[RELEASED] Magica Cloth

Unfortunately there is currently no way to reconstruct the data while it is running.
The data must be created in advance.
However, this request has been received from many people, and we are looking for ways to improve it.

 

Hello.
To use MagicaCloth, you need to install the [Burst] [Jobs] package.
Follow the steps below to try importing the package.

https://magicasoft.jp/en/magica-cloth-install-2/

 

Thank you!

 

thank you very mush

 

instal bust job already

but eror

 

Hello.
The installed [Collections] package seems to be out of date.
[Collections] is automatically installed when you include the [Jobs] package and now looks like the image.



Therefore, try updating the [Jobs] package version to the latest 0.7.0.
If that doesn't work, try removing the [Jobs] [Collections] [Mathematics] package and installing the [Jobs] package again.

 

ok I can fix now( install is very hard why you can't make it easy

now I will try to setup project

 

We apologize for the trouble.
Currently, the [Jobs] [Collections] package is a preview version, so if there is an update, the function will be deleted or renamed, so an error like this will occur.
Unfortunately this is out of control here.
Therefore, we are always developing to match the latest package.
Once the [Jobs] [Collections] package is official, this shouldn't happen.

 

Thanks a lot)

 

Hi there!
Will you be doing blendshapes compatibility? And if so, when will it be released?

 

Hello.
Unfortunately, we still don't know how to merge the vertices of the blend shape into Magica Cloth.
Therefore, there are no plans to work at this time.
However, the policy may change if a solution is known in the future.

 

Hi. Having some strange problem after 1.8.3 update. Looks like when velocity equals zero, generated mesh disappear where simulation done.

Any suggestions? (tried to recreate components, rebuild magica components, and clear library folder (latest unity2020 and packages))

Even if i am bad programmer, have no ideas how can i break this with my code =/

Spoiler: youtube

And another one, can't reach jitter fix with updated version. I will be grateful for any help.

Hello.
We apologize for the inconvenience.
I watched the video.
First of all, I would like to investigate the problem of clothes disappearing.
Is it possible to turn off the Burst compiler and execute it as follows?



And is there any error message in the Console when the clothes disappear in this state?

 

Hello! I have a technical question about Magica Mesh Cloth. I know Magica Cloth uses Job System and Burst Compile. However when I check the Profiler, it shows that the job CollectLocalPositionNormalTangentJob3 always takes much time and almost 99% of the job runs in only one worker thread while other threads are in idle state. You can check the upload file.

In my production environment, CollectLocalPositionNormalTangentJob3 can take up to 4 ms to finish and 99% of it runs in one thread. This is too much load and main thread is waiting for it. I wonder if there is any way to improve this job's
parallelism.

Thanks a lot!

 

Hello.
CollectLocalPositionNormalTangentJob is the work of shaping the vertices of the mesh and is executed for each renderer.
Therefore, if there are three renderers, three jobs will run in parallel, but if there is one, it will be occupied like a profiler.

The reason for this design is that this implementation will result in faster speeds if there are multiple characters.
However, if there is only one renderer like this time, there is a problem that the job will be in a standby state due to the processing.

How many vertices are there in the mesh in question this time?
Also, what percentage of the vertices are required for cloth simulation?

 

Thanks for reply.

When you say renderer, it's Unity's SkinnedMeshRenderer right? I am simulating a short skirt. The mesh of skirt contains 18000 verts and 26404 tris (is this too much?). After reduction work, there are 360 verts and 642 tris. You can check the attached pictures for more details.

In my opinion, even if there is only one job, it still can run in serveral threads if the job is heavy. So if there is only one renderer, I thought it may run in multiple threads. Correct me if I am wrong.

Thanks!

 

Thank you for the detailed information.
Yes, the renderer is the Skinned Mesh Renderer.
There are certainly many 18000 vertices, but there is no problem with a PC.
The reason for asking this question is that graying (Invalid Point) for vertices that are not related to simulation, such as images, reduces the load.



However, I found that this was not possible with this skirt.
Certainly, in this case, it is much faster to distribute the processing by vertex.
In fact, we have already experimented with the process of parallelizing each vertex.
Therefore, if the number of meshes is less than the available threads, it seems better to automatically switch to parallel processing for each vertex.
I promise to test this implementation in the near future.
And if there seems to be no problem, I would like to update with a near version.
Please wait for a while until then.

