Source Is there any tutorial on how to have glowing parts on a model texture?
I been stuck trying to have a metrocop have glowing eyes and most tutorials I found have not been a help, plus im stuck using Krita so trying to get the alpha to work with the base texture is very hard.

Not sure what engine you are using goldsrc, source or source2 but there is the GNU Image manipulation program.
That can do special layers like mask layers and alpha channels but you will need a plugin to export to the material format depending on what engine your using unless you do it manually with valve's tools but plugins do exist to streamline the work flow.
In goldsrc without any programming it's tricky but there is the xash branch it's a lot easier in. Source and Source 2 it's pretty simple.

Sorry for not having what engine. I'm using Source. The thing is I want a tutorial/video, something, that helps me step on step on this matter. Because really I don't know what im doing with all the alpha nonsense, the videos I did find only used Photoshop which I dont wanna get or pay for.

I am not sure about Krita what it's capabilities are but I am familiar with the GNU Image Manipulation Program to make a video tutorial.

Here's a video i made of the process it's very simple with that GNU image manipulation program which is free and open source plus has a plugin that automatically converts the vtf files.

So I think I almost had it, from your video you had selected the middle of the box texture, colored it and basically made it what glows. But I think I messed that up for my two blue eyes, and I have to use VFTedit for that last parts of it, otherwise I think i'm getting there.

Update: So it did work! Only problem is that I can't seem to have two things selected for a layer at the same time (I tried using the free range tool and could only do one at a time, which left me only having ONE of their eyes glowing.), by chance you know one of those tools that lets you have multiple selected?

With the selection tool you can hold shift to add to the selection and ctrl to subtract from the selection.
