Hello all,

With the launch of Model Targets and its restriction of only a single Model Target dataset being activated at a time, we have seen an increase in the number of questions related to loading and activating datasets programmatically.

Issue with Standard Model Target generation

Unity Editor
May 13, 2022 - 1:06pm #1

During generation of standard model target I am facing error code saying 'Model Target generation failed' without any explanation (screenshot in the attachments). I was trying another .obj and any types of 3d objects but no success at the end unfortunately.. It makes a lot of problems for me because I have to generate this specific model to import it and track in my application made in Unity. Could you please advise me what should I do in this case ? I have checked the same application on my friend's macOS system and it is working as expected but for me not which is suprising me.

Model Target generator display issue

March 14, 2022 - 12:29am #1


I am trying to use my GLB model as model target in "Model Target Generator 10.5.5" tool (under windows 10 OS). I can launch the tool, add the model but have difficulties to see it in the list and event more annoying I cannot open it to configure it so I cannot achieve the BDD training and use it in my Unity app.

Is there a configuration I can do (setting parameters in a config file or adding compatiblity features while launching) to fix that ?

I saw some older posts talking about something similar (but in 2019 I think), I hope you could help,

Topic solved

Hi everyone, 

Can someone tell me what files are included in the Model Target Database? 

I guess:

- authoringinfo.xml is for informational reasons for unity/ vuforia

- LokinkRaderv3.xml might be something for the Guide View????

- LokinkRaderv3.dat is the 3D Model for detection

 but what is this 193ecc5814.... in the Editor?


I need this information for my thesis- Thanks!

Model creator failed to create model

January 18, 2022 - 2:04pm #1

I have a scanned 3D model in obj format. I load it into the latest 10.3 Model creator and everything is all green lights across the top. I click created model target and I just get a pop up that says it failed. No more info and I can't find any logs.  However in my old 8.x version of model creator it creates the model just fine.  Any advice on where I could look to figure out this failure? 


I tried to attach my obj file but the forum says:
