Model Target fail to create Prefab

March 21, 2019 - 8:38am #1

Hi,

I've been working a lot for the last year with model targets (Without any issue) but i've encountered some with the new workflow.

I used the Model Target Generator (v8.1.8) to generate both singles targets and a trained dataset, but none of them are working within Unity. Each time I try to import it in Unity i have a "Failed to create prefab!" error and the supposedly created 3D model is a giant stretched plane.

I looked at some other posts here, thinking it was maybe compatibility issues with the versions, but none of my versions works (2018.3.0/3/5), even when people pointed them as good with the MTG version.

Is there any problem with theses versions or a step i'm missing ?

Thanks for your help.

Hello,

I can only further evaluate if I have the 3D model that you're importing into the MTG. Please attach to this thread, or DM me a link.

Hi,

With exactly the same configuration as yours it's still not working properly. I'm having the generated 3D model with unusual scale values (6e+14) and if put to 1, I get a correct model in shape but not in scale (capture of the model attached to the message) so I can't correctly position content around it.

The 3D model is exactly as in the attached image, and worked well with the older versions of model target (Haven't modified it since).

Hello,

I just tried a simple test to create an untrained Model Target with 8.1.8 Model Target Generator, and import it into Unity 2018.3.0f2 (Engine SDK 8.1.7). I didn't have any issues.

What version of Vuforia Engine SDK are you using? Can you provide an example of a 3D model that generates this error so I can try and reproduce?

Thanks,

I am also getting error "Failed to create prefab" when importing custom package generated using Model Target Generator (v8.1.8).

let me know if any one has work around or ways to resolve this issue.
