How to fade out textures in HUDPaint?
surface.SetDrawColor has no effect unless the alpha value is 0.

Hmm, are you sure the alpha is that sensitive? Perhaps the range is [0,100] or [0,1). Though I was working on a HUD last night and I seemed to get good results with greater-than-zero values, however, I was drawing a primitive shape with a fill.

I presume you are probably drawing a texture, right? If so, check out this link - it explains a problem similar to what you are experiencing: [URL="http://facepunch.com/threads/1000478?p=24926442&viewfull=1#post24926442"]surface.setDrawColor() doesn't affect surface.DrawTexturedRect?[/URL]

Texture probably needs $vertexalpha 1

Thanks. I am currently using surface.DrawTexturedRect to draw one of the default blood textures. Changing the value range does not help. Do I really have to create my own texture with $vertexalpha 1 to be able to change the alpha value?

In the source engine, each texture has two files associated - The [B]vtf[/B] which is basically the actual texture itself, and the [B]vmt[/B] which is a file that [I]describes[/I] the texture, using code. It specifies how that texture is loaded, what pixel shaders are used, etc.

To change the alpha, you will have to edit the [B][URL="https://developer.valvesoftware.com/wiki/Material"]vmt[/URL][/B] file, which is really simple. You can open it in notepad, notepad++, etc. It is just plaintext.

The vmt file will be of the same name as the texture file itself, so finding it should be easy. If you look at the page I linked you to and then take a look at one of the VMT files, I think you will see what I mean. It shouldn't be too difficult.

Good luck!
