GMod Portal gun

Hi guys.
I search a working portal gun.
I found much like the from mahalis, but there is a bad texture.
You know a good Portal gun?

If “U” know a good grammar.

You don’t need to download the renderx module, it’s included in Garry’s Mod

Use this if you don’t know how to use SVN: http://www.facepunch.com/showthread.php?t=688324
