I have found a solution for my previous post

I was using the wrong condition for my branch action
e26c83279f74dfd4977a08a6fc94c8f2a49489ec.jpeg
then, to compensate the pause function error, i set the play rate to ‘0’

Editor continue crashes!

, I don’t know why but this time it could complete init but still crashes!!!

Hi ,
can I use this plugin as a qr code reader?
I need to scan some qr code to open the relative level, and I see it can be possible.
How can I open and close the (web) camera every time?
The project is made with UE 4.14 for mobile, Android and iOS (even if I need a Mac…)

Thanks for all

Hi,

You can only scan ARToolkit compatible markers, it’s not compatible with QR codes.

595

Is it your custom project or the sample levels included with the plugin ?

596

I started poking at AR (conceptual stage for now) before any reasonably priced AR HMD solution is out on the market and I am wondering if it’s possible to do object tracking with your plugin and UE4. Something similar to what Blender has been doing since 2011:

Also wondering if you have any near future plans to add support for Project Tango.

Hi , hi !

How do I make my 3D Model stay at his last known position when the marker is lost, and start tracking again when the marker comes back into view?
I’ve followed these steps :

  1. Open the level blueprint and locate the “set hidden in game node”
  2. Disconnect the new hidden pin and set it to false
  3. It won’t disappear if the marker is not visible.

But the 3d Model seems to get back to 0,0,0 and not the last know position when it last had seen the tracker.

How can I fix that?

Thanks in advance,

Denis

Hi ,
I think I can use a simple QR code inner the black frame, it’s correct?
//Anyway how can I open and close the camera every time?
Edit: I try the ARSample and I’m able to open and close camera and the marker recognition as I want!

Thanks for your reply

hi every one ,

any one know a step by step to create a custom marker ? i tried the ARToolKit tutorial and i’m completely lost :confused:

602

It’s my custom project

603

Hey guys, can anyone confirm if they’ve managed to use this with baked lighting? In the demo project, the method seems to be moving the meshes around to match the marker location, which doesn’t work unless the meshes are set to ‘movable’.

604

Wow oh wow

605

It works, but you need to move the camera not subject.

606

Sent you a mail with download instructions!

607

You can’t track objects with this plugin only markers, and images (NFT).

There is a free project tango plugin here: http://www.opaque.media/project-tango-plugin/

Hello Hello @ I asked my question 2 times but didn’t get any answer?
Is is because there is no way to do it?
