                                   or this tutorial we will be taking a look at the worklows
          3ds Max,                 and techniques used for creating this grimy window. Keep
          Forest Pack Pro      Fin mind that a lot these worklows and techniques can
          Paul Roberts          also be applied to a wide variety of materials and surface
          itoosoft.com          types. In fact, whether I am creating a tile loor, rocky ground
                Paul is an experienced   or brick wall, the worklows and nodes discussed in this
                3D environment artist   tutorial are what I turn to for those types of surfaces and
                and educator working
                as training manager at   more. Additionally, this type of worklow is very friendly for
                iToo Software   any current PBR game art pipeline. The main reason for this is
                                that everything is PBR compliant, which we will go over in the
                                coming steps. One more thing regarding pipelines: this
                                worklow is completely non-destructive and highly adaptable.
                                Any artist can go back and make any kind of adjustment, from
                                the amount of window panes, the types of windows, how
                                glossy those windows are, how much grunge, the colour of
                                the paint and so on. Not only that, but a wide variety of
                                window types can be made from this one setup, which not
                                only saves time for the artists on the loor, but helps to
                                keep the look of the windows very similar, which has a
                                pleasing effect and creates cohesion across the windows.
                                Let’s jump right in!

                                     Create the ‘brain’ Starting off the industrial window
                                01  material in Substance Designer I will use the Tile
                                Sampler node. From this node I will get a Multi Value Grayscale
                                map which I will leverage throughout. I’ll also create a Tile
                                Generator node that has similar settings and will use the
                                Gradation pattern. This will enable us to achieve a great tilt on
                                the windows, which will add a lot of life to them when the light
                                rolls across the surface. I will plug the Multi Value Grayscale
                                map into an Edge Detect to create initial masks and gain
                                separation between the glass and painted metal framing.
                                      Establish windows and metal framing Using
                                02  Uniform Color and a Blend node I will give initial value
                                to the height map. I’ll plug the mask created from the Edge
                                Detect node in the irst step into the Opacity of the Blend node.
                                Next, I will also use the Bevel and Curve nodes to create the
                                painted metal framing. The Bevel node will create a nice ramp
                                that we can then plug into the Curve node, which we will use to
                                give a reinforced and structurally sound metal shape. I will plug
                                the output from the Curve node into the Blend node with Add
                                Linear as the Blending Mode.

                 Free                 Add window pane details Glass windows are
           dOWnLOads            03  rarely lat, as there is typically a bend or slight
           from ilesilo.co.uk/3dartist  undulation to the surface. First, I take a blurred version of the
                                glass mask and plug it into a Blend node with the Blending
           • Tutorial screenshots
                                Mode set to Screen. This gives a rounded bend to the panes.
