Thin Square Block

Since i am afraid to even move my cursor in any 3D modelling program, i am asking you.

Just a square block with the size of HL2 fence model, or bigger, with the portal wall texture from one side and the floor texture from the other side. Both the white ones that someone made Portal2 look-a-like, the ones you can create portal on.

Thanks.

//edited, since i forgot about no Source Retail stuff.

Anyone?

Damn, where is my automerge

Where is my pic, brb.
