Ahh, found it... Click the link above and make sure you do one of the steps. If the fixed material (vmt) isn't in a folder that has higher priority than TF or if you've extracted the TF2 Game cache files then the folder you put those in, then it won't work.

well, I tryed that, but, every change was black or red color

These are fixes to the original materals and use the original material names. In order to get them to work, after downloading them via the workshop you have to either give the workshop folder a higher priority than the orginal tf folder or move them (maintaining the file path) to a folder that has a higher priority than the TF folder.

I have subscribed to the workshop item here but i do not notice any changes in game. If you know anything about and are okay to help out let me know. Thanks

When it comes to repairing materials, the first place I look is in to the VMT to see if anything can be changed there to fix the item, then I move in to the VTF if I need to. There arre various fixes that have to be applied, each one has to be experimented with in order to make an item painatble. Try one, if that doesn't do the trick try another. But if you want to materials fixed, you're going to have to learn how to do it, or pray someone does it and uploads it somewhere (like the workshop).

Can you repair the Old Guadalajara? :D

Can you do the same with the xmas spy_jacket?

Paint works my modifying colortint_tmp, which by default is 0, and if colortint_tmp is 0, colortint_base is copied to $color2, otherwise colortint_tmp is copied to $color2, leaving $color at 1 at all times. Setting $color to .5 and $color2 to .5 simply produces the same as $color .25 and $color2 1, so there is 0 reasons to edit ANYTHING other than $colortint_base for things that support it, or $color for things that don't.

This is an alternative option, most ppl will just use the doc ock rokc color script anyway. There they have the option to apply a single colour to all 3 $color attributes using the script. Staying true to the TF2 colour and paint cans is something ppl can do, or just go off the cuff and paint it the way they want this way. If $colortint_base writes to $color2 and tints, by having both attribues available one can paint using $color then use $colortint_base to tone it out... I have no idea how TF2 Paint Cans work, I've never painted an ingame item using one.

The .vmts are set up to directly copy $colortint_base over on $color2, as $colortint_base is not a real .vmt thing. And $color and $color2 simply multiply each other as the colour blending for the texture (though it is weird, 75*13.4=255).

There are 0 reasons it would work better with $colortint_base set to 1 and then editing $color than just editing $colortint_base, unless the .vmt has $color itself edited, in which case the result would still be more faithful to Team Fortress 2 using $colortint_base only.

You can, I find that the colours are truer using the $color rather than the $colortint_base only. Sometimes the $color is set with a value in the VMT which causes an off color if you use just $colortint_base or vice-versa. By setting the $colortint_base to white (transparent) and using the $color to paint the true colour comes through if the colour on the main vtf layer is white.

Okay, seriously, why the [something] do you change $colortint_base to white to paint with $color instead of painting with $colortint_base? Quite honestly, you're the only one to do that at all (maybe except 1 or 2 other people or something).
