Per Face - each face has the same number of strands, if the faces have different areas the density of the grass will vary.

We can choose between controlling the number of grass strands in two ways: The Distribution parameters allow us to control the density of the grass. The Variance parameters allow us to introduce some randomness in the grass so it looks more natural - higher numbers mean greater variation from the values determined in the Basic Parameters. The Length, Thickness, Bend and Taper parameters allows us to control the look of each individual strand. In this module, we use it to quickly setup some grass for the front lawn. The V-Ray fur is a procedurally generated geometry that can be used to simulate effects like fur, hair and grass. vrmesh file) or any platform that can export.

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
