Hello,

 

after upgrade to Unity 2018.3 and Vuforia 8.1.7 RC textures from RenderTextureCamera are rendered "reddish". Screenshot attached. It's standard white paper with black ink print on it.

It occurs only on mobile devices (both Android and iOS), no problem when trying out in Untiy Editor. Had no troubles using older vuforia and Unity 2017.

 

Anyone facing similar problems?

Hello,

I am having the same issues with a red texture on Android (LG G4), but not on iOS (iPhone 6) and not in the Editor.

What I found out so far is that the following line is where the 'magic' happens:

Line 71 RegionCapture.cs:

VideoBackgroundTexure = BackgroundPlane.GetComponent<MeshRenderer>().material.mainTexture;

The Texture of the BackgroundPlane (containing the video feed) is shown correctly as background video, but when assigned / referenced to another Material it turns red. Does anyone have a clue why this might happen? An unsupported color format of the texture maybe? And if so, can it be converted?

The only possible solution I can imagine right now is not to use the BackgroundPlane texture in the RegionCapture script and instead reference our own WebCamTexture, but I have not tested that yet.

Also, even when the Video Background in the VuforiaConfiguration is disabled, a BackgroundPlane with the camera feed is attached to the ARCamera (just not fullscreen in the Editor) and the Video Background is still visible. Seems like a bug to me.

I apologize. I only asked because I saw some relevant references on older posts.

Anyway, on a Vuforia question, does the "freeze" feature works well on everyone? Changing the bool value on the "Freeze Enable" variable doesn't seem to make any difference on Unity 2018 with the latest Vuforia version.

Did anyone manage to get this to work with EasyAR in android?

I've tried using the "modified" unitypackage especially for EasyAR and put the RenderCamera with the RealityPlane in the appropriate slots but as soon as I compile and run to my android device I get a black background (not the camera feed) and the AR object appears without the camera capture material, just the material I have applied inside the Unity Editor.

I used Unity 2018.2.15.f1 and RegionCapture2.0.6_EasyAR.

For what it's worth it works kinda ok in the Editor since I understood I had to modify the marked parts in the RegionCapture.cs

I also have similar problem in unity 2018.3 .. :(

maybe anyone have solution?

Hi,

I'm having trouble updating unity to version 8.0.10 - the installer just seems to remove all reference of Vuforia from the editor.

Anyone had the same problem? I'm using unity 2018.2.21f1 via unity hub.

Any help would be much appreciated!

Thanks.

Same issue here..! Does someone fixed this??

Unity 2018.3.6f1 / Vuforia 8.0.10 / Region Capture 2.0.9

How did you manage to implement it in ARToolKit? Any instructions or source code perhaps? Thanks!

Same issue. RegionCapture is not wrapping on 3D objects properly

Unity 2018.3.6f1, Vuforia 8.0.10, Region Capture 2.0.9

But wraps properly on Unity 2018.2.20f1, Vuforia 6.2-10, Region Capture 1.8.0

This android problem is really frustrating :( 



Hope someone psots a fix for it here soon. Still not working.

Same issue here, working in editor but not in android device, any workaround?

Same issue with region capture not working with Android.

Unity 2018.2.5f1, Vuforia 8.0.10, Region Capture 2.0.9

Works on iOS and in Unity Editor, just not on Android devices.

Region capture no longer wrapping on 3D object correctly. (worked fine in earlier version of Unity and Vuforia)

Please fix this bug : " Vuforia "8.0.10". The AR coloring (REGION CAPTURE, GET-TEXTURE) works in editor but not in android.

I have same issue :(

Hi Maximrouf,



I adopted "Region_Capture" before and it works great.

https://github.com/maximrouf/RegionCapture.

But after i update my unity "2018.3.1" and vuforia "8.0.10". The AR coloring now works in editor but not in android. 

Could you please suggest how to solve it. Many many thanks. I am in urgent.

Hi maximrouf,

First of all, I would like to thank you for this amazing plugin !

