Learn to make cutscenes in unity3d by building a stealth Game.
Objective: Working on Submeshes Geometry.
Sub mesh Geometry are 3d objects which created with 3d software or modeler software that allow this object to be able to take more than 1 material at a different parts.
We need to make the left collum look identical to the right.
In the first step, create a material and rename it a black mat.
Select the black mat < albedo, select black marble texture adjust the metallic and smoothness option to get a black metallic look.
Select the collum and start dragging the material to element 1 on the material option of the mesh renderer.
To get the rough dark look change from shader mode to AutoDesk Interactive, remember the standard shader roughness has been renamed to AutoDeskInteractive.You can play with smoothness and metallic to get a dark gloss look.
Now create another material, renamed White_mat, then add white marble texture. Adjust the metallic and smoothness.
Select the collum start, then drag and drop this material to element 1, then change the shader to Autodesk Interactive.
create another material to give the look of gold, use only normal color to get gold color, then adjust the metallic look and smoothness.
Select the column start, then drag and drop the material into the gold sub mesh.
