After more trial and error I've concluded that the issue I'm having is due to the image format.

A jpg worked. I've saved png's out of photoshop with every possible setting I can and none of them seem to work. 

I'll have to download the database and test to see if it works. Would I be correct in making the assumption that white pixels vs transparent pixels shouldn't matter? I mean neither hold any useful information for Vuforia anyway.

Thanks!

Hi there, I'm getting the "try again later" error as well. I'm trying to upload a side image for a cylinder target (I don't need top or bottom).

I've followed the documentation and the tips in this thread. My image dimensions should match that which I entered for the cylinder dimensions (circumference : side).

In testing, I decided to try an image with a completely incorrect aspect ratio. When doing this, I get an error message stating that I need to fix the aspect ratio. So I can (hopefully) safely assume that my image dimensions are correct, given that I don't get the error when I try to use my desired image.

My image is PNG-24 at 428kb size, so it meets the size and type requirements. Again, I tested unsupported size and type and got appropriate error messages explaining the issue.

Either the Vuforia backend is actually having trouble right now and I should try again later, or there's some other check that happens during upload that my image fails on and the error isn't being reported properly, instead it's being caught by this catch-all "try again later" message.

Thanks in advance for any help!

Me too facing the same problem...

Thank you. I sent you the files.

Yes, you can send me the files via PM.

Sure. I've done that a lot of times for work. Never was any problem. 

Anything else? 

Is it possible to send you the files? If yes, how long are you working - I'm in a meeting, can't send you the files right now.

Hi, you need to take care of image format (JPEG or PNG, RGB 24bits, no alpha, no 32bits, image size less than 2 MB), and

you need to take care that the Aspect ratio of each image is compliant with the aspect ratio of the various faces of the cuboid, as mentioned in this thread already.

One thing that can help is to sketch your cuboid on paper so to better visualize it and check the exact aspect ratio of each face, and then compare it with the one of your images.

Trying to upload since 7 hours. Need to finish the Target as soon as possible (->Deadline)

"An error occurred while uploading the image. Please try later."

My Target: Width 35 x 37 x 112 (cm)

Tryed everything. Just the top, right and front is working.

@ adala88,

the cuboid issue (top/bottom images) should be fixed in the current system; please try again if not alrready..

Hi attilanyers,

thanks for the images, I received them.

Actually in your case the dimensions that you are using for the cuboid are not respecting the aspect ratio of the images:

for example, your front image is 600 x 160 pixels => aspect ratio = 600 / 160 = 3.75

while your cuboid width and height are 71 x 19 => aspect ratio = 71 / 19 = 3.7368

So, you should either resize your image (with an image editor) so that its aspect ratio is 3.7368, or you should change your cuboid dimensions (for instance using Width = 71 and Height = 18.93 instead of 19.0)

You should also verify the length dimension (I only tested the width and the height using your front image)

Hi attilanyers,

could you PM me the images and the cuboid dimensions that you are using?

same error here

Hi adala88, just a quick update: we have identified the cause of the issue; this is under correction and an update of the TMS with this fix is expected relatively soon (although I don't have an official ETA yet, but i will update you when I have more details).

Hi, meanwhile, could you make some "experiments" by using cuboids of different sizes (e.g. changing width or height significantly), to see if you get it to work ?

This would help narrowing down the problem (while we also investigate on our side...)

I see ~  

really tks !!!!

Hi, I ave received your files thanks, and I reproduced the issue (also using a different image). 

On the other hand, I was able to upload top and bottom images (resized to different sizes) on a Cuboid with different dimensions.

So the issue does not seem to come from the image, but rather from the dimensions used.

I will bring this issue to the Vuforia team, as it might be some kind of misbehaviour of the Target Manager.

I will update you as soon as I get feedback. 

Could you PM me your image files and the cuboid settings (dimensions) that you use; I would like first to try and reproduce your error, so to exclude that there is a problem with your account...

thank you for the quick reply !!

yes  I've did that  like you said and I switch the other browser  to log in 

but I got the same error message  . . 

Hi, this might possibly be a temporary problem, have you tried logging out and loggin in again and uploading again ?

do you get the same error consistently ?
