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 the |
new 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 to |
RGB(220,160,60)
and apply the function to our future reflection map.
|
Step 6: Shading |
|
|
|
|
|
|
Launch the
Shader from the Tools Menu or with the
