Looking for a Tutorial on painting grunge layers
polycounter lvl 11
Is there even such a thing?
I don't need an explanation of what it is, I don't need to know that nothing is perfect and everything should have wear and tear (to some degree blah blah). As in a lot of tutorials for texture creation just make the texture and then say "lets scratch it up by overlaying this texture with some scratches". That doesn't teach me much.
Although I'd like to know how people get crisp images using millions of overlays (ok may be not millions). I find that if I'm overlaying photo-sourced images I can't overlay much more than 1 or 2 before things just start to look pixelated and WAY over noised.
I'm looking specifically for something on TECHNIQUE. Paint styles, brushes, types of colours, what works what doesn't etc. To add stuff like mold, dirt, trim, water damage etc. Some tips and tricks to properly overlaying images is key I think. How do you mask off specific areas of an overlay without creating hard edges or obvious spots of cleanliness. Or if my metal texture is already multiple layers and I need to add scratches but adding an overlay of some scratched metal picture just pixelates everything and I lose the detail.
To me it's not good enough to grab some sort of grungy type brush and stamp some dots on my texture and call it dirt. I've seen recently some of the new guys here attempt to do that.
Is this even a reasonable question or desire? I just seem to be at a standstill with some of my texture creation. I know what I want it to look like, but when I try to achieve it it either looks way too noisey or way too fake.

Eric goes over some blend modes and his technique is pretty standard, it might be of some help?

Pretty good library of metal creation tutorials, mostly centered around gun metal.

Great digital painting tutorials, full of tips and tricks. These will help you to hone your painting skills, which I think are VERY important in texture creation. It's always good when you can just paint what you need instead of having to search or magical images that "work the best this time".

Some pretty heavy bathroom reading... Mostly painting theory, but very practical info for games.

I've found that sometimes starting with a max material, rendering that to texture, then painting on it can help get the ball rolling. Over time I've built up a library of Max Materials, concrete, various types of wood, metal, dirt, rocks ect.
Also check out Filter Forge, some really amazing filters, and before you poo-poo the filter route go check it out. Being able to crack other peoples filters open and make your own to suit your needs takes things to a new level. You don't have to worry about learning a foreign script or convoluted code, when you make filters you use a nice user interface.

An ancient HarlequiN tut, but might give you some ideas.

Thanks for the links guys. I've seen some of these, that long Digital Painting wiki-type page is a great resource. And I'm definitely looking for more links on actually painting and texture painting techniques rather than choppery.
Concerning Stefans tutorial. I've tried that to a high degree of unsuccessfulness. I try to make scratch brushes, but for some reason they are too soft and/or wildly out of shape.
The specific scratch brush he uses doesn't transfer well for different sizes as it looses its res. And "make brush" type techniques when selecting stuff I want to make as a brush never seems to hold its resolution. Are there any tips to make good scratch brushes and layers like he does?
You might get some ideas from these brushes.

More brush sets from the same guy.
