3DT File error and ATG UI crash

[ghost]

Unable to open 3DT file generated with ATG or generate target: I am unable to generate a 3DT file for a specific property that is larger. (10.16.3 has not fixed this) When attempting to generate a file that does successfully open the 3DT file, the ATGs UI goes entirely white from top to bottom. No headers, labels, or images of any kind.

Observed problem: When opening the 3DT file generated by the matterpak, I receive a message saying the 3DT file is not compatible with this version (have tried with multiple different version from 10.10, 10.15, 10.16)

New to 10.16.3: When the 3DT file is opened for a different property, the entire ATG goes white when attempting to generate the target.

Expected result: The 3DT file is opened up in dollhouse view and the target can be generated.

Affected Vuforia Engine version: Incompatible 3DT: 10.10, 10.15, 10.16 White Screen Crash: 10.16.3

Affected platform:

• Workstation OS: Windows

Hello @elliotmarsico,

Would you be willing to share the 3DT file that is creating the problem? Having that will be important to our investigation.

Thank you.

3DT is an unsupported type in github so here is a link..

This is the file that is causing the "Unsupported 3DT File Issue in the ATG"

Here is the link to the other 3DT property that causes the white screen crash in 10.16.3:

I would also like to add that these matterport scans were taken with the Matterport Pro3 camera. These issues have start arrising since we started using this.

Unsure if it is related to the camera, outdoor scanning feature, or the bigger size of the files.

Hello @elliotmarsico,

Thank you for the artifact. I was able to successfully reproduce the "white screen" issue with ATG 10.16.3. I will open a ticket for investigation and provide relevant updates here.

We appreciate your patience in this matter.

Thanks, Vuforia Support

@ptc-ddowning I would like to post an update. We decided, to possibly work around the issue we are getting, to delete a number of the scans to make the file smaller. Now, we are able to generate the area target, but when importing the unity package into one of our projects, the property is imported without the mesh or any of the textures.

Here is the matterport link (should be public): https://my.matterport.com/show/?m=q7RVeUXgJbp

Vuforia ATG 10.16.3 & Vuforia Engine 10.16.3 were in use

This error message is displayed when attempting to import the generated target file.

@elliotmarsico thanks for the additional feedback. I have reverted it back to the team who is currently working on a fix.

[ptc-ddowning]

@elliotmarsico unfortunately, the fix for Windows ATG will not make it into our next release (SDK 10.17). A fix for MacOSX will be available in 10.17.

Additionally, we were unable to replicate the loading issue you recently posted. We were able to load it on a Windows machine using Engine 10.16.5 and Unity 2022.x. As the mesh has > 1000 textures, it does use quite a bit of resources.

[ghost]

Our project is currently Unity 2020.x which could be the issue.

Thank you for your help and responsiveness.

Update: The unity package works in Unity 2021.3.27f1

May want to note to future users that Unity 2020 is no longer compatible with the ATG .unitypackage files as of 10.16 (10.10 works properly for Unity 2020)

@elliotmarsico thanks for the update. Good to hear that worked.

We do provide guidance on compatibility - just may not be obvious to find.

As a fix was provided and the update to 2021.3 was successful, I am closing this issue. Feel free to open a new one in the future. Thank you!
