Using V-Ray for SketchUp, when loading a Dome light+ HDRI in default setting, the render result will be darker in nature (See image 2.0/ Setting 2.1.A). 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. 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. Under Environment Overrides, the GI Skylight is technically turned off in default settings. 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). When set in default setting, notice the sunlight is enabled. In V-Ray default setting, V-Ray Sun and V-Ray Sky are special features which are provided by the V-Ray Renderer. For 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. For V-Ray dome light with HDRI texture, a comparison test render was made using default setting and optimized setting.

I also added a Sphere model inside the scene with silver polished material in order to see the reflection of the sky.ДЇor V-Ray Sun and Sky System, I set up a basic scene in default setting and lit it a couple of different ways, (enabling and disabling) V-Ray sun, background, and GI (Skylight). In order to fully understand the possible render output in V-Ray using various environment settings such as V-Ray Sun and Sky, Domelight+ HDRI and V-Ray Environment + HDRI, I made a simple rendering experimentation that highlights different parameters or settings which generally affect the tonality and atmosphere of the rendered image output.Дuring the test render experimentation, I enabled the material override and set the water pool to вЂњCan be OverriddenвЂќ.
