    The tool tips that pop up when you hover over the buttons are pretty good, that's where.i discovered the alt click reset simulation option.

    Yup, that's where I found it, too. However, it is only on the tool tip for the animated drape, not on the one for the static drape. But it works for both.

    Ah I just took it for red after reading it on the animated drape tool tip and that was an accident!!

    Animation is a real buggaboo.

    I did animated drape for clothing, great. Then I just wanted to go to the last frame and do a hair drape thing from that. ... I can't figure out how to get VWD to JUST look at the last frame, it keeps going to frame 0 (and then bugging when I give up and try dynamic hair drape)

    You need to do it in multiple steps. The cape will be in the scene (if send it back) as OLD_NAME_VWD. You start a new session and add both the character and the simulated cape as collision object (You need to rename the cape to get rid of the VWD, otherwise it won't show up). Then you add the hair as Hair object and go from there. At least that's what I did.

    No, even if I ignore the clothing, it just isn't working. I can't get a static drape from the last frame, and an animated drape throws out lots of errors in... French?

    Yes, the error messages are in French, the manual is in Frenglish... :)

    It works for me as long as I use the same draping mechanism, i.e. either dynamic or static. Here is an example with a tshirt draped over a skirt in two rounds of dynamic draping. I first fitted skirt using an animated drape. Then you use "send Animation to host". The VWD program exits at that time and you have the new animated object in DS. Now you start again using the figure and the freshly animated object (skirt in my case, don't forget to rename from _VWD) as collision objects and the tshirt as cloth object. You can repeat this cycle multiple times. Also worked with hair for me. Below is one frame of the result. The pockets of the skirt and shirt turned out to be unwelded and flew away. 

    If you want just one frame and use it in a static drape, simply export the draped model from the frame you want as obj ande re-import and then use that as one of the collision objects for the next static drape. That works, too.

    Thank you all for the details about VWD. I'll look into it. Do any of you have it yet?

    I've been beta testing it; it does take at least a little work, but the benefits are incredible.

  • nicsttnicstt Posts: 11,715

    You can do an animated drape; after it has finished, you can tweak indifidual frames (press the shift button). you can chose to return the whole series of frames, or just return one.

    If you duplicate node hierarchies in Daz, to duplicate the VWD object in daz, you can then return another frame, or the same one again if you tweak it some more.

    Returning the series of frames, closes VWD; returning individual frames does not.

    Thd: Maybe I'm having bad luck with the hair, but most of the efforts I've tried with it just fail, and I have no idea why.

    Can certainly be model related. I have had very wildly differing results and issues depending on the models I used. Which hair was it? If I have it, I can can chekc it out.

    So far I get some sort of address violation on Desideria hair, beach wave hair, GnLoveMeHair... basically, all long hairs.

    To quote myself here, that is what I see as the biggest hurdle for less experienced users (I have been using these kind of programs for over a decade) with this program:   There is very little consistency as to what parameters work or don't work for different pieces of cloth. One shirt might work great with defaults, another one just melts or flies away with the same settings. The parameters are very very sensitive to the mesh topology and density. Mind you, I have so far always been able to find settings that (mostly) work, but it can be a struggle. For me it clearly works best with clothes that are designed to be dynamic (no surprise).

    If I wasn't as experienced as I am, I'd probably have given up and asked for my money back. Although the same is pretty much true with the Optitex plugin, which has the added fun of way less informative tooltips.

    About what I expected.  This stuff is not easy to do right, especially at the levels of expectations of this demographic.  If it were easy, I would have released long ago.

    Well, to be honest, the problems stem more from documentation, UI, and stability, not, as far as I can tell, the underlying technology.

    Assuming you know what's going on and it doesn't crash, the results are fast and good.

    Like, for example, it was very easy for me to do a blouse with a fixed collar -- arrange the outfit so the collar fit just right, make the collar immobile, drape everything else. Easy.

    And I've had none of the constant 'omg the outfit is falling through my figure' problems I've had with other stuff.

    thd: I'm encountering 100% failure with G2F hair modeling. Can you verify if it's working for you?

     

  • thd777thd777 Posts: 945

    Oh, you are using G2F. I am just running a test with a long hair (Tatum) and G3F. That works fine here. I will test a G2F in a few minutes.

    TD

  • thd777thd777 Posts: 945

    Ok, I ran a trial with G2F (Belle) and Choko Hair. No problems. Here is a quick render. I didn't bother optimizing the hair parameters, hence the wet noodle look, but it works without errors.

    What is your exact workflow? Maybe we can figure it out?

    I'll try a simple figure with no morphs or pose, see if that's it.

     

    (I used to do QA so time to brush that off)

  • thd777thd777 Posts: 945

    My test was G2F with the Belle 6 shape using a dynamic drape between two poses.

    Oh hey, it's a wth bug. Same repro steps over and over and suddenly it's working fine.

    (I SUSPECT Dropbox might have been a factor -- I paused it's synching and, while the next two tests failed, it then started working a bit after that. And Dropbox was looking at the folders the script uses)

    Here is a quick illustration for one case where VWD can be an awesome asset: On the left is a character with conforming shirt (OOT long tshirt), and on the right I ran the shirt through a quick round of dynamics (static drape, includiong setup less than 5 minutes work). I think the setup improves greatly with the draped shirt.

    Yeah, I've been trying to push the envelope and it's been tricky. The usual problems with stuff not properly stuck together, although there are some intriguing mentions of 'glue' and sticking vertices together that might help.

    But if nothing else, being able to settle hems and sleeves of nearly every image will be a godsend.

    Also, while I don't render this sort of thing often, it totally nails a proper 'overly buxom bikini fit.'

    (only the top, the bottom doesn't use VWD... and could probably use it, really, if you look at how the string meanders over her stomach)

    Edit to add earlier, less cheesecake image... G3F with princess dress, a particularly difficult fit where I was able to try out 'nail to collision' (to keep stuff near the skin) and rigidity. Pretty pleased.

    Great render Tim! I'm guessing from your post and image that you can easily use VWD to get things like bikini top straps to look right, and not cling to the figure? If so, this may push me over the edge.

    Can you make elastic material in VWD?

    Yes, using the "Scale(%)" parameter, one can assign a selection of vertices a sort of shrinkage property which very nicely simulates elastics.

    Great to see we finally have company, isn't it?

    Still looking forward to yours when it is completed.

     

    thd777:

    Great examples, and beautiful work.

     

    timmins.william:

    Hang in there...  Some meshes might not play well right off the bat, and you might need to play with parameters to get what you are after.

    Regarding your first inquiry for a static hair drape on the last frame of an animated drape.  This can be done, but it is a little finicky.  Are you getting your scene reset to default while trying to load into VWD?

  • Oso3DOso3D Posts: 15,085

    Daremo: Yeah.

    Now, granted, it occurred to me that, in the specific thing I was trying, I could just do a static drape on frame0 and then move the hair to where I wanted later, since it wasn't interacting with much except the head (I was mainly trying to get some height and 'float' from hair that normally lays fairly flat, which is one of the cool possibilities -- need your character to be falling/swimming/in freefall?)
