FluX Dynamic

Hello everyone!
FluX Dynamic is a physical behavior control tool that enables the movement of "hair", "skirt", "tail", etc. in Unity.
You can adjust them with simple parameters while checking the moving area on the Unity editor.
FluX Dynamic has a unique design that does not use Physics to reduce the physics calculation process.
Therefore, it can be run on all platforms supported by Unity, from high-end to mobile.

[Features]
・Settings/adjustments can be completed in the editor (can also be controlled by scripts).
・The movable area is visualized in the editor, making it easy to set and adjust.
・A unique design that does not use physics, it reduces the physics calculation process.
・It can be used on a wide range of platforms, from high-end to mobile.
・Works on all platforms.
・All source code is included.

That look nice! But what’s the differences/benefits in compare with already existing solutions like Dynamic Bone or let’s say Boing Kit?

 

Hi pigglet,
Thank you for your question!

Comparing with others, FluX Dynamic includes a setting that takes into account "cloth" like skirts.

1. The skirt is designed to be linked to the animation movement without using collision,
so even if the character or animation moves at high speed,
the skirt will not interpenetrate the legs.

 

2. Multiple cloths (two or three cloths) can be controlled so that they do not stick out.

 

3. You can easily change the form of an object by inflating it.

 

4. Tails, hair, skirts, etc. can be controlled by AngleLimit parameter for each joint.

 

oh, I see! Yes, that's interesting!

 

Hello.I am interested in this asset.
Can this asset do multi-threaded physics control?I am expecting the performance to use very little CPU power for the main thread.

 

Hi ohbado,
Thank you for your question.
Unfortunately, this tool does not support multi-threaded calculations.
The calculations are done in the main thread.

 

Hi,
Does the mesh must have bones ? or everything can be set in the editor ...

 

Hi pietrina,
Thank you for your question.

FluX Dynamic is designed to control bones only.
The reason for this is that controlling Mesh
vertices will cause a processing load.
However, as per attached video, even if you don't have "FBX, Bone, Mesh",
you can create a bone in the Editor and move it with FluX Dynamic.

 

i encounter a error when adding this in a character prefab scene, any help would be appreciated.
Object reference not set to an instance.
How do i fix this error?

 

Hmm... I can't reproduce it here.
HangManager is attached to Hang, isn't it?
Hang is four letters with no spaces, right?
-----------------------------------
Is it possible to attach a project to support?
And version information for Unity.

Hello I managed to find the problem. However I ran into another one.

when I follow your video

just with setting up the skirt,

I get this error. my character skirt flips upwards.

 

Hi thegrailvr,
Thank you for your question.

>Hello I managed to find the problem.
First of all, I'm glad you were able to solve the problem.
-------------------------
I'm trying to identify a new problem.
Maybe using AngleLimit will cause problems?

 

the defualt is 0 but isnt setting it to 90 allowing it so the skirt can indeed flip to 90? would setting it to 0 mean the dress skirt cannot flip?

 

Hi thegrailvr,
Thank you for your question.

The size of AngleLimit is the number of joints.

 

<<<<< This was during model creation >>>>>
When using AngleLimit, the orientation of the bones in the model is very important.
The reason for this is that the AngleLimit is based on the orientation of the bones.

 

our character zyx direction is not the same as the plugin however, are we still able to set it up accordingly just that x,y,z settings may be differnt? or we must be the same?

 

It is not possible to set it accordingly.
Unfortunately.
The direction of the bones in the model must be the same.

The reason is that
If you use the editor to deal with

Extra calculations will be involved.
Complicated settings.

We believe that it is more wasteful to optimize the data side.

--------------------------------------------------
There are two things where the orientation of the bones in the model is important.
1.AngleLimit
2.LockingAxis
If you don't use these two, the direction of the bones in your model is not important.

 

can you explain what locking axis is? and is there a smaple video of what it does? is it what prevents the skirt from going through the leg/body?

 

Hi thegrailvr,
Thank you for your question.

What is LockingAxis?
LockingAxis is a function that allows you to rotate on only one axis.

It is not used for characters.
It's a feature you won't use very often.

 

>is it what prevents the skirt from going through the leg/body?
No, sir.
A sample video of LockingAxis will be uploaded soon.

 

LockingAxis video has been uploaded.

 

Hi. I got some questions.
1. Does your asset works ok with cloth which is attached to a ragdoll?
2. Can I pull the end of the chain?

 

Hi Kagyu,
Thank you for your question.

