Small test of the stargate system inside unity engine , new model of stargate, kawoosh and dhd create by microman ,the SGU ramp came from GMOD and the other stuff came from the old mod on SA.
I used a FPSKIT for the player and weapon you can find it here : http://armedunity.com/
Music : A day at SGC - Joel Goldsmith , Audio Extract from the episode Aftermath from SGU and Audio Extract from the episode Gaunlet from SGU too.
How it works , the gate work like the older gate on the SA mod except for the manual gate , you put an adress on the value and the gate dial as you can see.
That is not showed on that video is the gate system have other feature such as energy feature or the offworld but maybe in another video i will put that.
