Grout Material

Set shader/color for grout.

Floor Generator has a feature that allows to automatically generate Grout and control its Depth.

It is possible to control Grout color/shader inside main flooring material.

Option 1

Add Grout_Material Node (this is a group of nodes which comes together with Floor Generator).

Link this Node right before the Material Output Node.

Set shader parameters for your Grout.

Option 2

Use "Grout" Attribute Fac output when you need custom Grout shader. In this example Grout has Emission shader.
