Augmented Reality for UE4

[Gosettiks]

Hi again, we purchased the commercial liscense two days ago. You mentioned in your last post; "I would suggest to use the 2D barcode markers, they are already implemented".
I can't find any implementation in the SampleProject. I only found the Marker Enumeration with 4 entrys.

Am I correct, it is implemented in C++ and I can access by Get Marker MATRIX ?

And how can I convert a bitmap file (tif, bmp, png ??) to this internal patt. binary file format ? Addig entrys into the list is no longer a problem of course. Thanks in advance...

Hi everyone,

Available on http://ar.uplugins.com !

If you need around 50 , I would suggest to use the 2D barcode markers, they are already implemented. You can download and print them from here: http://ar.uplugins.com/2d-barcode-markers/
If you want image markers I would not recommend to use more than 20 in the same app, as they take some time to load.

How many markers are possible at most ?. I would like to track a lot of static markers to only re-create camera movement, not object movement.

You can have multiple markers, but only 2D image markers are supported.

Is it possible to use small 3d printed models as marker? is it possible to have multiple markers?

Yes I am using the latest software.
I found that if I turn off the "Support bitcode in Shipping"
I can do the package

Hello Ivan,

I did some tests on both xCode 10.1 and on the latest 11 version and both worked fine with unreal 4.23 and the latest version of the plugin (v1.5)
I could not reproduce the issue with the compile errors in your logs.

Are you using the latest version (v1.5) of the plugin with 4.23 ?

Hi Adam

Hello,

Does the app run on an actual device ? If not, can you please send me the full crash log to info@uplugins.com ?

Thanks,
Adam

I got to package, but I aploaded my AR app to Google and it have an other error.

I made a test on Firebase
It is the result

You did the right way!
So is it loading, but not recognizing the NFT image, or do you get an error while loading ?

Can you show me the NFT image ? Not every image can be used as an NFT. It should have enough feature point to be tracked.

Hi AdamHorvath


For the Unreal project I need an NFT Marker created by me. I need 3 files right? .fset .fset3 .iset

Then I put then in the content folder in the ARtoolkit and then inside the DataNFT. Then I open MarkersNFT enum and add the name of the files but it doesnt work for me. I also changed the enum in the blueprint level.

I am working on version 4.23 of Unreal.


thank you all and sorry for my english.
