Thread: VWD is saying my cloth item "does not exist" | Forum: Virtual World Dynamics

Could this be related to the name of the node/item? Maybe spaces, '&', or some other 'special' character(s) are causing an internal conflict?
Maybe rename your item and/or re-import it? (guessing here)

I think I found the problem and it is rather mundane! A "d'oh!" moment!
Turns out when I opened VWD I had the "weld duplicate vertices" box checked. Once I unticked that option, I was able to advance to the next step.
I knew it would be something simple, but I just couldn't put my finger on it!
Thanks for the advice!

Often you can fix it in Daz by selecting the item > parameters > mesh resolution > set to Base. Subdivision greatly increases an object's geometry so it can time out before VWD can import it. Returning to Base resolution helps avoid this timeout.
Thanks for your suggestions!
I am using Carrara, but I do not have the item subdivided. It's about 2000 polygons.

Hello MikeO,
This message appears when the time-out is reached during the importation. Generally, this message appears when the actor is hidden in the scene or if the actor is enormous and takes too much time to import. Please, tell me if this helps you to resolve your problem.
Thanks for the reply!
Hmm... My cloth item is about 2000 polygons and it is not hidden. I tried to import a new instance but the problem persists.
I just cannot find a reason for this item to be so troublesome!
I am using version 1.1.522.3630 with the Carrara Bridge.

Philemot-
After some investigation, I do believe the creases that appear in my coat_VWD generated model has something to do with my UV mapping seams.
It's an easy fix to smooth them out, as you know, but whether this impacts the simulation is another matter.
Hope this helps.

Can do, Philemot! And thanks for looking in!
Can you tell me a process by which I can send the file to you?
I can either keep the coat_VWD object in the file, or delete it to save on file size. I will keep the coat.obj I converted for Gerard, as well as the original coat, in the file. I'll also take out any unnecessary objects.
I'm not sure where the "merge vertices" checkbox would be. Is this a Carrara thing, or a VWD one?
I am using the dynamic simulation, and will be using this eventually for animation.
The model coat does not have creased edges, although the coat_VWD does end up with some, and I do smooth edges subsequently before rendering anything.
Curiously, some, but not all, of the creases in the VWD coat occur where I think I had assigned UV seams during the UV mapping process. So, where the sleeves attach to the body of the coat and the ones which would occur where the front and back sides of the coat would be seem to be where the creases are created in the process of importing into VWD. I've been adding geometry to the mesh since I last did the UV mapping, so those seams could have shifted, and may represent all of the creases that are appearing. I'll investigate to see if I can tell if this is the case.
I at least have arrived at an acceptable result, for now. I will eventually be turning to other files and characters and will see if similar simulations problems occur.
Thanks again! And hopefully my file will be instructive.
And also thanks for this wonderful plugin!!! You've breathed new life into Carrara! ?

And thanks again, Gerard (and Phillipe!) for this wonderful plugin! We Carrara users have waited so long for this ability!
Thread: Lumpy, wrinkled cloth results | Forum: Virtual World Dynamics
Hmm... after converting the coat to OBJ (as I was going to send it to Gerard for testing), I decided to try a sim with the new coat. Much better results!!! Still a bit of lumpiness but not nearly so much! ?
Here's what I can say that is different about the older and newer coats. With the older coat I was relying on using Carrara's "smoothing" tool within its modeller, to subdivide the mesh before sending to VWD, whereas the converted coat was imported without the need for using that smoothing. The resulting mesh (which was in effect subdivided in the conversion to OBJ) worked much nicer in VWD with minimal lumps.
The collision character has also been reliant on the smoothing to subdivide the mesh, but it doesn't seem to affect the simulation, as far as I can tell.
I still have to deal with a few poke-throughs and some areas where the inside of the coat poked through, but those are issues for another day..
Yay! ?
Thank you Smaker1 and Gerard for your attention while I tried to work this out!

Hello Gerard-
I did check and both objects have Stretch and Softness set at .1 and .01.
Next question, please. How can I send you the converted obj files? ?
Thread: Lumpy, wrinkled cloth results | Forum: Virtual World Dynamics
Hello Smaker1!
I have only tried other standard characters (Genesis) and clothes casually, and not as deeply. Many others have used VWD to spectacular effect with Carrara. so I wasn't as involved in studying those models.
But, it is an idea I shall explore so I can see if I get similar, or better results.
Thread: Lumpy, wrinkled cloth results | Forum: Virtual World Dynamics
Thanks for looking in on this Gerard!
I'd gladly send you the files, but, will these native Carrara files be of use to you? I can convert them to OBJs files, of course, but will that not change their natures? Unless you have and use Carrara yourself, that is. ?
When you say "two first default parameters", are you referring to the Collision distance in the Collision Parameters panel that opens upon first selection and before importation? Or something else?
Thread: Lumpy, wrinkled cloth results | Forum: Virtual World Dynamics
Hello Gerald! Hello again Smaker1!
I created both the character and the coat myself in Carrara. They were both fairly low resolution originally, so I've been trying different levels of smoothing and subdivision within the Carrara modeling app on both objects, as well as manually adding more geometry to the coat.
I have not used subdivision within VWD. I could not get it to work. That's when I started getting the "object not found" error messages. In fact, any level of subdivision or smoothing applied beyond a certain point would trigger that error message.
I'd offer to send you, Gerald, the files for testing, but they are created to be animated in Carrara only. ?
The solution seems to be almost there, and yet so far away!
Thank you both for your attention!
Thread: Lumpy, wrinkled cloth results | Forum: Virtual World Dynamics
Very nice, Smaker1! And you don't seem to have problems regarding the size of the mesh. Also, VWD didn't triangulate your mesh. I created my coat with quads and VWD triangulated it.
Here's my mesh post subdivided in Carrara.
Not too promising, I'm afraid. A smoothing applied doesn't help either.
But, you bring up the possibility that my character could be problematic, I'll take a look at that next.
Thanks again for your attention and aid!

Thread: Lumpy, wrinkled cloth results | Forum: Virtual World Dynamics
Carrara does have a subdivide tool and I did try it post simulation, but, it just produced a lot of smaller lumps. ?
But, after working on the coat mesh some more, I think I've found a good or better size for the mesh polys.
I especially worked on the lower half of the body of the coat, and less so as I moved up from there. And, as you can see, the lumps start appearing again as the mesh polys get larger.
So, thanks again Smaker1. You've put me on the right track, I hope.
