* Ok. You must have the latest version of Google SketchUp and Vray version 1.00 (I think, I've downloaded so many that do not know what is), but I know that many have no idea what this is, I leave here the link to download the Vray for sketchup 6 and 7:

** The scene in SketchUp 7 (Please, this tutorial ONLY WORK WITH THE LATEST VERSION SketchUp and VRAY VERSION THAT I PUT UP) base tutorial:

*** Here is an archive HDRI to light the scene

visopt
**** The file already configured before and have installed the vray well located the file HDRI to load quickly:

***** Given that many have no idea how to set the render, I leave a predefined file for upload options Vray. And how do you do? as easy, follow these steps:
1. Download the previous scene and visopt *.* file extension at the top.
2. If you are unsure what version of Vray you have and you do not know if it'll work with that scene and setup, we recommend you download the compressed file with the version of vray that I used, I recommend it widely, I think, is better than the latest version (my PC is Vista 64 bit, 4 gb ram, core 2 quad processor and the latest version of vray I ran too slow). But to save you setbacks, this version I have:
If you look under the tab "About" is a butterfly image and a caption that says "Vray for Rhino", ie in this version, for Vray latest bone the 1.05.3, and change. It is very important to work with this version, otherwise it WILL NOT WORK THE TUTORIAL.
3. You click on the icon bar options Vray in Sketchup (the icon with an "O") and loads the file bien.visopt I leave. File> Load> bien.visopt ... location depends on what you downloaded, get it.
4. Make sure the HDRI image is loaded into the option of "ENVIRONMENT" marked with a letter "M" capitalized:
5. Be sure to load the same image HDRI in the Background option, the color chosen at this time for the background and the GI is irrelevant but keep it checked, the bitmap image loaded, and marks the option of "UVW" and "environment", in the "GI Skylight" as in the "Background". Load it using a bitmap, click on the "m" lowercase to load the HDRI image. Load the one you like or use the I stopped in this tutorial. Be guided with the previous image.
6. Since everything is loaded, Click on the option render (blue cube) Vray bar. The result has to be something like:
7. If you realize that there are some light spots in the dark, like dark regions, due to this "HSPH. Subdivs" or "Hemispheric Subdivs " (for connoisseurs of vray for 3ds max this they may be well known). So, the less subdivs less quality, but also less time rendering. I recommend that you manually try different amounts, beginning 50 Proofing 300 for final results. Here is where you change this setting, under the tab Irradiance Map Vray options:
8. A result with HSPH. subdivs uploaded to 300:
you can see at the bottom of the image rendering time increased dramatically, but the results are worth it. About 25 minutes. Everything depends on the outcome that you require and based tests.
****** I hope this little tutorial for Rendering with HDRI you have served. *******
grateful If you do not kill you today when you sleep. AH! and soon the next tutorial, rendering an interior scene with global illumination. Total Thanks cursed.
