    we are students working on a AR application. We use Augmented Reality plugin for UE4 and we are on the demo version (composed by blueprint on windows). We have an error while launching the ap on the phone which is "webcam init error". Is it because we are in a demo version? Or a wrong option on blueprint? we try to change to portrait the device orientation settings in init blueprint. Thank you.

    Nice job !

    This is because you are using the demo version.
    The demo version only works in the editor for building it you need a license.

      AR version of the Matinee fight scene demo.:


      Interaction DEMO video:




      Hi everyone,

      After working on this for quite some time, I wanted to show my first results.
      I am developing a C++ code plugin that adds AR capabilities to Unreal Engine 4.

      The videos below are featuring simple marker tracking examples based on the open source ARToolkit library. The DEMO can detect and track 2 markers at the same time.
      Currently it is just a "proof of concept" running on Windows and Android, but I hope to release it as a plugin soon!

      Inside UE4 editor on Windows:




      Running on Samsung S4 mini:



      Hope you like it!
      Hi! The Interaction DEMO video inside the rotation operation in the illusion of how to achieve.Can you provide the next idea? Thank you very much.

          I have a fix camera and a white area front that (The area size is almost 50 cm) and a red point (2 mm) for send a position to me.
          How much accuracy can i have ? Can i get 1 mm movement ?

              hi adam, i tried to get the mobile phone screen resolution a bit better, i tried 720,480. But the screen turns purple. Is that something familiar to you? i changed it the way you showed here (android)
              http://www.unreal4ar.com/mobile-video-resolutions/

              And another question, i have great porblems to get this on my phone. Sometimes the export goes well 10 times, but then suddenly it goes wrong. The export is a succes, but the app wont start. And once this happends, there is no way to get this starting again on my phone. (uninstall-install. phone on, phone off,.. etc) Sometimes resetten the whole phone can help it.

              best regards robert

                  Are you sure the resolution you set is supported by your device ? Can you please try something like 640x480 or 800x600 ?

                    Hello,

                    Try the simple demo, it has an example for tracking multiple markers.

                      thanks it works great right now. Seems again and again a problem with nexus phones. Tried it on a samsung and it looks very good.

                        Hey it works really good, also my own made nft markers. Now the final step,... Making new scenes on different markers. But man, your levelbp looks complicated. Whats the best practice to do this? Should i copy the bp and make new event ticks? I rather not do that, because too many of these ticks wont work on most phones. When i duplicate the one touch bp and make some other meshes inside, seems a good start. But the way the bp will show and hide i dont understand.

                          Is this a full implementation of ARToolKit, but in Unreal?
                          What I mean is, can I use all the features of ARToolKit with this plug-in? And are they all available in blueprints?

                            Black and White fiducial marker tracking, matrix markers, and NFT tracking are implemented for Windows / Mac / iOS / Android.

                            Check out the documentation for blueprint nodes:

                                For multiple NFT markers, just edit the level blueprint and check all of your markers visibility with the get marker node in the tick function. Once a markers is visible use it's vectors/rotations for tracking your camera or subject.
