Vray 3.4 For Sketchup 2015 Full And ClearFor V-Ray Environment with HDRI texture, the test render will highlight the possible output when render in optimized setting using HDRI as the light source and V-Ray sun as an additional light source. If you go to V-Ray Asset Editor Settings Environment Background, you can see that the default background is set to V-Ray Sky or technically the V-Ray Sun (V-Ray sunlight). Under Environment Overrides, the GI Skylight is technically turned off in default settings. However, when you turn on the GI Skylight option and choose the V-Ray sky as the light source, the render result will be similar to V-Ray default settings. In comparison to Dome light and V-Ray Environment settings, the shadow appeared to be sharper when rendered using V-Ray Sun and sky system. Here, enabling the GI skylight with V-Ray sky as the light source does not affect the output when the V-Ray sun is turned on. Enabling the GI skylight with V-Ray Sky as the light source while the V-Ray sun is turned off doesnt produce such brighter environment. Here, the light power using GI skylight with V-Ray sky as the light source does not produce a brighter environment as compared to the V-Ray sun when turned on. The V-Ray sky as the background image enable to illuminate in the material of the 3-D object. To change the parameters for Dome light follow the procedures: under V-Ray Asset Editor go to Lights click the V-Ray Dome light under Light dome, you can see two main parameters (Main and Options). Follow the parameters set-up I made for this test render experiment (See image 2.1 Dome light Setting). The shadow in Dome light HDRI set-up appears to be smoother than V-Ray sun setting. This can be illustrated in test render sample (see image 2.0 Setting 2.1.B and Setting 2.2.B). Using Dome light set-up, the lights come from HDRI map as direct light, and all effects like shadows, reflection, etc will be apparent. The advantage of using V-Ray Environment than Dome light is that you can use different maps for both lighting and background while at the same time, adjusting the intensity separately by multipliers. Optimizing the V-Ray Environment is important in order to produce a suitable environment to your scene. Enabling V-Ray sun while GI skylight is turned on (optimized) is not necessary, since you dont need to have two light source in your scene. Having two light source in one scene will just increase the render time. This render setting is the very basic of V-Ray Sun Environment. The V-Ray dome light does the importance sampling which gives you a better shadows, quicker and cleaner render than V-Ray Environment. Here you can adjust the intensity of the light source and the visibility of the background (both in HDRI map) separately using multiplier. Although, this is a more tedious work as compare to Dome light set-up from which the intensity of the light source and background can be adjusted all at once, I prefer this set-up because you have the liberty to adjust the background and the light source separately, based on your preferred settings.
