background elements do not count nor register - i think you are done.  And again the wording is strange.  because it leaves us guessing with trying to get the last comment to pass.  but it never will.  The template wants you to visually pass the test!

Try exporting - then you will know if you are good to go?  Is PTC hiring?  I think they need a trouble shoot writer in laymen terms.

Hey, thank you for the reply. I've tried scaling my VuMark a number of sizes but still no luck. I don't think the problem is the scale because as soon as I add more elements (to add up to 42) into the light and dark it works and everything states that they are passed. It's just not registering that I have background elements for some reason. Do you have any other suggestions? thank you

Hi - so I had the same problem.  Scale all of your elements up a little bit.  Vurforia's wording is strange.  When it says at least one element is off ... what it actually means is that all elements are off.   Scaling all the elements (bright and dark) fixed it for me, and I did add extra white elements to my background layer and it worked.

Hey thanks for the resoponse,

So I had a look at the VuMark Designer Guide and saw that I could hide elements in the VuMark-Background layer. I've tried doing this but when verifying my changes my guidelines still state that they have failed. Is there something i'm doing wrong here?

I've included a picture of how i've set the illustrator file up. The 6 white and black squares in the centre of the origin are the elements i've placed in the background layer (to make up to the 42 required).

Thank you.

Hello,

The number of elements required is tied to the type and length of data that you're wanting to encode. See section 2.4 of the VuMark Designer Guide for more details.
