UMA - Unity Multipurpose Avatar on the Asset Store!

I deleted the old folder, trying to get a clean starting point. I could not remove the old reference to the shades.

Created a new folder and started over this time ensuring that after the slot was created I then rename the slot and the overlay; the recipe has its own unique name.

I'm getting nowhere

 

Did you press the button that said "Add to global library (Recommended)"? If so, did any errors appear in the console?
If you open the global library window, and drop the item on the drop pad, does it work or give you an error?
Is there perhaps an error in the console?
Is it possible you are using Source Control, and it has marked the index file read only?
Its located here: Assets\UMA\InternalDataStore\InGame\Resources

The new Global Library window looks like this:

The drop pad is the one on the bottom left.

If none of those work, can you run the "file/Rebuild From Project"?

Edit: I would also try to repair the index if you have not done that already.

 

I opened an old project with the old UMA version.

Imported the asset store models and saved my .blend file into this project.

started over from scratch in this project.

In the end, I imported the .fbx model from blender into the project and used it to create the shades.

I had to scale 100%, but it seems to be working.

I renamed the slots, overlays and the recipe, but got the same results. However, if I take just the overlay and add it to the library that worked.

Going to try adding the torso

I tried this same approach with the new UMA version it did not work !

 

Can you answer my questions, and try the things I have suggested?

 

not sure if this is the right place to post this and I apologize if it isn't.
I need to render A LOT of animated people (over 1000) in a crowd.
I thought about mixing 3d models for the close ones and 2d animated sprites for far away ones.
Then I discovered this asset, so my question is:
Can I get away with merging the crowd into a few meshes and skinned mesh renderers to have nice performance and a slightly offset on animations?

 

please give me some time and I will document what I am doing in the old version that works first.

torso successfully added, but I'm still using the old version.

the shades actually, show in the correct place I'm amazed! I never got this to work before!

 

My old project with a converted UMA with clothing:

 

When I tried the "Add to global library" no errors, but the issue remains. If I try the pick option "its there" but still says cannot find.

I don't use "Source Control"

Where do I find the "file/Rebuild From Project"?

 

it's on option on the file menu, at the top of the Global Library window.

 

I just installed UMA 2.10.1 and unpacked HDRP-Races.asset.

But there is no HumanMaleHD/HumanFemalHD in the active race list I could select.

Anything I can do here? I'm using Unity 2020.2.a19 and HDRP 8.1.0.

 

I haven't looked at that in awhile, but did you add the folder to the global library?

 

that worked

 

New issue: The mesh hider is coming in the wrong way around

https://ibb.co/y0p3HDT

The feet are the same.

Is there a different way to hide these elements?

 

Sometimes the system gets confused about the orientations of the meshes. You can adjust the rotations on the panel in the inspector to make them line up. Usually, things are either 90 or 180 degrees off in one of the axis.

 

Pleased to say all working now

 

I have been trying to improve on my weight painting on the top esp in the neck area, but I am not seeing the changes reflect within the unity scene.

I also changed the poke through areas on the mesh and then not use a mesh hider at all. But again I am not seeing the changes reflect within the unity scene.

Now mind you I am simply updating the .fbx with no other changes.

Its like The UMA is always using the old version, whats the best approach when changing something?

I think a better approach when thinking about weight painting is "Not to use the unified UMA" if you think about this makes sense at least to me.

A separated head cannot possibly influence the shirt collar.

Currently, my shirt especially the collar is being affected each time I move the head, looks awful.

I don't mind starting over, but whats your advice?

 

I have issues with some of my helmets that appear fine when equipped, but when the character starts moving they glitch and appear/disappear. When player stops moving they appear fine. The animation turns the head left or right. Tried to replace the head slot but then the whole head is missing. any indications as to where to look?

 

The Unified model is only used when building slots. It's used as a "seams mesh" to know how to fix the normals.
The slots themselves contains all the mesh data.

So if you need to change the weight painting, you need to rebuild the slots from the base "split" models. The blender files are available on github in the content pack.

Personally, I agree on the neck/head weights. I've been considering splitting out a second bone for necks that only scale x/y for neck size.

 

Are the helmets UMA slots?

 

so I should be able to simply use the split version, the vertex groups are all the same. Just switch the armature that is used?

 

just wanted to check on this:

The Unified model is only used when building slots. It's used as a "seams mesh" to know how to fix the normals.

