Here a new demo : tire deformation
I'll add it in next release.

 

@kalagaan, awesome!!!
Please, I have some questions:

1) will this new feature work with fast wheels/tires?
2) What about performance. How many cars with deformation tires can be set without affecting the performance?

Thanks in advance and sorry my ugly english

 

Thank you
This is not really a new feature, I did a new demo script which set up motion sensor on a wheel.
It use VertExmotion shader, so it won't impact CPU ( less than 0.01ms for this sample )
The script is really easy to customize for your own project.

 

I've added a flat/inflated slider

 

Does it work with daz human characters? I mean these characters have like a few materials on them 1 mesh a few materials ,and i think that the meshes are opened(eyes areas)

 

How hard will it be to implement a tire like that into something like Edy Vehicle Physics?

 

It works with any kind of geometry and with multi materials, look at the video tutorial :

- Add VertExmotion component
- Paint softbody parts with the tool
- Add motion sensor and set up parameters

 

I don't have Edy Vehicle Physics package, but the tire demo code is really simple :
- It scale down the collider radius if the tire is not inflated.
- It raycast the ground to set up sensor position and radius for the mesh deformation.
- Deformation is computed between 2 tire setup : m_tireOk and m_tireFlat.

So you can easily change the source code for any kind of collider.


Here the source:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using Kalagaan;
4. using UnityEngine.UI;

17.         public float m_sensorDeformation = .3f;
18.         public float m_sensorInflate = .08f;
19.     }
20.  
21.     public DeformationData m_tireOk = new DeformationData();
22.     public DeformationData m_tireFlat = new DeformationData();
23.  
24.     public float m_tireInflated = .5f;
25.  
26.     // Use this for initialization
27.     void Start () {
28.  
29.         m_sensor.transform.parent = null;
30.     }
31.  
32.     // Update is called once per frame
33.     void Update () {
34.  
35. //setup collider radius
36.         m_wheelCollider.radius = Mathf.Lerp( m_tireFlat.m_colliderRadius, m_tireOk.m_colliderRadius, m_tireInflated);
37.         m_sensor.m_params.inflate = Mathf.Lerp(m_tireFlat.m_sensorInflate, m_tireOk.m_sensorInflate, m_tireInflated);
38.  
39.         //raycast on the ground to setup deformation
40. RaycastHit[] hitInfo = Physics.RaycastAll(transform.position, Vector3.down, 10f);
41.      
42.  
43.         for(int i=0; i<hitInfo.Length; ++i)
44.         {
45.             if (hitInfo.collider != m_wheelCollider)//avoid self collision
46.             {
47.                 m_sensor.transform.position = hitInfo.point + m_offset;
48.                 m_sensor.m_params.translation.worldOffset.y = Mathf.Lerp(m_tireFlat.m_sensorDeformation, m_tireOk.m_sensorDeformation, m_tireInflated);
49.  
50.                 float f = (1f - (Vector3.Distance(m_wheelCollider.transform.position, hitInfo.point) - Mathf.Lerp(m_tireFlat.m_colliderRadius, m_tireOk.m_colliderRadius, m_tireInflated)) / m_offset.magnitude);
51.                 m_sensor.m_envelopRadius = Mathf.Lerp(m_tireFlat.m_sensorRadius, m_tireOk.m_sensorRadius, m_tireInflated) * f;
52.              
53.             }
54.  
55.  
56.         }
57.  
58.     }
59.  
60.     public void Inflate( Slider sld )
61.     {
62.         m_tireInflated = sld.value;

VertExmotion is used in the game Valley
comming soon!

when i try to paint the mesh either it does not paint at all or paints in the wrong places... I have multiple materials, all are set to be Vertax Emotion Standard. Its strange but it looks I can paint on invisible representation of much larger second mesh. I see a main mesh which i would like to paint and I see some kind of second larger mesh made of vertaxes

 

OK i solved it I had my mesh scaled to 1.7, when i changed it to 1 it works

 

Hi, what is your version of VertExmotion?
1.4.1 should fix this issue.

 

1.3.1 but I downloaded it like 3 days ago from unity

 

The latest version on the assetstore is 1.4.3, it require unity 5.3.2 or 5.4

 

well I dont know why but I am downloading version 1.31 from unity asset store all the time. I removed package from my temp directory to download it once agian from unity asset store but the same happens. versions 1.31 is being download

 

Are you downloading through the asset store website or the store built into the Unity Editor?

