Creating grungestract brushes



This tutorial will explain the steps that were taken in the creation of this grunge pack.


1)Open up the GIMP

2)Create a new image (500 by 500 pixels) with a white background

3)Click on "dialouges>brushes"

4)Click on the "create new brush" button (it looks like a sheet of paper)

5)Enter the following settings (it's really) up to you.




6)Double click on the brush icon in the toolbar

7)Click on "use color from gradient" and choose the gradient shown below





Brush across the image and fill it up as shown





9)Select "Filters>Map>Displace" and displace the layer on itself





10)Desaturate the image (Layer>Colors>Desaturate)

12)Select a small roundish portion of the image

13)Copy the selection





14)Click "file>new image" (should match size of the copied part)

15)paste the cutout onto a new layer





16)Click "Layer>Transparency>Alpha to Selection"

17)Click "Select>Feather">

18)Feather the selection by a decent amount of pixelness




19)Invert the selection (ctrl+I)

20)Clear the selection (ctrl+K) untill there is no definent cutoff on the edges





21)Flatten the image

22)Set the mode to greyscale

23)Save the image in the brush folder (C://Program Files/gimp/share/2.0/brushes) or (/usr/share/gimp/2.0/brushes/ on the penguin) as abstract1.gbr

24)Repeat steps 12-23 a couple of times

25)Create a new image of 500 by 500 pixels with a white bg

26)Open the brushes dialouge box (Dialouges>Brushes)

27)Click the refresh button

28)Select one of the brushes that you just created and start filling up the image, switching brushes regularlly





29)Re open the layers dialouge (ctrl+L)

30)Right click on the BG layer (should be only layer)

31)Select "Add alpha channel"

32)Select "edit layer attributes"

33)Type in a bunch of jibberish (not a necessary step, but it's fun enough)

34)Create a new layer and move it under that)

35)Select "Filters>Render>Clouds>Solid Noise"

36)Max out on everything exept for random seed (thar'd be impossible)





37)Set the brushed layer to overlay, and duplicate it





38)select the bottom layer and motioin blur it at 0 degrees with a maxed out length (in this one you really don't need to do it in the other direction)

39)Bumpmap the layer on itself with the following settings (or whatever you choose)





40)Sharpen the bump mapped layer a bit. (or a large amount, it's up to you)

41)You should have something like this (If it's too light then make a new layer on overlay and select everything then "edit>copy visible" and paste it on that layer)





42)Sharpen the image a bit

42)Repeat steps 12-23 only with bigger selections and larger feathering amounts (also more ctrl+K ing)

43)Delete the brushes created in the beginning (unless you really want them, but why would you?)



Feel free to realease brush pack out on the net with your newly created grungestract brushes in there, but just don't claim the method of creation to be your own.

On the lines of giving credit, a large influence on the developement of these brushes was a failed attempt at imitating MobiusOne's grungestract pack. I have yet to figure out how he did his, but still.

I really like this tutorial! Nice job.

BTW the link is broken. It might be the 'this grunge pack' at the end.

Great tutorial.

Thx, both of you. :h:

Good lord, I could kiss you right now. *drools at new brushes*

Hi,

I get to step 15 and have a new image with one layer called background with my cut out pasted onto it.

When I try step 16 I dont get anything selected, well apart from the ants around the border of the image.

Where have I gone wrong? :a:

On the 'Layers' dialogue, right click on the brush layer and select 'Alpha to Selection'. It's got a little red box beside it.

Yeah, but all that does it select the border of the image window not the pasted image inside it?

What you need to do is past the cutout on to the image and without deselecting the pasted section open up the layers dialoge box and press the "new layer" button. Then, "alpha to selection" should work.

wow i HAVE to try this some time :l:

All the images are down :s:

pretty cool

Wow, I didn't know red "X"s were cool :

i have to try this sometime,and yea all i get is bunch of red X's

Kay, Giga got the images back up everyone :w:

Nicely done gigatwo. Thats a cool tutorial. That really help me a lot for making good sigs and avatar. :h:

i cant set the mode to difference... it isnt in the mode for the layers.

nvm i got it.

nice tut,i would have never thought of doing this

I hate to bring back the dead, but I rehosted the images, so the tutorials actually useful again. Unfortunately, I can't recover the images from my other old tutorials.
