This is a very simple tutorial on how to create a grunged texture in GIMP. For this we’ll be using the fog renderer, bump mapping and some layer effects.
Let’s get started.
Step 1 – Start with a new, 800x600px white background image.
Step 1 - 800x600 px with white background
Step 2 – Let’s create some fog
Go to GIMP’s menu Filters -> Render -> Clouds and select Fog.
Set the fog color to #8c6929, turbulence to 1.1 and opacity to 100 as in the next image.
Fog parameters
You will notice in the layers dialog, that a new layer called Clouds has been created.
You should have an image similar to this one.
Step 2 - Intermediary result
Now repeat this step one more time but adjust the turbulence to 2.5, then duplicate this layer.
We have now an intermediary result with 3 fog layers (Cloud, Cloud #1 and Cloud #2) as follows:
Step 2 - Itermediary result with all fog layers
Step 3 – Grungify the layers
Set the layer mode for Cloud #1 to Multiply and for Cloud #2 to Grain Merge.
Step 4 – Let’s add some scratches
Create a new transparent layer and named Scratches (or whatever).
With the pencil tool and pixel brush draw some white random lines and curves.
I did it like this:
Step 4 - Scratches to be
Now go to GIMP menu Filters -> Blur and select Gaussian Blur. Set the blur radius to 4 or 5.
Go again to GIMP menu Filters -> Map and select Bump Map. Set the parameters as in the next picture. Set the bump map to Scratches layer.
Step 4 - Bump map settings
After clicking OK set the layer mode to grain merge.
Step 5 – For greater effect let’s add a vignette effect.
Create a new layer an name it Vignette. With the ellipse select tool make an elliptical selection like this.
Step 5 - Elliptical selection
Invert the selection (CTRL + I) and from the GIMP menu Select -> Feather set the feather selection by 125 px.
Now fill the selection with black and set the layer opacity to 55%.
Grunged background - Final Image
That’s it. Hope you liked it.

awsome tutorial. in the gimp file there is also the text as in the post’s featured image. i think it’s a nice effect. how can i make the same and what font did you used?
The font is ‘Dirty Headline’ and you can get it from dafont.com.
The effect is obtained the same way as for scratches layer.
Thanks for visit.
It will be really kind of you if you suggest me a website from where to download the fog cloud effect. Because i apparently don’t have it.
Thank you
You can get the source code of the python-fu script here: http://gimp.sourcearchive.com/documentation/2.6.0/foggify_8py-source.html.
You need to copy the code in a file named foggify.py and put it in your gimp plugin folder. Also you will need to have python installed. If you are on windows check this tutorial on how to install python in windows at gimpusers.com.
Also, here is a description of the plugin: http://docs.gimp.org/en/python-fu-foggify.html
Amazing tutorial…the problem though is Under Filter–>Render, there is difference clouds and no FOG… where can I get the Fog Filter?
