[/codeblock]
The [code]SurfaceTool[/code] now contains one vertex of a triangle which has a UV coordinate and a specified [Color]. If another vertex were added without calls to [method add_uv] or [method add_color] then the last values would be used.
It is very important that vertex attributes are passed [b]before[/b] the call to [method add_vertex], failure to do this will result in an error when committing the vertex information to a mesh.
Additionally, the attributes used before the first vertex is added determine the format of the mesh. For example if you only add UVs to the first vertex, you cannot add color to any of the subsequent vertices.
