Elevator Babylon version

Welcome to my Babylon version elevator!
This is my first Babylon app and the second version of the elevator written with javascript and using a 3D model with the Babylon.js component!
If you are curious, check out the CSS Animated version too!
About the 3D model: The concrete block is the building; The small yellow cube is the elevator. The blue 'lines' for each floor boundary.

Known bugs:

The engine crashes if I raise too much the number of maxSimultaneousLights in all my materials... So if you add 4 buildings with 4 elevators each, you'll notice that some of the elevator's light will be off...
I'll probably have to create a separated material for each elevator and building so I can apply only their own lights to themselves.
Zooming with mouse wheel is within canvas is causing the page to scroll...

Fixed bugs:

Sometimes when pressing the button to go to a floor lets the elevator model inconsistent and it stops moving.
