I'm new to the cloth room so please bear with me as I try to explain  :)

I've made a dress in hex and parented it to v4's chest in poser (poser 7.0.4.220) and run a simulation in the cloth room, but there are a few problems that i can see and not sure what ive done wrong,

I have collided the cloth to v4 in the highest heirachy, and the settings are as on the image, the dynamic controls and cloth control settings are the default (thought I'd start with the default first before learning further)

The problems i see are as follows

1. the back of the calf cuts through the cloth

2. the sleeves look crumpled with a wavy appearance on part

3. some bits on the skirt area show the facets of the model

Any ideas of how to correct these would be appreciated?

Thanks

What are the simulation settings? Check all three boxes. That normally works for me ;o). As for seeing the facets, that's pretty much common with dynamic quaded clothing. What is the current resolution of that dress? I'd consider smoothing it once more. Dynamics works better the higher the res. If smoothing sends it over 22,000 polys that might bog down your system a little bit ;o).

What I would try:

Turn the fold resistance down a little bit. Try 3.00. Turn the fabric density up to about 0.0100. The setting you have is a bit stiff. Rerun the sim and see what happens :o). One more thing...you can turn air damping off if you like. I don't like the "puffiness" it causes in a static pose like that ;o).

Another thing to consider: the more square your quads are, the better they behave. The quads in the skirt especially are getting rectangular.

Thanks Laurie

I only checked the last box in the sim settings, ill do it again with all three checked and your suggestion on the resistance/density, I did try to mess around yesterday on another dress but it sorta stetched and looked like stringy goo lol so thought it better i didnt try messing with the dynamic controls

I might try abit of a noise bump on the material to see if those squares disappear, (lol i can see this turning out as a furry dress)

I'll let you know how i get on  :)

I know it's a long thread, but this is a great thread to read :o):

http://www.renderosity.com/mod/forumpro/showthread.php?thread_id=2817155

I'm not insinuating that you're a dummy...lol. The thread is full of useful information ;o).

Laurie

Did you render with Smooth Polygons on? That might take away at least some of the facets :)

I can't remember trekkiegrrrl and my poser programme has now crashed and I can't get back in now, (typical)

I think it was off so will try with it on and see.

Thanks Laurie for the link, I'll check that out while I wait for poser to behave itself.

To get rid of the calve poke through you need an extra edge running up the dress to about the waist
on the sleeve edges I would make a seprate dynamic group to control the clumpyness
philc has some free cloth presets try them out

1. the back of the calf cuts through the cloth

Character skin can have displacememt map, or you need increase collision detection and offset. "Smooth polygons" in render setting can cause problem or resolve it ;)

1. the sleeves look crumpled with a wavy appearance on part

It must happend if facets have more then 3 vertex. Triangulate in modeling program or UV Mapper. (Pro)

1. Some bits on the skirt area show the facets of the model. It is terrible and visible even with fur material.

Open obj in UV Mapper.

Select all.

In "Tools" menu select "Normals" => "Smooth"

Since none of the calf should be showing, you can turn visibility to off for the body part.

Thanks all for your comments and remedies, I tried a few and these reduced the problems (smoothing, grouping, smoothing polygons which made it worse and changing settings) however looking at the link Laurie sent over, I have come to the conclusion that I need to take this learning curve abit slower, lol I thought it would be easier than it is. 

I really want to make dynamic clothes and give them out in freebies so it's not a case of make do and I need to get it right and I will have to start from scratch and learn a lot more.

I  think I  need to read that thread from start to finish (and make notes of anything I can find here and elsewhere) maybe a new year's resolution as it will probably take me the year to work it out. :/

Cheers to all and happy new year!

There's a lot of useful info and a couple of very handy tables on this page.

Cloth Room Tutorial

Thanks Replicant, that looks a good page as it has visuals on it and you can actually see what it means rather than trying to work out what its supposed to look like. :)

Perhaps I may add a bit.

Just from the image - I don't have details - I infer the dress is about 50 vertices circumference and 50 height, making a 50x50 = 2500 vertex object of about 1 mtr circumference and 1,5 mtr height. This makes squareroot( 2500/1,5 ) = 40 vertices per meter, or about 25mm vertex density.

