Render watermark

[Honzix]

Hello, how I can render Watermark (or image backgorund)with new version of Vray sketchup 3.4? I found great tutorial for this with Vray 2.0 http://www.sketchuptexture.com/2013/10/testing-vray-render-using-su-watermark.html and it works fine but no for new version. The settings is diffrent and maybe I do something wrong I don´t know.

Thank you.
