Tutorial: Precious Metal


This tour illustrates how to create metallic textures. In this example, we will create a gold texture. You should already know how to select functions and load presets. This was explained in the previous tutorials.

Step 1: Rendering the bump map


Create a new 256x256 texture.

Select the function Generator/Perlin Noise and its Bumpmap Preset.

Apply the function to thenew texture.


Step 2: Adding noise to the bump map


Select the function Noise/Pixel with Default settings.

Apply the function five times to the texture (Hint: You can right click the texture and select the 5x menu item).


Step 3: Creating the reflection map


Switch to the Generator/Turbulence function.

Load the Default settings at the Presets Panel.

Run the function on another 256x256 texture.


Step 4: Increasing the contrast


Choose the Color/Contrast  function.

Relative to the Default settings, set the Amplify Value to 500%.

Click on the turbulence texture to increase its contrast.


Step 5: Colors of gold


Select the function Color/Convert function.

Verify that only the Hue and Saturation on the HSV Channels panel are enabled, Brightness must be disabled.

Set the Primary Color toRGB(220,160,60) and apply the function to our future reflection map.


Step 6: Shading


Launch the Shader from the Tools Menu or with theicon.

Load the Bump Map from Step 1/2 as Heightmap.

Use the golden Reflection Map as Environment Map.

Relative to the shader's default options, apply these settings:

Heightmap Amplification=25%, Smoothness=30%
Surface Opacity=100%, Shininess=8%, Strength=13%
Enviroment Reflectivity=35%, Distortion=100%
Color Scaling=100%, Bias=-20%
Light Color 1 and 2 both toRGB(220,160,60)
Move the two Light Sources to the upper quarter of the Preview image

Press the Render button to finish the gold texture.
