Making Metal Chains



This tutorial requires the Intermediate Chrome Curves Preset I have included for your convenience. Download the preset and save it to your Gimp user 2.6 Curves folder and restart Gimp. You may wish to simply recreate the curve as it is shown, and then save it if you don’t want to restart Gimp.

Step 1.
Open new image 300x500 pixels at 300 ppi.

Step 2.
Create a new transparent layer and name it Link. Create a vertical and horizontal guide in the exact center of your image, 250 pixels for the vertical guide and 100 for the horizontal guide. Select the Rectangle select tool and check the boxes for Rounded corners and Expand from center. Set the radius for the Rounded corners to 150, then place your mouse cursor in the exact center of your image, where the two guides intersect, and make a selection 350 pixels high by 200 pixels wide.

Image

Set your FG color to 989898 and fill the selection. Now shrink the selection by 50 pixels and hit the delete key to “cut out” the center area of the link, then go to Select>None.

Image

Step 3.
Create a new transparent layer and name it Side. Make another rectangle selection from the center, but this time 350 pixels high x 50 pixels wide, and fill it with the gray color, then deselect it. (Select>None)

Image

Step 4.
Now that we have our two basic shapes, we need to give them some form so they have a more 3D look. Turn off the visibility on the Side layer and duplicate the Link layer. On the duplicated layer, go to Filters>Blur>Gaussian Blur and use 25 for both settings. When you are finished, turn off the visibility of the blurred, duplicate layer. Select the original Link layer and go to Filters>Map>Bump Map and enter the following settings, making sure the Link copy layer is selected for the bump map.

Image

You will have quite a bit of distortion resulting from the max depth setting, so lock the alpha channel (click the little box at the top of the layers dialog).

Image

Go to Filters>Blur>Gaussian Blur and use 10 for both settings to smooth out the surface of the image, and then go back and unlock the alpha channel.

Image

Step 5.
Now turn off the visibility of the Link layer and turn on the visibility of the Side layer. Delete the blurred Link copy layer and repeat step 4 for the Side layer, following all the same procedures. (Duplicate/Blur/Bump/Blur) And you should have something like this.

Image

Step 6.
Go to Image>Guides>Remove all guides. From here you can add additional layers set to different layer modes to apply color, rust or whatever. Let’s make this one look like it is chrome plated. We will cover different ways to achieve this chrome effect in a future tutorial, but for now let’s work with the simplest method.

Since our image already has “shape” or depth as a result of the blurring and bump mapping process, all we need to do now is adjust the curves. Still working on the Side layer, go to Colors>Curves and match the settings shown below, which is the Curves preset I included called Intermediate Chrome.

Image

Once you have your curve adjusted, as shown, click OK to apply the settings. Keep in mind that using curves in this manner only works well on a grayscale image. The highs and lows of all the curves change the intensity of each area in the shape of your image to get those adjusted shades of light and dark gray that simulates the chrome look.

Image

Step 7.
Turn off the visibility of the Side layer and turn on the visibility of the Link layer., and repeat Step 6., this time to the Link layer, and apply the Intermediate Chrome settings using the Curves dialog.

Your Link layer should now have a nice chrome look as well.

Image

Step 8.
From this point we just need to save each layer as a separate PNG image. Delete the background, and turn off one of the layers and save the other one that is still visible. Repeat with the other layer. Once you have them both saved as separate images, we are ready to make our chain.

Step 9.
Close your image window and open a new image, 1000x1000 pixels, then go to File>Open as Layers and navigate to your saved PNG for the Link. Then repeat for the Side. Once you have the two saved images open, select the Move tool and tick the option for Move Active Layer. Select the Link layer and move it into position in the upper left hand corner of your image, and move the Side layer somewhere out of the way for now.

Image

Step 10.
Select the Link layer to make it the active layer, then select the Rotate tool and click on the Link image in your window to activate the Rotate tool. Using your mouse pointer “grab” one of the corners of the image and move it to rotate the image to a position similar to the one show below, then click the Rotate button in the tool dialog.

Image

Step 11.
Select the Side layer and use the rotate tool in the same manner to rotate the layer then use the move tool to position it. Move the Side layer to the top of the layer stack in the layers dialog so it appears to be “linked” with the Link layer and not underneath it.

