A Simple Example on How to Use "Real Bricks"

1. Open a new or existing Blender file.
2. Add an object to your scene such as a plane.
3. With the object selected, go to the "Material Properties" tab in the Properties Editor.
4. Click on the ➕ button to create a new material for the object.
5. Navigate to the Shading tab & In the Shader Editor, add a "Texture Coordinates" node by pressing Shift+A and selecting "Input" > "Texture Coordinates".
6. Add the "Real Bricks" node group to the Shader Editor by either appending it or dragging it from the Asset Browser.
7. In the Shader Editor, select the "Real Bricks" node group from the Asset Browser or the Node Editor by appending it or dragging it from the Asset Browser.
8. Connect the "UV" output of the "Texture Coordinates" node to the "Vector" input of the "Real Bricks" node group. This ensures that the brick texture is mapped correctly to the object's UV coordinates.
9. Connect the desired output(s) from the "Real Bricks" node group to the appropriate inputs of the shader nodes you want to modify.
10. For example, to change the colors based on the mortar mask, you can connect the "Mortar" output of the "Real Bricks" node group to the "Factor" input of a "Mix Color" node.
11. Connect the output of the "Mix Color" node to the "Base Color" input of the "Principled BSDF" node.
12. Adjust the A & B colors of the "Mix Color" node to control the color of the bricks and mortar individually.
13. Customize other parameters of the "Real Bricks" node group, such as brick width, height, rotation, ... to achieve the desired brick texture.
14. Render or preview the scene to see the updated brick texture with the changed colors based on the mortar mask.
