bending pipes
well, finally misery will reveal how he did the metal pipes on battleangel and plasma. all in all it's pretty easy to create and if i tell you how i did it, you will laugh your balls off. or not. the reason why i'm doing a pipe tutorial is, that i have seen quite a ton of those and most of then suck or are so unprecise that i can't figure out how it should can possibly work that way.

make a new file. make a new layer, go to gradient, go into the gradient options and select a gradient from black (0%) to white (50%) to black (100%). (you can also use the reflected gradient tool with a normal black/white gradient, but i an still used to ps4 where you did not have this feature).
make a rectangular selection, and fill the selection with the gradient.
|
|
keep the selection and get yourself the airbrush or pencil tool. make a white line to the left and a black line to the right (whoa, a 3d effect)

next thing is to duplicate the thing quite often. the easiest method is to press (alt) and (ctrl) while you still have the selected item. if you drag it, you can move a copy of the selected item on the same layer. place it exactly next to the first one. select both and repeat the copyprocess. take those four etc... until you have enough segments.
now to get to the tremendous trick: select the pipesegments and copy them, make a new file and paste them into it. go to (image) -> (canvas size) and make the file the same height as the width. now you should have something like shown on the left.

now go to filter -> distort -> polar coordinates -> rectangular to polar. boom. here we go.
the method also has a disadvantage: due to the extreme distortion that is applied to the image, the images gets a bit edgy at 100%. so be sure to make the pipes bigger than you need them, and resize them to 50% after applying the polar coords filter.