1.Answer
Yes, it will work. The one attached to the Ragdoll will work.
I will attach a video on Monday.

2.Answer
Unfortunately, you cannot.
The reason is that the calculation method is different.

The FluX string is calculated once from the root to the tip.
The calculation to pull the tip or center of the string is done by
You need to calculate from the root to the tip and from the tip to the root.
In this case, the amount of calculation increases.
In such a case, the amount of calculation increases, so we do not calculate the force back to the root.

 

Got it! Thanks for the reply!

 

Hi Kagyu,
This is a video of FluX applied to a ragdoll.
---------------------------------
In order to apply FluX to ragdolls,
you need to rewrite the code in one place.
LateUpdate -> FixedUpdate

 

Hello. Is it supports colliders?

 

Oh, i see.
Another question: can i set different limit angle for all bone axis?

 

Can it be used on animated character for breasts jiggle?

 

Hi zavidiy,
Thank you for your question.

The angle limit can be set in String units.

For example, suppose we have Strings A through F.
A,B,C,D,E,F... Each can be set to a different value.

 

Hi zavidiy,
Also, for the string, set the AngleLimit angle for each joint.

 

There is one thing to keep in mind when using the AngleLimit feature.

<<<<< This was during model creation >>>>>
When using AngleLimit, the orientation of the bones in the model is very important.
The reason for this is that the AngleLimit is based on the orientation of the bones.

The orientation of the bones.
A sample model and demo are included in the package.
I think it would be better if you take a look at it.

 

Yes, you can. You can use it.
---------------------------------
In that case.
parameters so that it returns to its original shape even after shaking.

 

I don't use collision for skirts.
---------------------------------
Just like in the demo video.
Hair and body etc.
Capsule
Plane
Sphere
supports colliders.

 

Thanks for answers! I think I bought it in the near future.

 

What is planned for the further development?

 

Hi, zavidiy
Thank you for your expectations.Still considering yet, but we hope to introduce more useful tools in the future!

 

i need this in 2d

 

The "skirt will not interpenetrate the legs" is very GREAT idea, and all demo are run very good,but when I try to port the "Pivot" setting to my model's shirt, it is Very difficult to understand about "AngleLimit" and "Offset", The document is in Japanese, and it is difficult to understand when I try to use translation software, I have spent two days but always fail, I fell very frustrated, hoping to improve, then I will give 5 stars. Thanks.

 

I don't have this asset, it just came up on notification.. I had read in another forum just a few days ago about a
Better online translator, maybe this will help better IDK .. GL >> https://www.deepl.com/translator

 

Hi Andy888888,
Thanks for the feedback!

> "AngleLimit" and "Offset", The document is in Japanese
>I have spent two days but always fail, I fell very frustrated,
>hoping to improve, then I will give 5 stars. Thanks.

Yes. I'll try to improve it.

 

Thank you for your reply, very much looking forward to it!
If possible, I hope that this function can be achieved only by specifying the bones of the legs, without the need for complicated setting of "AngleLimit" and "Offset"

 

Hi. Can I use skirt with separate from main character rig?

also, any tips about rigging dress for use with your asset? Just like in your demo fbx?

 

What is wrong with my Angle limit? I made directions on the bones just like on your skirt. The part of the dress goes in back direction

 

Hi letsgoodby123,
Thank you for your question.
I've been busy with work lately, so I'm late in answering.
----------------------------------
This one has a strange bend to it.
From the attached image of Unity, it looks like the axes are oriented correctly.
----------------------------------
I'm curious about the bones in the attached image of just the skirt,
which are pointing sideways.
Is this a blender image?
I don't know much about Blender.
However, I have never seen a bone turn sideways.
I am guessing that this is probably the cause.
----------------------------------
If you don't mind, could you please attach an FBX so I can
I will do a detailed investigation.

Hi!

We're considering using your product and was wondering if this would be advisable to use on low end android mobile devices?
At most, we would have 16 characters all with flux dynamics (Example each character would have long hair and a skirt both with flux dynamics).

Thank you! It looks great btw!

 

Hi salandananjm,
Thank you for your question.
I've been busy with work lately, so I'm late in answering.
------------------------------------------
FluX is designed with mobile devices in mind.
I displayed 16 characters.
This character has a lot of shaking parts.
It runs at 60pfs on the latest Android devices.
------------------------------------------
On a low spec device, it is designed to run at
least 15fps without any calculation failure.
