grass and realistic sky environment with Mental Ray in 3ds Max.
First, you will
create a Plane object, and then add a Noise
modifier. On top of that apply a Hair and Fur
modifier. This will be used to simulate realistic
We create the sun and the sky with the Daylight System.
Add a Lens and Ring Effect for the sun and a
cool realistic effect.

How to make a Grass Field and
realistic Sky environment
Create a plane from Create > Geometry >
Plane. Use Height: 100 and Width: 100. Then add a Noise
modifier to the plane. Select the plane and go to Modify panel and
Use Seed: 2; Scale: 70 and on the strength, Z:
Now apply Hair and Fur modifier on it. Use my
values. Hair Count: 30000; Scale: 20; Root
thick: 3.5. Keep the other values unchanged.
On the material parameters rollout, Use Occluded
Amb.: 10; Tip color: 115,115,45(r,g,b); Root
Color: 79,102,45(r,g,b); Hue Variation: 30;
Specular: 40; Glossiness: 90 and keep all
other values unchanged.
Now use Orbit, Zoom, hand etc tools to get a perfect view on the
Perspective viewport. Once you get a perfect view, press
Ctrl+C to create a camera from that view.
Now go to Rendering > Render Setup. On the
Assign renderer rollout, click on the button next to the Production and choose
Mental Ray renderer.
Now we’ll create the sun and the sky. Go to
Create > Light > Daylight System or on the Create panel
go to system and choose daylight. A dialogue box will appear, select yes to
apply a physical sky environment. Make the compass of the
daylight where the camera target is. Now on the modify panel find
Position option and choose Manual. Now you can
drag the sunlight using move tool. Drag the sun to a position that matches the
camera view angle and get a nice position to render. To position the sun
correctly, you have to make render several times.
On the sunlight, choose mr Sun and Skylight,
choose mr Sky then a dialogue box will appear. Press yes to
apply mental ray physical sky environment.
Now go to Rendering > Effects. On the effects,
click Add and choose Lens Effects. On the Lens Effects
parameters rollout, select Ring and click add(>) button.
Now on the Lens Effect Globals rollout, use Size:
27; Intensity: 58. Click Pick light and select the sunlight
from the viewport.
Now on the Ring Element rollout, change Size: 90;
Intensity: 75; Plane: 780; Thickness: 10 and have other values unchanged.
Now add 3 more Rings and only change the values on Ring Element
rollout, for first one Size: 30; Intensity: 35; Plane: 500; Thickness: 2. Second
one, Size: 1; Intensity: 75; Plane: 450; Thickness: 20. And the last one, Size:
0; Intensity: 75; Plane: 345; Thickness: 10. Also for this one, select the red
color on Radial Color and change it to yellow color.
Now Render the scene and see the Final Result.
