# EZCloth Settings

• Okay, look out for Build 3. I'm exposing the U & V scale parameters. This either shrinks or expands the mesh during the sim (1 = no change) The effect seems to be applied very early on and large deviations from 1 (eg 2 or 0.5) import a lot of energy, I ran some tests with the hanging cloths but I need to run it on some real clothes to see how useful it is, but at the moment I am really excited!!!!

• Thanks for figuring this out!

• @wimvdb I just created a rudimentary ruched elasticated waist on shift dress! Let me play with this a bit more and I'll upload a new version, also want to test U & V fold and use edge springs

Is the U & V Scale a global setting for the simulation? I Or is it a setting per dynamic group?
If it is the latter case, it could be used to get better fittings for the chest area as well. And that would be very welcome!

• @amethystpendant
That is great news!
I understand it behaves similar to MD, so yes I can confirm scale variation should be done with care because the amount of energy introduced can be gigantic.
Consider an elastic band. If you pull that to twice its length, you can shoot it. Good if that is what you look for but will not always be what you want.

For those who ask what the difference is with geometry scaling:
Think of jeans with this u v layout, with the circumference of the legs in u- direction and the length of the legs in v-direction:

If you x- and z- scale these jeans to 90% of its original size, the centres of the legs would move closer to the x=0.0 plane.
If you u- scale it to 90% and simulate around the figure, the pant will shrink and become more skinny, vertical wrinkles will flatten.
This scaling is best understood as 'shrinkage'.

• One minor bug to report:
If you made a mistake and saved a preset before you created a sim, the resulting preset file can not be read and the next time ezcloth will generate an error. (this was the first time I used it before a preset file was generated).

And one request - Can you make the default parameters on start up the same one as are currently in the sim? Some dynamic cloth already has parameters set up. Or make a button to copy them from the sim.

• @wimvdb Thanks, I'll check that out, although I can't see why it would error just because you don't have a sim created but I can certainly try and recreate.

I think a Copy From Current button would be best as it currently defaults to the poser default.

• @wimvdb Build 3 is available with a "Copy Current" button and the U & V scale params

@F_Verbaas thanks for the explanation I'm playing with it and can see some really useful applications for this

• @amethystpendant
Build 3 works fine for me. Thanks for the addition of Copy Current!

The U Scale and V Scale are really nice additions as well. It really allows you to tighten certain parts of the cloth. That is a big help. Just create a new dynamic group and add the vertices you want to shrink to the dynamic group. Then use U scale on that dynamic group.

One other nice addition to the script would be to add the current actor in the EZCloth dialog box and - if possible - the current dynamic group name. If you have, you could also remove that warning dialog when applying the setings to the simulation.

• @wimvdb Thanks for the feedback. I'm sure I can loop in the current actor the same way @Snarlygribbly does in EZSkin, as I agree the extra dialogue is a nuisance.

The U & V scales and the stretch resistance splits means we are going to have to be aware of an actor's UV layout, in the past, as I tend to use procedural textures I haven't been that concerned about the layout, now I might have to revisit that for some of my creations. Hopefully tonight I will get to play with edge springs and possibly U & V fold resistance. Watch this space

• would it be possible to name the release zips 1,2,3 etc as currently when downloading all one gets is EZCloth.zip and that makes it hard to ascertain which actual file is the latest, I'm only making the point because not everyone is tech savvy enough to check the actual file date.

Hi,

My reason was that there would only be one Zip file so you always got the latest. But after this build I'll look at adding each version / build

EZCloth Build 4

I couldn't find that Use Edge Springs or Spring Resistance had any effect so I have removed those 2 params. I've added a read only text box indicating which actor is currently selected and removed the Dialog before applying the settings or copying from the settings as per @wimvdb's request.

I haven't had chance to look at the U & V fold resistance yet, hopefully tomorrow.

Thanks for that, all it really needs is the zip file to be renamed each time it is updated to reflect which version it is.

• Okay, I think I've ruled out the cloth Sim using differing values for U & V fold resistance, which is a shame. So I'm just about ready to release version 1.1.

Are there any other things people would like adding, e.g. Import Export settings so we can share. One other thing I thought about was a mesh density value, increase it and it would proportionally reduce density and increase shear and fold resistance.

Also I thought about adding a "Utilities" tab so I could have some of my cloth sim related scripts handy like copy figure to frame1 which copies the bodies x,y & z tran and rotation values to frame 1 which limits movement during a sim. Could also have a run simulation button that does exactly the same as the one in poser :)

Let me know what you think

Oh, one thing I have noticed, is that if you have differing U & V stretch rates things like skirts get nice lateral folds rather than just hanging like a sheet of paper, looks much more realistic.

• Thanks for the excellent work, first of all! This is much appreciated. As luck would have it, I've mainly been rendering dragons this week, and hence have had no call for cloth simulation. :)

Being able to share setting via import/export would be very useful.

Your position copying script automates something that I do manually, so that would be handy too.

While I'm all about take, take, take, is it possible for a 'run simulation' button to time the simulation, in the same way that D3D's render scripts do? I tried to put something together myself, when I wanted to evaluate the effects of various settings on simulation time, but I couldn't find a Python method that did what I wanted.

• Here is my wishlist.

• Yes, Import and Export of presets
• Ability to select the dynamic groups (with their settings) from within the script (now you have to do that in Poser and copy the current parameters)
• Run the simulation

Maybe i know a few more for tomorrow

• @englishbob Okay, dragons are cool too :o) I'll see about adding those tomorrow then upload the final version hopefully by the weekend.

@wimvdb I'm afraid you can't select the dynamic group programatically, it just isn't exposed in the API (unless I can work out a way to do it via commands and finding vertex groups in the current actor) Let me have a play.

If your dragon has bat-type wings, as most dragons have, simulation of the tissue could give perfect realism.

• IIRC Swidhelm, a vendor at Rendo, had a dragon for sale some years back that used dynamics on the wing membranes.

• Well, I've got the import working and the GUI sorted for the Export, just need to plumb in the export and start on the utilities, should have RC1 ready by tomorrow night all being well
