Have got some doubts about things never seen in half-life....but don't know if they're possible....
1st-Can models have a moving shadow?(eg:monsters)
2nd-Is half-life capable of reflective textures? (like swat3)
3rd-Can be trigger_teleports be triggerable to teleport the player to a location by a multi_manager (it is for the player to not have to walk through the entity)
I'm waitin' for yer answers.......
