Quick Question: Floors

[mash]

Hey I don't know if this is a stupid question or not, I apologise if it is , but I want to know how like in the trainstation in Half Life 2 the floor had that shiney effect to it. Any info please I've just started learning hammer and whilst I think I've been doing quite well on my own somethings I can't figure out. THanks.

you'll need to add an env_cubemap entity(try about eye-height above the floor)..
then when you launch the map for the first time, open the console and type buildcubemaps, which will make it work from then on.
hope this helps
