Hello Chris,

First I want to highlight that the models do not have textures. Just materials. In the process of importing the .FBX to Unity, you will have to assign the materials.

You can find the Android app Unity project on Github.

Anyway, those models and code are outdated and I don't recommend using them.

Right now I am developing a new app for browser and PC, which will include the new models, optimized code, and a solid base to create an advanced app.

I will publish the whole project in the next days/weeks.

I recommend you to use my code as it will save you thousands of lines of code. Probably anything you want to do is already done.

Stay tuned,

Lluis.