Image

Step 12.
Start adding links and side view links to your chain, working with one layer at a time, by first, duplicating the layer, then alternately use the Rotate and Move tools to position them. You should not have to reposition a layer in the layer stack again to make them appear correctly in your image like we had to do for the first Side layer. They should all work.

You will find that each time you rotate a layer, it will increase the over all layer size in order to accommodate the new position. If you have to rotate and move several times, it begins to grow quite a bit so you may want to use the Rectangle select tool to select a smaller area and reduce the overall layer size, then go to Layer>Crop to Selection. This is not a must, however, resizing it sometimes makes the layer easier to work with. You can then continue to rotate and move your layer until you get it exactly like you want it.

Image

Step 13.
When your chain is completed, right click on each layer one at a time and select Layer to Image size. Turn off the visibility of the background layer, and right click anywhere in the layers dialog and select Merge Visible layers. When the dialog box pops up, click Merge to combine all the link layers, then turn on the visibility of the background layer.

Step 14.
Select the merged layer with our chain, and go to Filters>Light and Shadow>Drop Shadow and apply these settings.

Image

Our chain is complete!

Step 15.
Just to make our image pop a bit more, lets do something with the background layer.
Set the FG color to B7B0DC and the BG color to 333333. Select the Blend tool and set the Gradient to Foreground to Background. Set the shape to Radial and using the rulers at the left and top of your image window, move your mouse cursor to the center of the image and drag from the center to one of the corners to apply the gradient.

Image

Merge all your layers again and you’re done!

I hope you liked this tutorial. Next up is Metal Wurx –Part XI where I will show you how to get that hammered metal look like this.

Excellent tutorial. I'm sure I'll find some uses for that.

Thank you Erisian. The next three in this series all have to do with textured metal. Stay tuned. If I ever get my pavers and stone walls finished, I'll have more time to devote to completing the last 6 segments.

Thanks Drac. Another easy to follow tutorial with good results. :)

One problem, with the bump mapping, you don't say which map type to use. At first I thought spherical but sinusoidal worked better.

That is a superb tutorial. I really enjoyed doing it. I made my chain gold.

I agree with you Erisian. Yours looks really good. The others are too, but I think the sinusoidal selection looks better. :hehe

I'll have to go back and try that. I saved my layers and hopefully I can do a sinusoidal bump over them. May have to start from scratch.

oh, that's some serious bling, O :)! with my general fussiness about metal i'd say the shade was more like slightly aged silver, though. one of the loveliest metal shades there is!

Careful O. Da boys in the hood might try to grab your gold chain. :rofl

Sorry about the bump map. I just went back to check cuz I swear I had a screenshot of the bumpmap settings and sure enought it was there alright. Problem is I guess I messed it up somehow cuz the drop down menu covered up the mode which is definitely Sinusoidal. :oops: I'll try to be more careful in the future.

the one problem i had was the guide line numbers didn't work. he has the vertical at 250 and horizontal at 100. if you look at the pics he posted even his wasn't at these numbers.....but i figured it out..was just wondering if anyone else had this problem and that maybe he made a mistake with these numbers for the guide lines.....

Looks like my day for egg removal on my face. You are correct, I made a typo. should have been 150. All fixed now, I edited the tutorial.

I didn't realize there was a problem with that method as I used the New Guide by percent. 50 percent W & H worked fine.

Spot on O. I used RobA's version of grid (number of divisions = 2) Also, when Drac gives a specific size for a selection, I use fixed size. Makes life a lot easier.

Not sure what you are talking about. I never have made rust before nor do I have any plans for a tutorial. I always use a pic or pattern. Kevin is the rustmeister. Someone posted a fantastic image of some rust made from scratch a while back that was extremely realistic. I'll have to hunt it up again. They never did answer my post asking how it was done. Probably have to kill me if he told me. :mrgreen:

You did leave a clue in your brushed metal tutorial. A little adaptation is all that's needed.

OK, now I need to buy a clue. Brushed metal? I'm lost. What are you talking about? How does that get to be rust?
