The intensity and colors of the sky will be physically accurate based on those settings. Setting up the geographical position of our scene allows us to create accurate day time illumination for any given date and hour of that day. The main point is that the illumination (color and intensity) depends on the Sun's position. This part demonstrates the basics of setting up a V-Ray Sun and Sky System. In our workflow, we enable it in each step where we adjust the illumination and then disable it in the end for the final render. It allows us to render the entire scene with a single diffuse material which speeds up the rendering. This option is useful when setting up the illumination of a scene in which materials are already present. This method saves memory by keeping only one instance of the geometry in the RAM When working with proxies it is better to make copies of one proxy rather than importing the same geometry multiple times with different v-ray proxies. Per Area - guarantees equal density of the grass across faces with different areas.
The geometry can be exported from any platform that supports V-Ray (into a. V-Ray then loads the geometry during render times. The proxy allows us to store any geometry on the hard drive and load it to SketchUp without impacting the poly count and performance of SketchUp. We begin by setting up some trees and bushes using the V-Ray Proxy. Since vegetation is usually very high poly and SketchUp cannot handle that much geometry we use several V-Ray functionalities Th e main module begins with setting up some vegetation. These were made so that you can start at any one of these stages and follow the steps in the video to the end. You can find scene files with the same names in the Lesson 2 folder.
We use the VFB Lens Effects to further enhance the night time setupĮach section is annotated in the video.

We show how to setup night time illumination using the Dome Light and some of the lights covered in the Extra modules of Lesson 01 We switch the illumination to image based lighting – using a panoramic high dynamic range picture of an environment and V-Ray Dome Light to illuminate our scene Using the Physical camera option we adjust the exposure and white balance of the image We use the V-Ray Sun and Sky system to match the illumination at a specific place in the world at a given time and day of the year We use the Override Material function to speed up the lighting process Trees and grass require lots of polygons so we use V-Ray Proxy and V-Ray Fur to generate them efficiently