If you're downloading through the Editor, make sure you are logged into the store with the account that you bought the asset with.

If you aren't logged into the store you'll only be able to use assets that were previously downloaded and you won't be offered to pull down updates.

 

I've checked the vesion on the assetStore, it's ok 1.4.3
I think you're right, it should be a problem with the account.

 

I am loged in with correct account I checked dubble time


btw any plans for phong smoth tessalation?

 

@kalagaan,
I can confirm that the version I see on the asset store is 1.4.3.

Here's a screenshot from the browser version of the asset store:


And Here are two screenshots or the asset store built into the Unity Editor:



@pan.master,
If you are not seeing this version of VertExmotion in your browser or the Unity Editor, I would try logging out then log back in.

And if that does not help, you should contact Unity support.

What version of Unity are you using by the way?

My screenshots were taken with Unity 5.3.5p3.

I can't be sure but, since VertExmotion 1.4.3 was uploaded with Unity 5.3.2, if you are using an older version, you might not be able to download the latest update in the Editor.

 

Send me an email ( contact@kalagaan.com ) with the shader you need to convert
I'll update a version for unity 5.2 on the assetstore.

 

its 5.4 version of unity

 

Very very strange...
VertExmotion 1.3.1 cannot work on unity 5.4, because shader API has changed...
Only 1.4.3 can work if you've downloaded it with unity 5.4

 

¯\_(ツ)_/¯

@pan.master: you should contact someone on the Unity Asset Store team or email Unity Support.

 

well it works

 

ok, I get it!
the readme file is for compatibility between 1.2 and 1.3, this is not the release notes.
I'll delete it in the next release
You can check the VertExmotion version on the component in the inspector.

 

Hey Kalagaan, I sent you a shader a long time ago you said you'd try and help me with - haven't heard back. Anyway, just the thread to see if there was any mention. The shader I sent you had tessellation and phong smoothing (among other things). Should I send you a newer version?

 

When did you send your shader?
I always try to answer quickly to emails, maybe I didn't saw it...
Send it again

 

Sorry my mistake - I found the emails (Nov 2015). Probably I was too busy to try it out right away and forgot about it. I guess after everything in my project is updated to 5.4 I'll contact you about it again.

 

Ok
Shader API has changed for 5.4, so you'll have to download again VertExmotion from the assetstore, with unity editor 5.4.

 

Here the new presentation video

 

Is there a limit to the texture sizes that vertexmotion can work with? I upped my texture sizes to 4096 using unity 5.4.0 and I seem to be crashing every time I try to save my scene. This just started happening after I updated to the latest stable version of Unity. I was able to use vertex motion flawlessly in Unity 5.3 and had my character looking great with secondary motion but alas I am now crashing unity whenever I add the component.

Another issue that I seem to have run into (Without saving my scene) is that sometimes when I hit play, the areas on the mesh that I have painted to accept sensor params loose their painting and I have to redo it. So to work around this for now I have just used the Paint all option and defined the areas that I want to move with multiple sensors and guide joints. So I set up where I want the sensors to go on my model within Maya and reset the sensor position within Unity to snap them to their locations. Anyway i'm not sure if this is a bug or something I'm doing wrong.

My only guess is that my textures need to be smaller in size? idk... any clarification on this will help. Thank you for such an amazing and easy to use tool!

 

Hi, VertExmotion don't use textures, paint maps are used to store data into vertex color.
If you have upgraded your project from unity 5.3 to 5.4, VertExmotion won't work, because unity shader API has changed.
You have to download VertExmotion package again from the assetstore with unity 5.4.
All files will be updated

Edit : you can save paint data into a template, this will avoid the lose of paint informations.
You can also paint vertices with Maya : white for softbody -> black for static

 

Wow ok thank you so much. I believe that this is a preferred method for me to paint in maya first as it is very fast and I am familiar with this. I was able to get my scene to save without crashing with only 4 sensors :-/ this is after expected frustration and testing. Thank you for your help. I did in fact create a new project and import the vertexMotion asset separately into the project created in Unity 5.4. So I'm limited to 4 sensors on my character which is plenty to be honest. I simply wanted to see how far I could push the tool. Is this correct? Or should I seek to resolve the 4 sensor limit issue i'm having?