BTW, I'm currently working on porting an app on Universal Windows Platform. Everything works find in Unity Editor, but not when I build as an appx, RegionCapture seems to return an empty texture.

Here is my configuration :

Unity version : 2018.2.6f1 (64bit)

Vuforia version : 7.2.23

RegionCapture version : 

Device name : MSI GS65

Device OS version : Windows 10 Pro

Orientation of the device : Landscape

Thanks !

Hello all,

I can run Region Capture, but the problem is Live Texuturing is not working properly. If I try to color the 3d model at bottom it colors slightly up from there. And also if I try to color at the top it colors bottom of the 3d model.

Please help as soon as possible. As I'm trying since so many days still not getting any solution.

Thanks in advance.

Hello maximrouf,

Your plugin is great as it looks.

But unfortunately live coloring is not working for me.

I'm using Unity 2018.2.1f1, Vuforia 7.5.20 and Region Capture 2.0.9.

I'm running it on iPhone 7 and iOS 12.1.

Want a help on this...

Thanks in advance if anyone could help.

Hi! Does this work with multiple image targets including ones that don't need region capture? It seems camera world center mode is defined by the first image... 

Hi @maximrouf,

I tried to edit the script for auto stop capturing after first tracking found,

I want to disable "Stop Capturing" button and change the trigger to script but it doesn't success.

Any example for that?

Thanks 

I fixed the issue by updating Unity and Vuforia.

Unity 2018.211f1 with Region Capture v2.0.9 and Vuforia V7.2.23

Best regards

Hi @maximrouf,

I'm using Unity 2018.2.2f with Region Capture v2.0.9 and Vuforia V7.1.35

I encountered an issue on iOS where the render camera seems to stop capturing after flipping the camera via Vuforia API:

        CameraDevice.Instance.Stop();

        CameraDevice.Instance.Deinit();

        bool result = CameraDevice.Instance.Init(newDirection);

        CameraDevice.Instance.Start();

        Debug.Log((result) ? "Successfully changed" : "Failed to change cam");

        VuforiaUnity.OnPause();

        VuforiaUnity.OnResume();

        return result;

Here are the steps:

1. Start camera (Default = back camera)

2. Scan image target, model appears with the region mapped as texture correctly.

3. Flip the camera (now = front camera)

4. Flip the camera again (now = back camera)

5. Scan image target, notice that the model appears to have a distorted texture.

In step 6, the texture that seems to be mapped is the last camera frame captured before the first camera flip happens. 

Any help will be appreciated.

Thanks.

Hi @maximrouf, @Pavan1607,

Do you have any work around on solving this issue? I'm facing the same problem on IOS Devices.

On iOS Region_Capture prefab is not aligned to the image target. It moves when the camera is moved .

Faced the issue on iPad pro and iPhone 7

Vuforia 7.0.36, Region Capture 2.0.9, Unity 2017.3.0f3

Any help will be appreciated.

SOLVED: 09/10/2017

Solved using Unity 2018.2.11f1 with Region Capture v2.0.9 and Vuforia V7.2.23

Hello,

I am using Unity 2017.3.0 and Region capture Ver. 2.0.9. The region capture is not working on the Vuforia version. I am trying to create a AR coloring page. Not able to find a few settings in Victoria as shown in the tutorial video. Does anyone have solution for this?

Thanks

Hello, 

I am using Unity 2017.3.0 and Region capture Ver. 2.0.9. 

I am facing a weird problem, when I am using my model, it is not getting live texture but when I use default models like cube and Sphere, I can see the live texture on them. 

Can anybody have solution for this. 

I am attaching screenshot for the reference. 

Thanks,

Vanshika 

Hi everyone,

I want to be able to save multiple textures and reapply them to my model when I reopen the app.

I already know how I can actually read in all the pixels of a texture and how it is encoded to PNG. And saved afterwards.

All of this can be achieved using the MakeScreen() function of RenderTextureCamera.cs class.

We know that the model is being fed this type of information when its texture gets changed live.

How can I feed the model this saved pixels information?

