    2D Galvanized texture

    2D Galvanized texture
    by Gaurav Nawani


    Some times using a image base texture is preferable to the procedural texture as it provides more control over how the texture should appear in the 3d model. Hunting for a perfect looking galvanized metal texture can be a problem, 2d image manipulation programs like Gimp can be of pretty useful help in this regard. This time we are going to teach you how to make an ‘galvanized metal texture’ completely in Gimp in just a few simple steps.

    Step 1 Create a new Image in Gimp [Ctrl + N] of resolution 400x320. Create a selection of about 320x200 as shown in figure. Add a layer above the Background layer. Rename the layer to ‘base-color’.

    Step 2 Using the color selector dialog select the faint grey color, you can replicate the setting below in the color dialog box. Now fill the selection in ‘basecolor’ layer with this color.

    Step 3 Keep the selection and add another layer, rename it to ‘noise’. Fill it with white color. Now go to ‘filters | Noise |Scatter RGB’. In the pop up dialog box un-chek ‘Independent RGB’ and move the slíder to 0.28 and press OK.

    Step 4 Now we will generate patterns of galvanized flakes from this noise layer, without disturbing the selection go to ‘Filters |Blur |Crystalize’ and change the settings as in the image. This will create the flakes that will roughly resemble the galvanized metal, and a new layer will come up the by the name of ‘Crystalize’.

    Step 5 The texture looks pretty flat right now. Now duplicate the noise layer and on it apply ‘Filters | Blur |Gaussian blur’ of 5. Rename the layer to ‘noise blur’ and in the ‘layers stack’ move upwards of ‘Crystalize’ layer. Change the ‘layer mode’ to multiply. You can alos adjust the ‘layer opacity’ to your liking.

    Step 6 The texture is almost done, now we need to introduce some weathering into the texture, to make it look more authentic. First I am assuming you have kept the selection alive, if not then in the layers tab right-clik on the ‘base layer’ and do ‘Alpha to selection. Now add a layer at the top of the stack. Then go to ‘Filters |Render | Noise’ and generate a colorful plasma noise.

    We need only the variety of the rendered plasma noise so we will desaturate the layer. Go to ‘Layers |Colors |Desaturate’. Change the ‘layer mode’ to ‘Multiply’ and adjust the ‘Layer opacity’.

    Your galvanized texture is now ready to be used. The Final texture on the right was created with this method and few other details added