 

OK, thanks!

 

how to make fixed point of cloth and whole cloth follow character animation?
when I turn on character animation, clothes deform on colliders, but still at the same place as it was before. Is there some rule to do that? I set up penetration parameter for colliders, but it doesn't solve a problem

 

Hi, I wanted to know if you were working on this improvement.

 

Hello.
I couldn't figure out the problem from the text.
Do you have an image or video that shows the situation?

 

Hello.
rest assured.
This process has already been tested and will be included in the future.
It will probably be updated in the near future.
However, I've been busy lately and haven't had much time to work.
Please give me some time.

 

Hi!
When I have two or three clothes on my character, they intersect and penetrate each other. How to make them lie on top of each other and reduce penetration? I use a different virtual deformer for each cloth. Could this be the reason for the intersections? Do I need to use one deformer for the whole outfit?
This is how it looks:

 

Thanks for the answer. The console is clean of course. Tried compilation off, everything goes the same.

Problem reproduces when colliders have "global" option turned on.

Spoiler: Please have a look:

00:00 Everything is fine (no global colliders)
00:39 Disappears with global collider option on, when i move model

 

Thank you for the image.
First of all, I'm sorry, Magica Cloth is not a very advanced cross simulation.
Designed for relatively casual games.
It is difficult to accurately simulate such body-fitting clothing.
This is for the following reasons:

(1) Currently does not support self-collision
(2) Does not support mesh collision
(3) Since speed is important, the number of simulation iterations is small.

I'm sorry to disappoint you.
However, it may be possible to avoid it to some extent now.
First of all, it is better to put together all the meshes required for one Virtual Deformer, instead of attaching a Virtual Deformer to each garment.
Then, increase the reduction and drop it into a relatively low polygon.
This can be found in the following MeshCloth documentation:

https://magicasoft.jp/en/meshclothskirtguide-2/

Then use the Clamp Position and Surface Penetration features to restrict movement.

https://magicasoft.jp/en/paramater-clamp-position-2/
https://magicasoft.jp/en/prevent-penetration-2/

I hope this explanation helps.

 

Thank you for the video.
It was very helpful.
This seems to be a bug in the global collider.
Let's test if we can reproduce the problem here.

Basically, it is recommended not to use Global Collider except for special reasons.
I don't think a global collider is necessary for this character, so can I remove the global check and operate it?
If you check the global check box, all cloth components and collision detection will be performed, so the performance will be worse.
Therefore, it is better to remove the global check.

 

Update: 1.8.4

v1.8.4 has been released on the Asset Store!
http://u3d.as/1Hzx

A preset button has been added.

We've also added some DynamicBone style presets.
DynamicBone-like movements can be easily set up with this preset.



Release Note:
Added: Added DynamicBone style presets.
Added: Added a button in the Parameter Inspector that allows you to set presets with a single click.
Improvement: MeshCloth performance has been improved in Unity 2019.4 and above.

Actually it's not a problem, i can set colliders on the fly.

What about my second question?

Do i need some special settings?

 

I was investigating now.
Apparently, I noticed that a collision detection calculation added in v1.8.0 is causing vibration.
We are currently testing for improvement.
This vibration is a problem and in some cases v1.8.5 may remove the problem calculation.
The strength of collision detection will be slightly reduced, but it may be unavoidable.
(Or it may be optional)

 

Hello.
I have one question.
Do you use Update () to move the characters in the video?
Or do you do it with FixedUpdate ()?
Currently, moving by FixedUpdate () is not officially supported and vibration will occur.

 

I've fixed two issues you pointed out and sent a fixed version to [InBox].
I would appreciate it if you could test it.
Thank you.

 

Hello,

I'm automating certain processes that copies available collider values into magica colliders, and I noticed that Magica capsule length is different than a normal capsule height.

Shouldn't length and height be the same for both colliders? And is there a reason why the length is constraint at -1 to 1?