As everyone can guess, it does not have to be live when remodeling from a saved texture.

It can just be one function where it takes the saved pixels information and applies the info to the model.

Thanks!!!

Dear Maximrouf,

Thank you for your reply and support in here. I am trying to use the region capture in Unity, ( my software version:)

-Unity2017.3.1f1

-RegionCapture_2.0.9

-Window 10

I had a problem about the mapping display on the 3d model.  Since i had completed to arrange the mapping texture on the 3d model ( a rectangule shape with 6 faces) in 3dmax and i had export to FBX. Then the model is ok after import to Unity ( before attached with RC_get texture script, please refer to image "before script"jpg) but once i attached with the RC_get texture script, then the mapping on the model will be changed and not in the right position, please refer to image "after script" jpg).

May i know do you know how can i change/ adjust/ rescale texture on the model ? or is it any places can change the size of  texture image?

Hope anyone can share any solution.

Thank you for your attention.

Hello maximrouf;

I've been trying to use Region Capture but Unity complains about a missing Vuforia function (removed some versions ago):



`Vuforia.VuforiaUnity' does not contain a definition for `GetProjectionGL'

Is there a workaround? Thanks!

Hi Pavan1607 and Chinnuabhi..

I need time to check it. (5-7 days)

Stay tuned.

Regards, Maxim Rouf

Hello Maxim,

I am facing the same issue like chinnuabhi.

On iOS Region_Capture prefab is not aligned to the image target. It moves when the camera is moved .

Faced the issue on iPad pro and iPhone 7

Is there a solution for this???

Does this work only with image targets or also user defined targets

1. Unity version: 2017.3.0f3

2. Vuforia version: 7.0.36

3. RegionCapture version: 2.0.9

4. Device name: Apple iPhone 7 Plus

5. Device OS version: 11.2.6

6. Orientation of the device: landscape



I'm using Region Capture in my project which works fine on Android Devices but iOS devices are having some issues. Please refer screenshots below. 

Thanks in Advance.

Android Screenshot: https://ibb.co/fPdnQ7

iOS Screenshot: https://ibb.co/jGtyXn

A new version 2.0.8 was uploaded.

https://github.com/maximrouf/RegionCapture

That's new:

- Small fixes in code

- "RegionCapture" plane has an orange color in the Editor.

- Added Readme.txt

Thank you Maxim,

everything is OK...

Hi Pancar.

You need to set the "World Center Mode" in the ARCamera settings as "First_Target"

In the "Region_Capture_A" and "Region_Capture_B" GameObjects please check the "Flip texture Y"

Hi Maxim , i have a problem like as pedrohbalmeida's.

Im trying Get_Texture scene on android.

My gameobject scales like this;

ImageTarget 24.7

Region_Capture_A  1

Region_Capture_B  x 2.47 - y 1 -  z 1.729

Unity 2017.2.0f3  and RegionCapture_2.0.6

I uploaded my project, do you have any advise?



 

Wojjitas, I don't know. - Maybe your ImageTarget size much larger or smaller than the "RegionCapture" plane?

HI Maxim Rouf

I'm having a problem when i add R_C/Samples/GetTexture to my model ( which is a FBX from maxon ) 

I'm not getting region capture in the inspector/ GetTexture (Script) of the object. there is always render camera 

what i'm doing wrong ?

Hi maximrouf

in easyAR will it work with model having multiple mesh?

Lavan09 - You need to copy "RC_Get_Texture" from "My_model_A" GameObject (Right mouse button - Copy Component) and paste it on your "Cartoon Car1" GameObject (Right mouse button - Paste Component)

when i put my model its rendering in white color(material with unlit texture).

sorry.How did you mapped image target to my_Model_A gameObject??Where??

Hi Lavan09.  I don't know what wrong with your project.

You can try this unitypackage - https://drive.google.com/uc?id=1-8_fsyE8pKoK_0zPuoJRveJAlNCk5feo&export=download

i modified for easyar as you mentioned.still its not working.no error but i don't know where it goes wrong.
