In this recipe, we will create a rusty shader that will be mixed with the metal shader by a

Getting ready...

Start Blender and load the 9931OS_Suzanne_vcol.blend file. Then perform the
following steps:

slot under the Surface subpanel. In the pop-up menu, select the Environment
Texture item.

2. Click on the Open button and browse to the textures folder to load the

Barce_Rooftop_C_3K.hdr image.

3. Set the Strength value to 0.200 . Then go back to the Material window.

How to do it...

Now we are going to create the shader by performing the following steps:

1. Click on the File item in the upper main header. Select the Link item. If necessary,

browse to the folder where you stored all the blend files. Select the 9931OS_04_
metal_group.blend file. From there, click on the NodeTree entry and then select
the Metal item. Click on the Link/Append from Library button to link the node group.
