How to do alphas in GIMP?

[Birdflight]

i've recently started to re-texture clothing, but i have trouble with one section. i've followed the tutorial on tsr, but it doesnt cover doing alphas on gimp. i'm really not sure what to do. i've managed to create the white image on black, but when i paste it onto the alpha it pastes it onto the entire multiplier and mucks it up. i've read somewhere that you can create new alphas, but i cant seem to on gimp. It also says something about saving it as an alpha and then importing it? :wtf: any help would be welcome! :P

ps: hope this is in the right section :faceslap:

yeah, i've looked through that before, but i'm no closer to being able to create one! i know it automatically generates alphas, but they are just a black filled in version of my design. i was led to believe that they should be white on black? thanks!

well, it displays how to add a alpha layer/channel.
Texturing the alha layer/channel you have to do yourself. :)
With only black and white, white are the parts you want to be visible while the rest is black.

thats my exact problem- the alpha is just a black image on a transparent canvas, and when i paste the white on black image onto it, it changes the entire multiplier- is it meant to do that? the tutorial also says to save and import it onto tsr workshop as a alpha! feeling really thick now >.<

If you're willing to download one more free program you could try paint.net and the alpha space plugin for it. It makes your image into an alpha very easily and it takes two seconds to figure out how to do it. I'll post the links in case you're interested. Before I got paint.net alphas were a constant frustration...now I don't even think about them...I just open them in paint.net and zap out an alpha :)

thanks! it sounds so much easier! do you know how to import them into the workshop though- do they just go in with the multiplier? :bunny:

why not import as png if DDs confuses you?

In your texture editor you need to find your channel editor first.
Look under tools or options.
A dds/png is divided into 4 channels(rgb) or 5(rgba)
If you want to color the alpha channel you first need to be able to select it.
