This one works out of so many tutorials I tried, thx

[@MumtazKhan-yn3mb]

Well done! Thanks worked in one go!

How do i import an older ARfoundation version into Unity?

[@metekutlu90]

Hi Mohd, actually I would like to keep the 3D model in place even after the camera moves away from the tracked image. The prefab should not disappear. I would be soo grateful if you could give some directions ? Thank you very much !!

[@emii6199]

Watch this video for that kzbin.info/www/bejne/gaLdnXp3pbyDe6M I think it will help

[@onhathuy5056]

I have this error " Unrecognised Android chroma siting range: [2, 2]. Applying default" What should I do. Thank a lot!

[@mayank2564]

what should i do if i want to have multiple image target and multiple pre fabs to put on them?? please help me out with this one.

[@encereal]

Greetings! Thanks for the tutorial! Is there a way to keep the model stuck with the image once it is instantiated? Once the model apear; this one sometimes start to float around even if the image is still on sight

[@HairySeagull]

Did you ever fix this issue?

[@metekutlu90]

Thank you very much! What would be the logic to follow if we wanted to use the image as trigger to place and fix a prefab to a fixed position relative to the image ?

[@MohdHamza]

Glad you liked it. In regards to your question, you can create a sample plane or quad of the same size as the image specified( 0.1m in x and y in the video), then drag your prefab on it. You’ll get a good understanding of how to fix your prefab size accordingly.

how I wan to changes from that spider animation to my own 3D model from my pc?

[@DavonAllen92]

How would i do a simple can i see image yes or no enum system?

[@volgalgzkaradagoglu]

IDK why I am having black screen. Did I do something wrong with player settings for ios?

[@MohdHamza]

Hi, its mostly related to the combination of AR packages and Unity version, check my discord server(Link in description) . I have pinned few comments where people have faced similar issues and got it fixed.

[@b3armonk]

In case someone needs this, you just need to ensure ARCore is enabled under the XR plug in management. Then ensure you delete vulkan under the graphics API, and ensure you are running on ARM64 by changing the 'scripting backend' to IL2CPP.

[@starbuck3980]

I want to detect several images i just add more components of type Ar tracked image?

[@MohdHamza]

There is a multiple image option, but that requires writing a script so that spawning and deleing happens seamlessly between tracked images.

[@tarunrathore4513]

I have a problem that is when I remove AR marker but the 3d object still showing. So can you tell me what I can do.

[@MohdHamza]

Hi Tarun, For that a custom script would be added where AR Tracked Image manager is present. I haven't tried yet but do know what can be done. It would basically identify tracking states, if the marker isn't visible, the Tracking will switch to TrackingState.Limited, it is at this moment we would do something like prefab.setActive(false); You can read this article : docs.unity3d.com/Packages/com.unity.xr.arfoundation@4.0/manual/tracked-image-manager.html#determining-when-an-image-is-visible

Great video sir wanted to ask a quick question how do you replace main camera with AR camera for example turning my normal game to AR camera

[@akshatkumar2150]

Very good video every step was explained perfectly. I just have a problem when I run the app on my phone a black screen appears nothing happens what to do.

[@MohdHamza]

Thanks, check the pinned comments on my discord server(link in description), you might find a solution for your problem.

[@ajaysagar25]

Please Make one video of change the object color by script, rotate and scale by Slider or Button. Thanks

[@MohdHamza]

Sure will do that!

[@tathagatacreations9050]

Cool stuff like this type of AR

[@ujjwalsingh5188]

Hay ! Can you tell me how can i make a ar app that give camera's position (I means mobile camera co-ordinate) I search it on web but not able to find. Btw like your contant .

[@MohdHamza]

Hi, Thanks for liking the content. In regards to your question, I haven’t tried in AR but you can use Gyroscope and/or accelerometer classes to access the camera position and rotation.

[@ujjwalsingh5188]

@@MohdHamza yeah! I try it by gyro and accelerometer but it can only able to calculate orientation not position .

[@starbuck3980]

For ios is the same logic with the same components?

[@MohdHamza]

Should work with iOS

[@mikhailcherevatskiy5735]

It doesn't work on my phone. I just get the black screen. What could be the cause?

[@MohdHamza]

There could be multiple reasons. We have discussed and pinned a lot of them in my discord server. Check the invite link in the description.

[@SaurabhShelar-cm5xi]

Can I make it dynamic? Like I'll give user a ability to upload an image on server and they will use that image to track.

[@MohdHamza]

Well you can, but that will involve a bit of backend work to achieve that. Haven't tried it but looks possible.

[@nurfartinah4534]

Do we need to install google services AR in playstore while running this unity ? Because my phone cannot run unity itself & not even compatible to install that google services AR app

[@MohdHamza]

Check if your device is listed here: developers.google.com/ar/devices If it is you shouldn’t install any extra apps, your Unity AR app should work straight away.

[@wisdomkhan]

Not working. What to do?

[@macrowaves624]

Mine isnt tracking for some reason. the tracked image just disappears and reapears

why arfoundation 3.1.6 ?

[@amandixit8621]

I am unable to add AR session; it just doesn't appear when i click on XR. Please help

[@MohdHamza]

This sounds like the packages have not been imported, can you please check with your package manager if all AR packages are downloaded and imported.

[@amandixit8621]

All the packages have been installed and imported but there are errors in the console how can i fix them

Sorry how did it went from build and run from literaly running in another device?

Nice Video Mohd!! But I got a problem when I run my unity AR project my phone and laptop just show black screen. I have no idea how to fix this.... Do you know how to fix this. My unity version is 2022.1.20f1.

[@MohdHamza]

Thank you for your appreciation. If possibile try using using the same Unity version and package versions as I used. Apart from that black screen can be caused dur to a number of factors. If you go to my discord server, I have pinned thé solutions that have worked for others when they faced the black screen issue. Hopefully you’ll get a solution.

[@steveaustin6632]

Hi , Will the AR works if we take build as PC application ?

[@MohdHamza]

I think what you mean is Web XR which isn’t possible through this video. However what you asked for can be done as Unity has certain packages for WebXR.

Nice tutorial man👏, Just one doubt can we create live wine label app like 19crime wine with Arcore in unity? I have already made this with Vuforia sdk with cylinder as a target. But can it possible with ARcore? If yes, how?

[@MohdHamza]

Thanks Jay, In regards to your question, how I would go about doing the live label is to create a curved 2d panel in Blender (which would wrap around the bottle), use it as a video player in Unity. Create a logic that when you scan the picture on the bottle, it comes to life and play the video at the same place. It is definitely possible through ARCore. I've not used Vuforia for a while so can't really comment on that.
