How do you go about adding weathering to your textures?


I use several methods, and several more I've not yet used, It would probably take a mini novel If I was to go through them all at once. :wink:

It may be easier If you let me know what one of my textures (or part of) you would like to emulate I could then go through it step by step for you.

Cheers for the reply Brett. After several hours maybe days I have got the effect I want :D

Basically I was wanting to try and simulate the worn out paint look of a certain chopper I have gone back to work on. What I did was follow your technique for the rivets and the underlying black line (makes it look so much better) I then used a grunge brush at very low opacity and set it to burn mode and slapped it around a bit and it gave the impression of worn out paint. Even more so, the rivet, black line and grunge layer were set to overlay, this made it look even better and more blended so I'm happy. Once I'm far in with it I'll post a screeny.

Cheers mate

Ok, here is what I have so far, still tweaking it here and there. If you can guess the bird I'll give you a lollypop :lol:

Now that is looking Really Nice :D

Here's a little tip that I used variations of on the A-26 and B-25 liveries, works best with military type liveries.

In Gimp create a cloud image using the clouds filter.
Remove the white using "colour to alpha"
Save as transparent .png.

Import into Inkscape and use as a "pattern fill" over the new livery.

Here I have duplicated the original .png, coloured it yellow, using the colourise filter, then used as another "pattern fill".

Does this meet your standards Brett? Still needs things adding.

Absolutely :D :D
The Icing on the cake would be access panels and warning labels.

Nice work guys, and thanks for the tip! I'd also like to know how you make those nice exhaust & dirt streaks.. spray can + blur tool + opacity? Cheers!

I don't know how the professionals do the job, but with something like GIMP, using the spraycan set to fade out at various lengths, you can gradually get a fairly convincing exhaust-port-area dirt texture. :)

Cool, I will have to experiment with that.. sometime after I get the models and FDMs sorted out (and someone else makes a cockpit; or I'll just dump the files here and say "have at it") :D

Exhaust stains can be quite easy to do in Inkscape.

Here's how I did the over wing staining on the Twotter:

Create a block of solid colour (left)
Then just add a little transparency and blur (right)

Image

And this is from the A-26 engines which has a bit more shape and colour variation.

Draw a solid shape where you want the staining (top), then apply a gradient fill and blur (bottom).
The red outline shows the drawn shape and the blue line shows the gradient direction with the nodes on the gradient line being colour/transparency changes.

Very nice, thanks! That will definitely add some authenticity to my IAI-1124. It has nasty brake dust streaks because of how low it sits. 8)

Here's one for the Gimp users who want to use Inkscape svg vector file paint kits in Gimp.
You must have both Inkscape and Gimp installed for this.

Open the svg file in Inkscape.
In the layer selection window (Shift+Ctrl+L) hide the layers you do not want to use.
Save the file, using a different name, as an svg file.

open the saved svg file in Gimp, you will get a "Render Scalable Vector Graphics" window where you can set the image size, select 4096x4096 If you want to work with large bitmaps, as svg is a vector format there is no loss of quality in the larger file size in fact it is better.

If you wish to add another layer from the same svg file repeat the process in Inkscape but In Gimp use "Open as Layers" (Ctrl+Alt+O) this will place the new file on a new layer.

All that is left to do is add a new layer and create your masterpiece.

Versions used:
Inkscape 4.8.4
Gimp 2.8.2
