    Hey! It would be easier for me to show via video. Let me contact u directly.

    Hey Daniel, feel free to refer to this video:

    Hi Erica ,I follow the video step by step and this is the final result.

    I have to put some pins and stopped the simulation because the two pieces of fabrics continue to pass through each others.
    I also add a simil tattoo on the avatar skin, change the hair color and add lipstick :)

    wow! awesome! Thanks for sharing!
    If you find other ways of expressing the twist, please feel free to share!

    I want to share an image of the real prototype.
    the knot is what I was expecting to see in the simulation.
    Next time I'll try to drawn fold lines in order to help Clo to gather the fabric as it works in reality.

    Hi danielemanassero

    It looks like you got a pretty decent result, since this is a more advanced concept to try out in CLO! I know the loop is not as tight or as gathered as the physical sample, and it's difficult to move the twist ends without the collision forcing them to fall apart. 

    Maybe you can try these few tips in the future in order to build the garment so that is more accurate to real life:

     

    Add'l Thickness - Collision

    This concept isn't really in the video that Erica shared, but it's a pretty important tool to help with difficult construction and things like knots, twists, threading, etc. If you haven't encountered it before, Collision Thickness is an invisible buffer that surrounds the pattern pieces in the 3D Window. It's default at 2.5 mm, which means each pattern piece is pushing away from each other a total of 5 mm. If it's too low and you're trying to do something like tie a knot, the fabric pieces will just collide and melt through each other. So when you're in the middle of making a loop or you know the fabric is going to touch but you don't want it to, you can turn the Collision Thickness up high and the invisible buffer will make things more stable for you. I like to work at a 5~10 Collision Thickness when tying stuff and then when I've gotten my knot in place, I slowly turn it down while checking my simulation to make sure everything will settle nicely. In an usual workflow, I'll turn it down to 1.0 before I go to Render my garment just so it lies nicely on the body, but the value you use will depend on how complex your garment is and what will create the most stable simulation. This buffer exists because 3d objects aren't actually solid like in real life, so you do have to program it a bit yourself if you're working on something more complicated than a normal draped garment on the form. 

    Examples: 2.5 Collision Thickness versus 10 Collision Thickness (I have my 3D Style Lines on to better show the construction). 


    Use Elastic for gathering

    I made a test version of this garment to figure out what could help you, but of course my pattern is totally different from yours so the gathering is different, but before I started the knot I added an internal line and turned on its elastic so that I would have extra gathering in the center of the knot. Instead of making fold lines, this may be easier to work with. You can adjust the elastic ratio based on what your simulation looks like and since gathering also let me create a smaller knot, you can even use more than one elastic line to tighten it up.


     

    Tacking

    The last suggestion that might help is, if you find that your simulation is going wild and you just want more control, you can try the Tack function to secure parts of your knot. It's the same concept as making tacking stitches in real life.

    3D Toolbar > Edit Tack and Tack tools:

    It's a bit hard to see, but you can test it out too--below I've gotten my knot to a point where it looks good enough and I tacked all inside so I can make sure it won't slip out or try to move around while I work on other parts of my garment.

    I hope maybe one of these tips can help you with your future garment construction in CLO. Let me know if anything is confusing at all and good luck! You're definitely getting into the realm of more complex 3d manipulation now!

    Thank Ahn for your great and clear explanation of the concepts behind 3d simulation.
    I think the training time for people like me( I'm in fashion since 1982 as pattern maker) has to be more focused in these topics. We know how to make patterns and how to sew them together...in real word.
    Virtual world speaks a new language and we have to learn it in order to communicate correctly.

    I'll try to use your suggestions in my future jobs.

    "because 3d objects aren't actually solid like in real life"  this your statement make my think that in future they could be more "realistc"
    How about make the program recognize pieces as a perimetres family of triangles ad each triangle in a perimetre can pass through another "triangle family"? Somewhat like the layers concept.

    Hi danielemanassero

    Thank you for your feedback! It's really helpful to continually hear from knowledgeable garment people like yourself in order to make the tool more usable. I'm excited to hear that you're using new 3d concepts and applying it to your regular work.

    "How about make the program recognize pieces as a perimetres family of triangles ad each triangle in a perimetre can pass through another "triangle family"? Somewhat like the layers concept." ----- Do you mean being able to select a portion of the garment and pass it through another portion? Hmm...we actually might have a tool that does something similar, unless I'm not understanding what you are describing. Have you tried out the Select Mesh tool at all? It lets you select portions of your patterns in 2D or 3D and move just that portion (while Simulation is on or off). You could actually use this and try to do knots and such while still keeping in mind Particle Distance and Collision Thickness. 

    Link to how to use Select Mesh

    If I'm totally misunderstanding you, could you give me more info about what you mean by selecting families of triangles?

    Thanks!

    Hi Anh, I know the tool Select mesh, I also tried using it in the knot project, unsuccessfully.
    I want to say: all the mesh of a piece are inside a perimeter, so when I have a piece A and a piece B all the triangle could be called triangle A for piece A and triangle B for piece B.
    Now, it will be possible, one day, to order to the software that triangle A can't pass through triangle B and vice-versa? It could be very useful in a case like this project.
    Sorry Anh, I see now that I wrote "can" instead of "can't" in my first reply. My mistake.
    I never studied English at school. Forty years ago English wasn't so important.
    I'm trying to learn by myself using the online resources and with conversation exchange via Skype.
    Have a nice day.
    Daniele

    Don't worry Daniele! Your English is great and very informative--I get what you mean now by how it's similar to layering. I'm going to pass on your ideas to our development team. Thanks again for your feedback!

    Thank you Daniele Mannasero for the great tips. I'll give it a go.

    As an additional tip,  maybe once one has created a knot, save it as a 'garment' and simply sew/merge it onto another garment file that needs a similar knot. I have not actually tried this method just yet as I am trying to create a knot myself but it is something I thought about doing as soon as I have created a decent knot :).

    Perhaps someone is willing to share a 'ready-made knot' file for the community to use? That would be grand :)

    I am actually a little surprised there is not more file sharing of textiles and materials going on here in the community.

    Hey guys!!!!

    Let me share the file I used to create the tutorial video for the knot!! You can download it here. (The file is shared in CLO-SET which you can just sign-in with your CLO ID)




    Please click the DOWNLOAD button on the right top corner :)
