I'm using the 6.1 SDK, and displaying two 3D models on an image target.
Everything works fine, except that sometimes not all the 3D models are loaded, and the onError callback of the corresponding model is fired with error:
"The .wt3 file could not be extracted. Seems to be a corrupted .wt3 file."
which is strange, as most of the time my 3D models are displayed correclty.
One of the 3D models is animated, but this happens randomly on both of my 3D models when launching the application (~1 on 10 launches)
It seems that the more I put 3D models, the more this issue occurs.
Running on Samsung S5, S6.
Please find attached my animated 3D model.
