Part I: Adjusting the GI settings
Step 1. First render 1.1. Open the scene (which can be found here). 1.2. Assign V-Ray as the current renderer. Since the default V-Ray settings are not very well suited for a fast initial preview, we'll make a few quick adjustments before the first render. 1.3. Check the Override mtl option in the Global switches rollout, click the button next to it and select a default VRayMtl material. 1.4. Set the Image sampler type to Fixed. 1.5. Set the resolution to 400 x 325. 1.6. Set the Region size in the System rollout to 32 x 32 pixels. 1.7. Optionally, you can turn on the Frame stamp to print the render time on the image. 1.8. Render the scene:

Step 2. GI preview 2.1. Turn GI on from the Indirect illumination rollout. 2.2. Select Light map as both the primary and secondary GI engine. 2.3. In the Light cache rollout, set the Subdivs to 500, since we want only a fast preview. We'll return this to 1000 for the final rendering. 2.4. Set the Interp. samples of the light map to 5 for a faster rendering. 2.4. Turn on the Show calc phase option for the light map. 2.5. Render:

The result is quite noisy, but it does give a good idea of what the scene lighting is like. Step 3: Tweaks 3.1. Since the scene looks too dark, we would like to brighten it a bit. There are several ways to do this. One is to increase the power of the lights. However, this will make the directly lit areas of the image, like the