 

Hello.
Oh, this is my mistake.
At the time of design, I intended to match it with Unity's capsule collider, but it seems that I made a mistake.
Half the length of Unity's capsule collider matches the length of Magica Capusul Collider.
Unfortunately, this setting cannot be modified as it has already been released and is used by various users.
The reason the length is clamped to 1 is because we have decided that a collider longer than that is unnecessary for the human body.
If you need a collider longer than 1m, manipulate the scale of that collider's Transform.
However, it must be on an even scale.

 

I see.
Also another thing on colliders, is it possible to add box collider? Or maybe a non-infinite variation of the plane collider (use case: multiple level grounds).

+1 on this.

Just want to add, this asset is great.

 

BoxCollider needs experimentation, but it can probably be added.
This is included in the roadmap, but it's still undecided when to work.
(Because a lot of work is currently being done)
Therefore, it will take a little longer.

 

Yes, Here is demonstration. The fabric follows the body, but the fixed point is in the same place)

 

Hello, I have also met the same problem. I am very upset about the interweaving of costumes and ornaments on the characters.
Do you have a plan to increase the self-collision function of clothing?

 

Hello.
I watched the video.
Could you give me an image of the Virtual Deformer settings and vertex paint condition applied to these pants?
The following image is a sample.

 

Hello.
There are plans to implement self-collision.
I have that as my biggest goal.
I've already tested it, but I'm still not happy with the results.
Recently, I have been busy and have to deal with problems, so the work has not progressed.
So it will take some time, but I definitely want to implement it.

 

Yes, this is it)

 

Thank you for the image.
First of all, regarding the fixed point problem, try adjusting the following items.

-Max Weight Count-
Try setting the Virtual Deformer Max Weight Count to 4 instead of 3.
This count is the number of skinning bones at one vertex.
* Please do not forget to [Create].

Also, I would like to confirm, do these pants follow the body without clipping in the absence of Magica Cloth?

 

I increase Weight Count to 4, but clothes still don't follow the body movements.
About the question: In some places cloth has clipping, but it follows all body movements until I turn on Magica Mesh Cloth.

 

Thank you for your answer.
First, there seems to be a problem that the skinning of Virtual Deformer deviates from the skinning of the actual mesh.
This seems to be noticeable in the mesh that adheres to the body like this time, and I will consider whether this point can be improved.

However, even if this problem is solved, MagicaCloth is still unsuitable for cloth-simulation of the mesh that adheres to the body, as I answered earlier.
Please understand this point.

Unfortunately, I'm currently busy, so I can't get enough development time.
At a later date, I'll investigate Virtual Deformer's skinning issues when I have time.

 

Okay, Thanks a lot for your answer!) It's helpful.

 

Hi hoshos!

One small question:

My character uses Final Ik with Grounder IK to handle feet iks (stepping on uneven surfaces etc), but Magica Cloth is jittering / vibrating when using grounder ik. I had the same issue with Dynamic bone, but it was solved by going to Script Execution Order and putting the Dynamic Bone scripts before the Final IK scripts.

In the case of Magica Cloth, moving the scripts in the Script Execution Order list is not fixing the issue. Any idea how to solve this?

I believe it only happens with MagicaBoneCloth with Collider Collision ON.

UPDATE: Okay I think I managed to fix it by putting physicsmanager before the rest of FinalIk scripts.

Hello.
I own FinalIK, but I didn't know that these problems would occur.
Is Grounder IK the Final IK (Grounder FBBIK) or the Unity Animator IK?

 

Grounder FFBIK.

 

Hi is there any way you can add Small thing like Search for host bone by Name coos i need for UMA cloths and all the time uma regenerate when i add new items is adds new set of bones i buy your asset if you can make something like that

i use that on
Dynamic Bone asset script your asset sounds like upgrade for me if you can do that [im not coder][plan using that for mmo game]

 

Thank you.
I have FinalIK and would like to experiment with this issue.
How can I use GrounderIK to reproduce the problem?

 

* Please point out any mistakes due to translation.
Hello.
Please forgive me for not knowing much about UMA.
Unfortunately Magica Cloth does not support runtime builds.
All MagicaCloth data must be built in the editor before running the game.
In the future, we plan to implement runtime builds for BoneCloth / BoneSpring, but it will still take some time.
