UE4 27 ARCORE IMAGE TUTORIAL

[@VVLGANESHK]

Great to see you're back.

[@ananthsundarraj924]

Hi to the guys who are making the same thing in UE5.0 set u r ndk 21.1.6 and at first time attempting to connect via USB comes in terminal open the app it will show error click ok and then again it will automatically launch and will work properly ..I tried till 21.15 and it works 🎉 ...i ll come back again after finishing the full project After some days:Wow cool this works perfectly fine for 5.0.3 the light estimation was top notch felt happy..thank you enrico.perfect one.Only problem is i cant see small text in your videos please zoom your screen and then record brother thats it thank you

[@EC_UnrealEngineTutorial]

thanks, for the contribution, .. but at least you don't use 4.27 because you feel forced, I suggest you go to the other tutorial in my channel, (the one for the ue5.0 version) which is perhaps more correct for version 5.. there have been some changes for the compilation between the two versions... and I also recommend reading in the description there are further helps.👍

hello, no the ones you see at 0.25 are mine, they have nothing to do with the tutorial, you just have to repeat the procedure I do.. you basically start with a new project in ar...

Great tutorial, worked very well. How complicated would it be to adapt your project to also work on iOS, would you know? Thank you.

it shouldn't vary much, but I don't have ios where to try ... but you can look here docs.unrealengine.com/4.27/en-US/SharingAndReleasing/XRDevelopment/AR/ARPlatforms/ARKit/

hlo sorry i have one more question widget works when i add to viewport in AR but when i add to actor, interaction doesnt work(i used widgget interaction component) so is it possible to interact in 3d?

[@EC_UnrealEngineTutorial]

I believe that by implementing the touch of this video kzbin.info/www/bejne/hXyZe4R5ecp4bbM (that of when you touch to go to a place) together with 3d widgets maybe it can work with..but you have to work on it a bit ..

Brother what changes in blueprint I should make to demonstrate using only one image and model for tracking

[@EC_UnrealEngineTutorial]

without making so many changes to the blueprint that would be a waste of time, just put a single image and a single object corresponding to it... :)

[@leong0123]

Do you think your method would work for Hololens? I'm working on Hololens applications and I do wanna implement image detection.

I can't tell you, not having tried it, but if it works with windows I don't think so, try to see this if it can help you www.geoweeknews.com/blogs/matterport-ar-mashups-microsoft-hololens-google-arcore-and-more

[@samphone92]

Greetings!! This is a fantastic update to your previous IMAGE tutorial :-) I have built my project based on your blueprint, and I am using both Animated and Non-Animated Skeletal meshes. It creates and awesome experience!!! I was wondering...... does the Image have to be Flat on a Surface, like a table for the ARModel to appear straight up and down as it should look? Or can the Blueprint be adjusted so that i can scan an Image on my PC screen, and the ARModel appears correct in the World Space that i am looking at on my phone?

[@EC_UnrealEngineTutorial]

hi, yes, you can scan images even on the screen, or even move them as long as you move them slowly, because they could lose tracking ..

[@samphone92]

@@EC_UnrealEngineTutorial Thank you......... I have been working on 1 variation where the 3D Model is Always upright, no matter the orientation of the Target Image, for example, your Chess Piece is always upright, in relation to the floor, or table......... Any ideas? I would like to put the Target image on a wall, any 3D Model i use for the experience, is still upright, in relation to the Floor where i am standing. I have tried changing the settings in the AR Session, (World Alignment & Session Type), but have not figured out how to have the 3D Model stay upright, regardless of the orientation of the Target Image. If you have any ideas of what i can try, please let me know.

Hi Enrico! I'm using your tutorial to spawn animated Skeletal Meshes, I'm having an issue though where two objects are being spawned from one tracked image. I've removed the other image as I'm only in need of one. Do you have any tips on how to disable the other one from spawning?

[@EC_UnrealEngineTutorial]

hi, your question is not very clear, you have to be precise, because you have to take into account that I have not seen your blueprints....but, I don't remember if on that tutorial, or on the others, but in the comments you will probably find what try, otherwise try to be more precise in the description, perhaps by sharing a video of your problem.

Then I managed to use your model to recognize images and create the models, but it causes a lot of conflict, it crashes a lot and even appears some arrows when the model crashes.
