select what you want it to impact on
for a tshirt it should be hip ab chest neck, the collars, maybe the shoulders, and the thighs. i have also set it to collide with the shorts my figure is wearing
you do NOT want to start draping at zero pose BTW, uncheck it.
the collision offset and depth are like the distance off the figure the cloth is. the socks are at about .150~.180 .300 is fine for a tshirt, if it seems too much or too little adjust it.
the ignore collision buttons are pretty self evident. if you want the hand to interact with the cloth, uncheck it, or select the hand parts. almost done
the default settings, as you see them here are fine to start.they approximate cotton.for something that clings like socks or a leotard etc, you would reduce the cloth density, to say .001 or even .0001 if you want it to seem wieghtless. air damping can also be switched off, it is the force of air on the cloth as it moves. if your frame 1 hip setting puts it up in the air, and your frame 30 is on the ground, air damping will make your cloth t shirt or skirt look like a parachute.
ok, unless i have forgotten something crucial, you should be able to hit "calculate simulation" now. there might be some crazy looking moments between 1 and 30, but it should be ok
this is how it turned out.
a few things to keep in mind. if you want it to fit tighter, either make the cloth closer to your figure when shaping it, or decrease your frame one body X & Z scales even more, like 70 etc. making it looser just go the oposite.
dynamic cloth generally works better with higher poly counts, it allows for more natural movements and flow. I hope this was useful. if it was i can update some time in the next couple days with pants and skirt techniques which are slightly different.overall i have found that for any figure that is very difficult to shape conforming clothing for, making and using dynamic is a great solution. alot of the conforming cloth will work as dynamic fairly easily. the only drawback is it sometimes has a lower polycount, and its polygons are often shaped for the figure it was made for, the advantage is, its often easier to shape closer to your figure using dials before you export it as an object.
also, i am in no way an expert, if anyone has different, or better info, please go ahead.this was just specifically targeted to this project, and getting a feel for the cloth room.
