In this 3D Studio Max Tutorial I want to introduce Vray Fur. I am not going to explain all parameters one by one. it is what you would find in Vray help documents. Here, I try to show abilities of Vray Fur with bringing some examples.

I haven't discuss about lighting and rendering parameters in this tutorial as it is all related to your own scene that has been added Vray fur. To make sure that you can study these tutorials, I have provided the start scene and end scene of each tutorial.

 

Final Result Preview

 
 
 

Part 1: Creating Rug with Vray Fur:

 
 
 

Step 1:

 

Create a Plane with Length and Width of 100 and 16 segments for both sides.

 
 

Step 2:

 

In the Create Panel, under Geometry section, select VRay from list. Four Vray objects will appear. Now you can select VRayFur object. But first you need to select your plane (vray fur destination) from the scene. Then VRayFur will be active and you can click on it.

 

After Clicking on VRayFur button, the new icon will appear on the center of plane object. You can move this icon. This will not have any affect to position of filaments on the plane.

 
 

Step 3:

 

Set the VrayFur parameters same as below picture.

 

Length and Thickness control the length and thickness of filaments. Bend and Gravity fields will help to set up filaments curvature. In the Knots filed you can define the number of segments that create a filament. As much as you increase this field, the filament will be smoother but be aware that it would increase your rendering time.

 

In the Variation group you can change global variety of Direction, Length, Thickness and ravity. Here I just change Length Var. In Distribution group you can define how filaments scatter along surface. There is really not much difference between Per face and Per area. What is important is to find the best value to show what you want.

 
 

Step 4:

 

Add a Vray material to both plane (destination) and vrayfur. It is better to use same material for plane that used for vray fur.

Now you can render your scene.

 
 

Part 2: Creating Carpet with Vray Fur:

 
 
 

Step 5:

 

For creating carpet, repeat step 1 and step 2. Then change VrayFur parameters same as the parameters on the picture below.

 
 

Step 6:

 

What's very cool about Vray fur is you can use texture instead of material and filaments will get that texture color. Here I use a carpet map as diffuse of vray material and applied it to Vrayfur. For better result also applied same material for Plane of carpet. When you render the scene you will see the filaments change according to the color of texture that set on them.

 
 

Part 3: Controlling Length of Vray Fur:

 
 
 

Step 7:

 

Repeat steps 1, 2 and 3 to create a simple rug.

 
 

Step 8:

 

In Maps Rollout in VrayFur parameters, you can see different slots for controlling Vray parameters by maps. Here you have 2 kinds of slots. In the "mono" slots you just can control option by grayscale maps while in "RGB" slots you need to define colors.

 

For this tutorial, I added a Checker map to Length map in Vray fur parameters. The white color is the area that filaments have the highest length and as much as it be darker, the length of filaments also will reduce.

 
 

Step 9:

 

For better result I added same checker map in as diffuse color of Vray material for both Vray fur color and plane. Then change the white and gray colors to what I wanted as my rug be.

 
 

Part 4: Creating Grass with Vray Fur:

 

What you have done in previous steps was applying color or texture to the filaments horizontally. But sometimes same as grass you need to apply material vertically. It means that bottom of each filament have different color with its tip. About Grass we need to use dark green at root and lighter green at tip of each filament.

 
 

Step 10:

 

Below picture show the grass land that I reduced filaments and also increased thickness just for preview. I use a green material for vray fur (grass). But as you can see whole part of grass has steady color.

 

In the next picture I applied Gradient Ramp to diffuse color. For demonstrating coloring distribution in Vray fur I use two solid colors. The result is same as what happened in Carpet rendering and colors scatter horizontally. Some get red color and others get green.

 

But sometimes same as Grass, we need to apply out material vertically. For this you need to change something in both material and Vray Fur parameters.

 

First make sure in your Material texture parameters, WU is selected. Then in Vray Fur parameters also check "Generate W-coordinate" option.

 

Now if you render the scene the result will be same as below picture. Right color is at bottom and left is at top.

 
 

Step 11:

 

For grass you can use same setting I have shown in below picture.

 
 

Final Result:

 

Hope you enjoy of this tutorial.
