Sub Meshes in Unity
Objective: create materials to modify the look of the column
In Unity we can have 3D models that can have more than one material in the same geometry. Those materials are called sub meshes. As you can see in the scene below there is a column with a white and a black section. Those are the sub meshes in that 3D model.
First I went to the project window and created a material called black_mat. I this material I added a texture selecting the little circle in the Albedo channel and modified the values of metallic and smoothness.
Then I create another material for the white section. Same thing, added a texture and modified the metallic and smoothness properties.
Next I selected the pillar and just dropped each material in their respective places in the inspector.
And that’s it!!! A new beautiful column with different materials.
