I worked a little more on this Project.
I modified the design a bit more in Google SketchUp.
I went into Adobe Photoshop, and "tweaked" a photo of a brick wall I found on the Internet. I combined a few different images to give the wall the whitewash effect.
In Google SketchUp, I applied the image as a material to the wall, and adjusted the settings in IDX. I added a few lights, and made a few more adjustments. All in All, this was a quick, preliminary (pre)Render, and spent only 30 Minutes on setting up Light placement & luminousity settings, and Rendered as a High Quality Image with IDX Renditioner.
IDX gives me real good results very quickly, but it is harder to get over the next hump of Realism. It is a good tool.
