This video tutorial of 3ds max 2012 contains a very simple method of creating realistic grass using material in vray render. To create realistic grass first we need a ground object, to create a ground object or you can say a surface, simply go to standard primitives and choose plane and select square in the creation method and draw a plane in your top viewport. After making the surface then you need to create a 3ds max vray camera.

To create a vray camera go to cameras and choose vray from the drop down list and select “VrayPhysicalCamera”, as your top viewport is still active so draw this camera on your top viewport as shown in the video. Go to your perspective viewport make a right click of your mouse on the left corner of your viewport, and choose “vrayphysicalcamera001” from the list. Now your 3ds max perspective view will be change into vrayphysicalcamera view.

Select your vrayphysicalcamera and go to modify tab and make some adjustment in your vray camera parameters such as, f-number, vignetting, custom balance, whit balance and shutter speed as shown in the video. As we also need some objects in our scene to see the grass in action. So you can place any object you want and place it right in the front of vraycamera, for this video we are placing a 3ds max torus knot object.

After creating these all above steps now it’s the time to make some rendering adjustments, so as usual go to your render setup window and choose vray render as your rendering engine, now as you can see there we have vray rendering setting parameters, go to vray tab and make some setting as shown In the video, to create realistic grass we need a day light system.

To creating a day light system in 3ds max 2012 choose daylight from the right panel and and drop it in your top viewport. From the daylight parameters, chose vray sun and as you can see the daylight parameters will be change into vray sun parameters now make some changes and adjustments in your vray sun light as shown in the video. Now it’s the time to create the grass textures. Select your plane object and apply a uvw map modier on your plane, next go to the modifier tab from the tool bar and chose v-ray displacement mode from the v-ray. Select 2D mapping in the parameters type, apply a texture in the texmap slot as you can see in the demonstration. You just need a grass texture to apply a displacement map, as we are now ready to take a test render, so if you are not satisfied with the render output you still can make any kind of adjustment that you want.