Can I use the separated base instead of the unified mesh and follow along with the tutorial?

 

The separated base won't fix the seams.

 

So the real answer is to use the unified mesh and do a better weight painting job.

In order to find what was causing my issue, I removed all the face vertex groups from the bodyguard's shirt. That solved the horrible pulling of the shirt around the collar, but I feel this is a dirty answer.

Will UMA be expecting to find these groups?

Now that I know which bones are really involved I could do a repaint and leave all the groups.

Whats your advice, please?

 

You should always use the unified mesh to make any modifications or to copy weights, and then resplit it to make new slots. This guarantees that you a) have a unified mesh to copy weights from correctly, and b) you don't introduce errors on the seam vertexes (different weights, different UV's, etc).

UMA doesn't use the vertex groups. Those are used by Blender to generate the vertex weights in the FBX. Those aren't used by UMA for anything either (beyond being copied to the resulting mesh). UMA DNA will only modify the bones.

If you strip the vertex group for the next off the collar, that will likely fix the twisting issue. But the result of that is that the collar will also not respond to the neck sizing. For the majority of cases that is perfectly fine. It's only if you allow an extremely large next to be generated will it become a problem.

 

Unity gives me a warning on the newly imported mesh with the vertex groups removed it's expecting them to be there.
I'll have to paint out the influence of all the facial bones, head and neck on the shirt.

Hoping there is an easy way to do this?

 

OK - yes, you have to have weightings. I thought you were only removing the "NeckAdjust" group. probably the simplest thing is to select the your mesh, go into the vertex groups.
Select "NeckAdjust" in the vertex groups, and delete it.
Then, Go into weight paint mode, select the "Spine1Adjust" vertex group. Then weight paint the collar with that.

 

Does anybody know if it would be possible to "detach" let's say a hand part (slot) from your UMA Avatar?
Let's say the player takes damage from an axe and we want the part associated with a slot to fly off or fall down etc.

Does UMA allow this detaching part to happen or is it a known limitation?

 

Yeah, kenamis made an addon for that:

https://github.com/kenamis/UMADismemberment

 

You need to do a little more than you have said, but here he is:

Give me a day or two and I will post what I did with photos.

 

To fix the collar I had to change some other weights.

So starting with Spine1Adjust I painted a small area with 1000 weight and 1000 strength.

https://ibb.co/TrxFZ71

That's the Red area within the shirt collar.

But you need to watch out for these areas as well.

1. mandibleAdjust
2. RightLowMaxilarAdjust
3. LeftLowMaxilarAdjust
4. HeadAdjust

The weight painting for the affected areas is changed to weight 0.006 Strength of 1.000

The NeckAdjust was not changed.

Oh in Blender and pose mode if you select the head bone and double-tap the "R" key. You can orbit the head around with your mouse.

 

Yes they are UMA slots

 

I would like to use Fuse models as my new UMA, The plan is to use the same process as with stealing the bodyguards clothing.
I spend a good deal of time within fuse reshaping the face, skin and other settings.

Is there a way to use the fuse textures on a UMA?

Example this face: https://ibb.co/F7xjZP2

 

You would need to rewrap the UMA models to use the new texture layout. If you're a advanced blender user, this should probably take a few hours. For me, it would probably take a few days. (lol).

 

If I'm understanding correctly, I think reprojection is the solution, and it only takes a couple minutes. You'll do this all the time, like when applying textures made for a high poly sculpted object to a low poly version for the game.

 

OK - a few things to check:

1. Make sure the "Max LOD" on the slot is still set to -1 (the default). Items can be dropped out by the system at different distances if you are using the UMASimpleLOD.

2. if you are using LOD, make sure you don't have an LOD slot that is "empty" being swapped in.

3. If you are not using LOD, and the hat is using a different UMAMaterial, it might be some sort of occlusion issue... you can put a UMARendererAsset on the character that has "dynamic occlusion" unchecked, and see if that helps.

 

Thanks. But what if I have more than one UMA in the game?
Like is there a special overlay slot that I can change swap between for face and skin?

 

Your post guided me well, so the issue were on some materials which had cutout as Rendering Mode, changing it to opaque worked perfectly

 

Reprojection is something you do in Blender to transfer the texture from one mesh to another mesh. In this case, transferring from the Fuse model to the UMA model.

