Great, thank you for the help. Right now I've created a work-around where I'll use just one image-target rather than a lot of multitargets but I'll probably return to this in the future and then use correct proportions.

Thanks for the assets. I believe I've isolated the problem to the MultiTarget width, length and height. Here's what I did:

1. Opened "back-left.png" and noted down the dimensions (3776x832)
2. Created MultiTarget with W=832.0, H=832.0, L=3776.0
3. Uploaded 'back-left.png" to left side of new target

This worked and I was able to repeat with another different target, as well.

Looks like you've reached a default error message in our system. It should have indicated that you have an aspect ratio issue, but instead displayed invalid image. Please carefully review the aspect ratios of your target respective to the sizes of the images.

Good luck.

Yes unfortunately I'm still facing this error. I've tried some different resolutions but haven't figured out what's wrong yet.

Thanks. As you still facing the error and can't upload the image? Or was it a transient error?

Understood about the visual artifact with the 3D representation of MultiTargets. That is an artifact of the visualization implementation.

Hello,

Sure thing, it's just manually created noise-patterns only meant to be good tracking so nothing sensitive.

Sometimes I have gotten the error-message "An error occured while uploading the image. Please try later."

Another thing that's probably unrelated is that the biggest multitargets are bugged in the preview, they overfill the preview area and when you rotate the model it's sent to individual side upload.

Hello,

Can you please share all of the images for which the problem was observed? I'd like to recreate the workflow as part of an RCA.

If you do not feel comfortable providing them publicly, then please PM me the assets.

Thanks.
