Houdini shop Study Notes 4 make bricks

1. Scenario preparation

First, use a plane as the wall and give it material, uvproject, uftransform

Add a light

2. Create a material shader Builder

Rendering Effect

3. add color to the wall

Add a colormix node between Bricker and add to adjust the color of colormix.

Rendering effect:

4. Added concave and convex effects to the wall

Add the displace along normal node. Its two output attributes are connected to the two output attributes of displacement_output, and its displacement amount attribute is connected to the border attribute of the Bricker node.

Rendering may display the following error results:

Cause analysis: the concave and convex directions are the opposite. At the same time, the intensity of the concave and convex is too large. In displacenml1, the scale attribute is changed to-0.1.

Re-rendering, display normal

5. add texture to the wall

Add a concrete1 node, connect to the first attribute primary color of colormix, and adjust the concrete gray color of concrete1 (it mainly controls the entire color of the wall)

Select 0.564 0.322608 0.081216

Make the effect stronger and output colormix to the diffuse color attribute of light.

6. Final material Flowchart

Done!