Vicky, inside the dress, is about 1,80 mtr height, and consists of 70.000 vertices. That is 200 vertices per meter = 5mm vertex density.

Hence the figure has a much higher vertex density than the dress, which is the reason to check the "figure vertex against cloth polygon" collision checkbox and the reason why the second one (poly to poly) will not add much value - it is for about equal densities.

Quad-based objects of about 25mm density are known for the mild rubberish behavior, which might be reduced a bit by lower Fold resistance and will increase by increasing density, and will especially be reduced by pumping up the stretch damping to 0,1 or above. Note that parameters like density and the resistances show different cloth behavior when altering them in orders of maginitude, like halving, doubling, tenfolding and the like. Personally I do not believe that much in the effects of minor teaks.

Please do not switch off air damping, it's the only force that can stop the dress from swaying sideways forever.

Quad based objects are known to show behavior that varies a lot with vertex density. Lower densities are less elastic and might even freeze up. This makes me worry about the sleeve ends, the chest portion and the skirt in the circumferential direction. It implies that portions of the dress will behave quite different from other parts.

Changing quads into tri-polies makes the cloth less rubberish and more towel / linen like, thinner and (far) more elastic along the diagonals. For the quality velvet-like dress you seem you create. my personal preference would still be quads.

Success

Cheers to all and happy new year!

Hi Lully,  happy new year to you too!  May all your dreams come true this year.

How's your dress coming along? 

thanks aRtbee for your input,

I must admit that alot (not all) of what you said went over my head, when folk start talking about math in poser it's like another language, I am however relieved that quads can be used in some circumstances as I havent got a programme to change them to tris and will try the sim using the "figure vertex against cloth polygon" bit checked,

i have since smoothed the garment down once doubling the circ and vertical vertex and also cut the sleeves off :) they were the main problem so to begin with I have simplified the outfit. lol  another thing i did was make the quads more square and less oblong and that has reduced the marking on the skirt ( i think?)

I can see this being a long process of trial and error for me to actually see what happens when "this dial" is spun plus I have the other thread to read up on,

Cheers !!

oh thanks patorak3d, think we crossed posts,

the dress is now short sleeved and smoothed abit more, i'm still experimenting with dials but it looks better :)  I wont be going at this like a bull in a china shop as i wont have any hair left by the end of the process, need to keep calm lol

Gotta picture?

not yet, pc keeps crashing (again) think i need to do a total reinstall at some point :/

Oops!  i think i crossed this time...does this mean we've criss crossed?

You're quite welcome.  And thank you for making this dress.

BTW...i'll have you know "bull in a china shop" is a clan trait of mine.  So if i ever get out of line with you just grab me by my ear and turn me on my side.

You should be able to do that in Blender (I know you can convert in the other direction), and it's free....

Can it make a margarita as well? j/k

"...I can see this being a long process of trial and error for me to actually see what happens when "this dial" is spun plus I have the other thread to read up on,"

Just a tip: start reading at the end, that's where I put the summaries and wrap up in. Same for my lengthy posts themselves. Or just ask, that's faster than trial and error. Or wait for the tutorial, which at least is more organized and has the Beginner / Intermediate / Advanced info separated. And some open issues sorted out.

lol i'll give blender a go as it's free but no margaritas as I'm tee total :)

I'm hoping to get it right sooner or later, the modelling is the simple part

 I find conforming stuff for V4.2 tricky, mavka is a godsend to conform clothes to but for some reason I struggle with tricky vicky, so thought the next option was dynamic. Also have downloaded that marvellous designer 2 demo (only have 10 days left on that one) but doubt i will purchase it for 100 bucks to make freebies with, then again never say never.  MD makes the garments with the the tri facets so is probably ideal for dynamic wear. plus you can see it hanging the right way there in the programme.

Thanks Artbee, will check it out

Well, 100 bucks is too much if it were strickly for freebies, but if you're the type that likes your renders to stand out from the norm, then I guess it might be worth it ;o). 700 bucks to do commercial tho, is quite a bit out of my league...lol.

