Can’t see any error. This code looks just fine. Run it at the end before returning the scene.
Edit: OK, just saw what your problem might have been. ‘adt’ in this script goes for your ‘advancedTexture’.
A matter of naming things. All you have to do is simply replace ‘adt’ by your name for the ‘advancedDynamicTexture’ which you called in this PG ‘advancedTexture’. Next it should run like a charm