You'd want to physically line up the head meshes so that lips match lips, eyes to eyes, ears to ears, etc. - it's a lot like matching clothing to the UMA model - and then you click on the original and then the target mesh, and bake. Blender then bakes the old texture to the new mesh, repositioning and resizing the original texture parts, making a new texture to match up with the new UV islands.

Once you've done that, you have a new UMA texture that you can use as an overlay on any UMA you make.

Does that answer your question? Depending on your particular art, needs, and workflow there could be additional issues to address. You might want to try this out for the first time in a very simplified manner, and play with it a bit so you get a clear idea of what's going on.

Kind of like when you first learn to make slots and overlays for UMA, there can be a bit of a learning curve, so you want to start out simple.

It can be a pretty fast, normal and easy thing to do once you have it down, and after you have a little experience, you'll get a better understanding of how and when to do it.

 

Thank you so much for your very clear reply. I am not too sure so going to ask, Do I need to split the fuse model into separate parts?
I think no!
edit that.
I should create a fuse race and also have a unified version.
Is this the correct wqorkflow if i want to use other clothes?

 

I can't give you a useful answer, most likely. You need to work on it, and doesn't Fuse shut down in a month or less?

One thing to keep in mind is that you normally need to avoid having texture issues at seams, like at the neck. So whatever you're doing, make sure you're okay in that regard.

 

Hi everyone, I have been implementing the UMA system to third-person cover shooter. So after a long time here he is:

I forgot to check his neck area especially as it shows through the shirt collar.

I'm pleased with my weight painting, look closely when he moves his head. The shirt collar remains unaffected.

impressive setpass calls

 

Hi,

I have another problem here with UMA 2.10.1 and Unity 2020.2.a19.

The slot builder is not creating any meshes. I tried different meshes and the builder always says it's a success but there is no mesh in the folder with the created overlay, recipe and slot.

Do you know what may cause that?

 

Hi, if my character only uses simple color and no textures. What should I do? Does my overlay and/or material needs textures? Because It looks like if I dont put textures on the overlay I have an error. Even if it put 0 in my material and overlay. I want to be able to change the color at runetime still, for the eyes, skin, facial hair and the hair.

Thanks

 

Try a white texture as a placeholder? Your material probably expects it.

 

Its exactly that, thanks brotha

 

Hi, can anyone explain me when the skeleton is getting added? I keep getting a NullReferenceException because my skeleton is not present at the time I want to access it.
So what I'm doing is:

Code (CSharp):

1. var recipe = "INSERT_A_VALID_RECIPE_HERE";
2. var id = "CHARACTER_ID";
3.  
4. var character = Instantiate(characterPrefab, transform.position, transform.rotation);
5. character.transform.parent = gameObject.transform;
6. var dynamicCharacterAvatar = character.GetComponent<DynamicCharacterAvatar>();
7. dynamicCharacterAvatar.LoadFromRecipeString(recipe);
8. dynamicCharacterAvatar.name = id;
9. dynamicCharacterAvatar.BuildCharacter();
10.  
11. var weapon = Instantiate(myWeaponPrefab);
12. var hand = dynamicCharacterAvatar.umaData.skeleton.GetBoneGameObject(UMASkeleton.StringToHash("RightHand")).transform;

At the last line the skeleton is null, later it will exist, so the question is how do I create a character and access the skeleton in one step? Or is there a way to force the skeleton to be created?

 

Use the Bone Builder. In the UMA menu

 

Perfect thanks JeffG, that was exactly the hint I needed. I copied the required/missing code out

 

Anyone know of a decent workflow for facial motion capture using UMA?

Given all the content that is being created for this tool, it's currently lacking an obvious way to integrate with existing facial animation tools on the asset store. Lip sync is easy enough to get working but, if you want high fidelity stuff, nobody seems to have discovered an obvious workflow.

There's the video of Anorak on YouTube testing out a workflow but it's not selling a particularly good end result, as impressive as it is so far given how this project is resourced and his constant investigative work.

Can bone-based animation produce the kind of results shown below?

I'm both excited and nervous as committing to any solution for the long term is an act of faith. UMA represents the best of what few tools/frameworks claim to do but this is the area where documentation/time saving on trial and error is needed.

The videos below show some existing solutions, how can we do something similar using the existing Unity environment and UMA (with all of its custom content/faces)?

and...

Lastly, the tool that Anorak used with some degree of success in 2018:
