Bug

What is the current behavior?

Custon NFT detected, but elements are not positioned on the marker.

If the current behavior is a bug, please provide the steps to reproduce.

  1. https://manyworlds.synology.me/manyworlds/development/war/arjs/index9.html
  2. (open the website inspector to see the console)
  3. Use this marker: https://manyworlds.synology.me/manyworlds/development/war/arjs/moon.jpeg; its a bit tough, I have to put it near the camera. --> This message is logged: [info] Tracked page 15809416 (max 0). --> My own log is logged: 'markerFound' --> Opening the A-frame inspector (ctrl+alt+i), you can see the entities in the a-nft component; this one is set as 'visible: true', but it doensn't follow the marker.

Please mention other relevant information such as the browser version, Operating System and Device Name

MacOs 12.1 Monterey

Google Chrome Chrome is up to date Version 100.0.4896.88 (Official Build) (x86_64) What is the expected behavior?

I expected to see a sphere on the marker.

If this is a feature request, what is motivation or use case for changing the behavior?

@ljDevelopment probably your nft marker has low dpi, to check the dpi of your marker you can use the FeatureSET-Display online tool. It is always recommended a dpi of 300 (or around it). If less rebuild your NFT markers with that dpi values.

Hi, Two points here:

  1. Image is tracked, but its entities are not shown. --> BUG

  2. NFTs are difficult to detect The image used is completely functional in 8thWall: https://manyworlds.synology.me/manyworlds/development/war/arjs/moon.jpeg https://manyworlds.synology.me/manyworlds/development/war/arjs/moon.iset https://manyworlds.synology.me/manyworlds/development/war/arjs/moon.fset https://manyworlds.synology.me/manyworlds/development/war/arjs/moon.fset3

Also tried the T-Rex used as an example: https://manyworlds.synology.me/manyworlds/development/war/arjs/trex.jpeg https://manyworlds.synology.me/manyworlds/development/war/arjs/trex.iset https://manyworlds.synology.me/manyworlds/development/war/arjs/trex.fset https://manyworlds.synology.me/manyworlds/development/war/arjs/trex.fset3
