Thread: LW needs a new Cloth simulation system...

  1. #1

    LW needs a new Cloth simulation system...

    Clothfx, while it may work seems to have problems.

    First it doesnt seem to be multithreaded, looking at cpu usage I only see about 20% being used
    Second, It seems to get progressively slower as it continues.
    Third, It wont abort unless I manage to hit it at just the right time, which is really annoying.

    Bullet is great, it is just not usable with rigged characters, so for cloth its not an option.

    If someone knows a way to use it with rigged characters, do tell...hehe.

    Is it CTRL?

    I remember that simulations are hard to stop: why the ESC key isn't the default for such things I'll never know.
    They only call it 'class warfare' when we fight back.

    It will never happen. Just buy Marvelous Designer. Incidentally, it's 50% off right now.


    My latest PF video on Marvelous Designer 8.

    Yep its CTRL..still have to machine gun it a little sometimes.

    Yeah, I have MD8..just hadnt considered it for animation. Ironically, I made the dress Im using in LW in MD..lol.

    Sim in marvelous and bring it back to lw either via mdd or alembic.

    Was just now playing with that. Will have to play with settings in MD to eliminate the times when the cloth slips inside the body..but its looking good.

    The fbx from LW loaded in just fine though.

    Is there an advantage of alembic over mdd?

    Can’t say in lw as I’ve only used it with modo but alembic is faster. Mdd is faster in lw from what I recall.

    I have been playing with Bullet Cloth Sim using a rigged character.
    The dress is not rigged, just the figure.
    The dress is a tight fitting short skirt style and using 500 um collision spacing on both figure and skirt is working pretty well to avoid poke through. The dress surface needs to be double sided.
    So far the remaining complication is gravity. Got to have gravity or when the skirt is raised by the figure raising a thigh it doesn't fall back down.
    But there can be a conflict with getting the linear stiffness just right, so that it both does not cause poke through and does not let gravity totally deform the dress.
    I'm thinking that using a much lower gravity force may do the trick.
    Something I've learned is that the dress needs to be one single geometry, because if it's made in pieces they tend to get pulled appart by the various forces.
    Limits the choices a lot though. I should probably try out Marvelous.
    Downloaded a trial but never tried it.
    I have not been able to get ClothFX to work at all. Don't know what's wrong but just gave up because bullet at least works.

    listen to HR ,cos they LW3DG atm have Hills to climb.

    M.D is the best works with Lightwave ,if you ask safarifx

    nicely then he may post his facebook tutorial. M.D. is seamless

    Yeah, looking like MD is the way to go at the moment..its fast, accurate and ez to use. At least until we get a better thing in LW...Plus in MD you have the choice of designing the clothing or even importing an obj to use as the cloth.

    I've used Bullet, syflex and now MD. No reason to use bullet or syflex after finding MD. Thing about MD is, if your cloth isn't simming right or is bunching up or stetching too much, you can adjust the cloth while its simming and correct it. You can add elastic, piping, zippers, buttons... you have tons of cloth presets that behave as each type of cloth would. You can also control the output of your mesh to be quads if you want, you get UVs... And when you're using marvelous, there is no weighting of parts of your cloth to move with your character, its all simulated and can even layer cloths on top of one another. There's also a wind controller if you want wind as part of your cloth sim. Marvelous has a ton of ways to control the look. Aside from maybe Houdini (which I would argue is less friendly to use and not as direct), don't know that there's a better cloth system out there outside of proprietary software.

    Indeed. Until now I just used it to make static clothing, but now getting the animation part of it down, its definately my go to for cloth sim, until something better comes along.

    The retopology is great too..yeah it's just linear cuts...but much better than the weird looks MD makes by default.
