Light coming through window --> Shadow effect

[_Meitsi_]

You know HL2 train station in the beginning of the game. Theres big hall where are several people in line waiting for lunch (?) from that machine, and theres several combines hitting you with stick if you get too close.

In that hall, theres BIG windows and light coming through them. The window texture has some "bars" going thru the window, like in some real windows... The point is, how do i get realistic shadow for my map? I made small room with window, and outside that window, theres spotlight pointing to the room (so it looks like sun) and the window is covered from outside with windows size "Mini skybox" so you could see sky from the window, not just pitch black. How i get window's texture affect the shadow the light casts so it's not just round-edged normal shadow... i want that window textures bars and things cast shadows so it would look realistic... How is that possible? (And sorry, if you think my english is poor)

So I need to add light_enviroment to every place I wish use that effect? I thought light_enviroment is needed onlu once in a map

It won't work because the glass used in the trainstation is an entity, not a brush. It can be found in the props_trainstation folder.

I wonder if it is done through lightmaps or whether they built a mockup window behind the glass which would be used to cast shadows but can't be seen at render time.

maybe make a grid infront of the window (on the side you see) made of toolsblocklight?
I haven't tried this yet, just a suggestion.
