About this image

Finally managed to get the right env map setting and alpha transparency flag to recreate true glass effect in game...

The possibilities...

The glass material behaves realistically based on the available light source:

b) Ambient light

d) And of course, tinting the material is also possible, while maintaining its glass properties.
