    Yay! Download link is on thread first page.
    Until I manage to explain all features and how it works, you might get some headaches.
    bewaaaare with the bugs =D
    And don´t look to close on atlas code yet, it´s a mess :)

    hmmmm in theory i could make a default Toon morph for UMA in blender then Edit it in Unity

    this video may explain why i want a stylized look than a photorealistic look

    Wow this is so amazing.
    I am generally going for uber realistic. Ultra realistic. I don't care for uncanny.
    I wonder if it is possible to have the clothes be loose so we can use the physics cloth over it.
    I actually thought it could work in editor mode.

    The shader used in the the butterfly effect would be nice to use on this.

    Hi, Fernando. I'd like to thank you for releasing the beta as public, in the name of all the curious game developers here.
    I'm now downloading the beta with my slow connection. I'll post all my impressions when i test along this day, and post any good custom content i make.
    Now, i'm not eager to get UMA... I'm eager to see UMA getting better and better with time!!! :D :D :D :D :D

    I've been playing around with the prefabs, and I can see that meshed clothing has the same internal rig as the UMA, so that a change to the UMA adjustment bone must also be carried out on the same adjustment bone in the meshed clothing. So far, so good XD

    I cant see how the animations work when adding meshed clothing. There must be some method to link the meshed clothing with the UMA, so that animations affect the clothing too?

    Yep, it´s even going to be possible to sell your toon base mesh on Asset Store! :)

    Hey!

    This is not the one from butterfly effect, but gives nice results. I´m quite sure there will be people providing nice shaders for UMA on Asset Store.

    Its part of the skinned mesh paradigme. Since the bind poses of the cloth is linked with the same skeleton/transforms as the bind poses of the base characters it ends up working automagically.

    Now I can explain everything =D
    All is based on skinning, each vertex on the model is influenced by up to 4 bones. That same works for both clothes and body parts and as they share the same rig, merging them together is not a problem, they preserve the original link with the bones.

    This happens on UpdateUMAMesh()

    I´ll record a video explaining the code this weekend.

    Cheers =D

    Alright, I'll be making a skype beta channel. Its not a direct hotline to get help! Its more like a shared chat where everyone can share ideas, problems, etc. Anything that turns into a concrete idea should still be posted back into the forum! For now just pm me your skype name and I'll get you into the chat.

    exactly, just specific to one unity topic, rather than a catch all group. (I'm 10179 messages behind in the Grill :D)

    I found this one mesh/rigging bug when one element (the forearm) is larger than normal, it breaks the texture as the larger element moves over a smaller one (upper arm). The image is taken from the free gangnam dance from Mixamo. The UMA is a randomly generated one.

    $Image9.jpg

    There also seems to be a second bone in the upper arm; a bend where a bend shouldn't be :)

    Hi there!
    In this case you changed the forearm size separated from the rest of the arm? I won´t be able to support all possible individual bone adjusts to work isolated like that. I´ll take a look at the rig and skin to see if there´s a way to get better results on this specific case.

    On the second image, I might say the problem is the animation not having correct shoulder rotation data. It´s really hard to tell with just one image (in fact looks like the same problem is also visible on first image), but this is a common problem with mocap data. Are you getting better results with other meshes?

    I´ve been talking to Mecanim guys to see if there´s a way to handle that when importing the animation, interpolating with part of arm rotation itself.

    Thanks for the feedback! :)

    It looks like the actual transform limits are hard coded right now. Are those numbers generated from a set of models or are they just modified by hand until they look right?

    Well how to properly define those transforms are part of the scope of the beta. How to change the sliders into actual transforms. We're trying to define a set called HumanoidDNA which contains what you would typically set in a humanoid. That translates into some transforms. But that is a helper system to configure, serialize and share settings. Because talking about the raw transforms doesn't make sense. The actual system underneath doesn't have any limits, and I'm pretty sure you can set the HumanoidDNA to any value and the transforms will just follow.

    Yay =)

    I'm just rendering the video that will explain about that. I'm explaining most important areas of the code, and the video is almost 45 min long already, so I'm splitting it and editing in a way I can include more information.

    As I've explained on previews video, all body shape is simply changes on UMA bones.

    umaData.boneList["NeckAdjust"].boneTransform.localScale = new Vector3(
    Mathf.Clamp(1,0.6f,2),
    Mathf.Clamp(1 + (umaDna.neckThickness-0.5f)*0.80f ,0.5f,1.6f),
    Mathf.Clamp(1 + (umaDna.neckThickness-0.5f)*1.2f ,0.5f,1.6f) );

    Above code is simply converting a normalized neckThickness value into actual bone changes.
    The bone change itself could be done the way you prefer and the one that makes sense for your project.
    You could have extreme variations, include extra sliders, create and UMADna that carries extra values like wing size... all of this is possible.

    Cheers

    so u have some chapters done? if yes i suggest publish them becasue 45 min at once is too long - with available some chapters we can wait for next chapter and easily organize time for watching this ;)

    PM me if you want more details, but a high quality character designer along the lines of Daz3D or MakeHuman. I'm sure I'll have to build on top of UMA, but the more you do for me the better. ;)

    The waist / hip ratio is interesting because it doesn't seem to show up in character design software I've seen, but when they analyze scanned data from real people it's in the top 5 "primary components" of how body shapes vary - right after things like height, weight, and musculature.

    For anyone who's curious here are the morphs available in Daz3D and MakeHuman (may be out of date.)

    In this case, I would recommend Inheriting from UMADna instead of UMADnaHumanoid and creating as many sliders/adjusts you need.

    Hi there guys!
    I finally managed to spend some time on this case.
    At the left, I´ve adjusted the bone rotations to reach a more natural angle. It´s still the same rig and skin.
    The animation itself requires extra shoulder rotation, but at UMA side, I also managed to identify some adjusts I can include to better handle extreme poses. Right now, UMA avatar has no adjust on mecanim muscles setting, and this is very important for final version.
    Also, UMA rig already consider forearm twist, so I´ll include a script to get this benefit based on hand rotation.





    Ps. watching 50 UMA´s dancing Gangman style is really funny =DDD

    Just a reminder to everyone that we have a small but dedicated beta skype chat channel. And we're starting to experiment with new content.

    More people would be welcome. PM me with skype info for invite.

    UMA Overview
    A small diagram that I created for the beta group showing the relationship between the various parts of the UMA framework.


    We are still in need of more voices in the beta group.

    So pm me to get into our beta skype channel to make sure your workflows will be supported. Otherwise you may end up as this poor succubus.

    Will you guys keep informing us, who isn't in the beta skype channel, about updates and changes regarding the beta phase of UMA? Also providing us with the most recent beta build?

    Sure! For example, the rigging/skinning considerations started at the channel, but were then brought here. The same applies to the videos I´ve been posting here.
    All "long term" information I´ve been centering here.
    But notice that the Skype Channel is open to everyone, you just need to PM @UnLogick.