NM that last bit... seems that if I try to save the same scene it crashes so confused... I was able to save successfully the fist time but now I attempted to save a second time and bam! crash... any advice? again this was not happening with 5.3

 

Very very strange!
I need more infos :
- Any messages in the console?
- version of unity? 5.4.0f3 ?
- PC or MAC ?
You should not be limited to 4 sensors on a computer, this limit is applied on mobiles only.
Could you send me a sample at contact@kalagaan.com ?
I'll help you

 

Ok. I have gone through and done some tests myself.
I am using Unity 5.4.0f3
on a PC
No console messages warning of any errors.

Console reads:

I completely reinstalled Unity after removing all traces of it from my PC. Then I started a brand new project. I added the VertexMotion component to my character and setup my sensors. Then I saved and nervously waited... the save was successful but took noticeably longer to save after I added the VertexMotion Component. To test, I restarted Unity and re-loaded the scene. The scene loaded successfully. My save times had increased significantly when I have the VertexMotion Component on my character. I'm going to say that re-installing unity resolved the issue but will let you know if I run into this issue again. Currently sitting and waiting for my scene to finish saving after adding 2 more Sensors.

Thank you!

 

Thank you for your feedback

I did some tests on PC and MAC, all work as expected, no crash.
Your unity version was maybe corrupted...
I always change the folder when I install a new version of Unity, so I have all versions available on my computer for testing.

You should not wait more for saving the scene when there's a VertExmotion script.
Could you send me a test scene?

 

This is brutal. I would send you a test scene but I am unable to save any scenes with VertexMotion on my main character model. The scene seems to save successfully ONLY ONCE but after that any consecutive save attempts completely freeze Unity. When I check the task manager, I can see that Unity is working but after returning to my computer two hours later it is still frozen. My only solution is to end the task and start a new scene... I cannot for the life of me figure out why this is happening. I have the latest drivers from Nvidia, the latest version of unity. I reinstalled Unity completely on a new drive. I saved the scene the first time then attempted to save the scene again with a different name and that STILL caused Unity to hard lock. When I loaded my character.fbx into the scene view I noticed that all of the materials were marked Hidden/VertExmotion_editor. I had to manually switch all of them back to VertExmotion/ Standard, not sure if that has anything to do with what is happening. I'm completely confused on this... This must have something to do with version 5.4.0f3 of Unity as I was able to use Vertex motion without issue in Unity 5.3. I don't really know how to be more helpful but I wish that I could use this product to its fullest.

 

Wow!
Send me your scene without VertExmotion, I'll do the integration.
We will find a solution!

 

Here my new tool for Unity



http://forum.unity3d.com/threads/hair-designer-dynamic-hair-fur-tool.431393/

 

Vertex Motion looks great. Does it integrate with Alloy shaders? I need this to work with a Alloys Tessellation skin. Or if you have an alternative tesselated shader with subsurface scattering that works, please let me know!

 

VertExmotion is easy to integrate in other shaders, there's a section in the documentation, and the package include a conversion of more than 40 unity built'in shaders, including the standard shader.
I didn't do it for Alloys, but if you have issue, you can send me an email and I'll help you

 

Hey, i read the doc but im unable to make vertexmotion work with double sided shaders. Do u know if this is possible?

 

Hi, looks great - would it work for 2d? For example, 2d hair or feathers? Also, will it accept forces such as turbulence to create "blowing in the wind" type of animations for said hair or feathers?

 

I've got to admit, this asset is one of the best purchases I've made. Looking forward to using this in my project and also the Hair Designer. Keep up the good work!!

 

Hi,

I purchased VertexMotion from the Asset store today and am running into a strange issue. Whenever I try to paint vertices, there is a disconnect between where my mouse pointer is and where the brush circle is. You can see it in the screen I am attaching. I'm using Unity 5.4.1 on a Macbook Pro, if that matters.

Any ideas?

 

@alanmthomas I have had the same problem, but not with Vertexmotion. Not sure if it OSX problem (i got iMac), but solution for me is restart Unity / computer (can't remember as this has not happened for awhile). When this happens for me, everything is offsetted like 10cm, even the rightclick menu at hierarchy / project window.

 

@chelnok I tried the Unity restart, but not the whole computer. I'll give that a go and see if I have any luck. Thanks!

-- No luck with the restart of everything, computer included.

 

I just tested latest Vertexmotion in Unity 5.4.2f1 (osx 10.9.5) and everything works here. I tested SimpleMesh and Characters demo scenes.