Laurie

lol i'll give blender a go as it's free but no margaritas as I'm tee total :)

i can respect that.  Speaking of which,  is it tea time on your side of the ocean?

Making conforming clothes for V4.2,  i think i'd rather be burnt at the stake than do it.

I seem to do less and less renders these days, think i tend to make stuff rather than create with it, most of my stuff over the last year (all bar the last couple of weeks or so) has been test renders.

maybe the price will come down when they realise a handful of people will get it at the price they ask. hopefully a sale one day :) 

yes it's tea time, 18.41 to be precise, although im only having toast as had a big lunch

Excellent!  OK...i got started thinking about food and got lost here.  Is Marvelous Designer 100 USD or 700USD?

both, plus another at nearly 1400 dollars, heres the link with prices, it all depends on the licence http://www.marvelousdesigner.com/Marvelous/Product.aspx

Personal license (which allows commercial renders and freebie mesh distribution, but not commercial mesh distribution) is $99 introductory price until February.

Commercial license is $699.

oh heck i just realised that means it will go up!!!!! need to make me mind up pretty darn quick then  :/

lol.i'm glad the women in my family control the money,  that way us men don't have to make decisions like that.

How's the picture coming along?

 im gonna shrink the dress down as its too big for her,

Lully...it's beautiful.

im gonna shrink the dress down as its too big for her,

Please leave the color the same though.

very nice :o)

Don't fiddle too much with poke thru...it's gonna happen in some spots no matter what you do. That's where the morph brush comes in really handy...pulls those right out ;o). Smooths crinkly folds too.

Laurie

i use default cloth collision settings and never get poke thru.

i think poke thru happens when the cloth in zero pose already is touching the figure(body,hands,feet,....). so make sure that in the first frame the cloth is not touching the figure.

the morph brush is perfect and fantastic for fixing cloth problems. i alot of times use the smooth for fixing folds.

By the image Lully showed of the original dress, the part getting poke was definitely not touching the figure yet ;o).

Laurie

here is a render i did last night, still testing but almost there,

Very nice :o)!

Laurie

Thanks Laurie, think i'm gonna put it for testing now, i did try and do a sitting pose but my poser is crashing once more

Thanks Laurie, think i'm gonna put it for testing now, i did try and do a sitting pose but my poser is crashing once more

Excellent.  What's causing your Poser to crash?

think it may be something to do with my nvidia card, the screen goes black then poser freezes up when the card recovers,

I know next to nothing when it comes to pc systems, the card is set on the adjust image settings with preview tab as  "let the 3d application decide" the PhysX GPU acceleration is enabled

not sure what else to do, :/

Hi Lully,  sorry for the late reply.  My mom asked me to tag along with her while she picked up her medications and bought a few groceries.

Anyhow,  have you talked with the people at nvidia.

Quote - Anyhow,  have you talked with the people at nvidia.

No, think i will check out the site to see if there are any tips.

Oh and I have sent you sitemail in reply to yours :)

Got it and thank you.

"I've made a dress in hex and parented it to v4's chest"

If you are using the cloth room, you shouldn't parent the cloth object to the figure.

That can cause problems.  The cloth room itself keeps the cloth object on the figure.

Sure you can parent the clothing to the figure. I normally parent to the body of the figure, but I haven't had any problems.

Laurie

i thought the parenting was just so that the dress moved with vicky etc if you were to move her around the scene.  Does it do anything to the actual dress in the sim?

If you're planning on giving your cloth mesh away then DO parent your mesh to the figure.

According to Poser 6 manual, always save cloth sim objects as smart props. That is, parent them. It also says to parent the objects to the hip as the hip is highest in the human figure heirarchy.

I use Poser cloth sims all the time:D They're my babies!

Thanks, I have been parenting it anyway and saving as a smart prop, think I do that as a matter of course due to all the smart props I've done, but I have been parenting to the whole body. 

Think I need to read up abit more and read the manual, lol I hate manuals (I the type of person to press a button and think "what does this do?"   :/   )
