### **Example: Stochastic Tiling**

The** Stochastic Tiling** parameter can help you achieve a non-repeatable look by randomizing the texture mapping in each tile. In this example, we show how to render a brick wall with the help of Stochastic Tiling.

We use a Bricks Weathered material available in the **[V-Ray Material Library](https://docs-chaos.atlassian.net/wiki/spaces/VSKETCHUP/pages/109779669)**. Then we open the texture linked in the **Map** slot of the **Diffuse** **Color** of the Brick Weathered material and set the Placement **Type** to **Mapping Source**. We click on the **UV Placement Source** icon and select *UVW Placement. *

Brick walls are usually built in horizontal rolls so we remove the random rotation caused by the **UV Rotation** by setting it to *0*. We enable **Stochastic Tiling** in the UVW Placement and set **Tile Blend** to 0.01. Default interval values of **U** and **V offset** from *0* to *1* mean a full tile size can be used as offset. The randomized look can be fine tuned with adjusting the step value for the randomization. Picking the correct offset **Steps** will result in aligning the brick rolls in adjacent tiles. See the results with various steps in the rendered images below.
