Glass
Malcom reached out after asking the question and provided a bit of information regarding glass and such. When you're setting up your material in GIMS Evo here's what he recommends.
Vertex Color Recommendation: YELLOW
This is recommended because it looks good at all hours.
Shader: Glass
Parameter Set: glass_pv_env

If that link above somehow manages to expire. It's basically a gray .dds file with a 10% alpha channel.

In that same texture box you should set these parameters:
Type: Regular
Pixel Format: A8R8G8B8
Usage: Unknown
There are also a handful of boxes below this one that have sliders.
You won't have to change these too much.
Probably only change Specular Intensity
to 0.8
.
Mess with these for different effects.
Should look like this if you have lighting setup in your 3DS Max instance.
