A suggestion about textures - agrs700 - 08-20-2010
I suggest using tga textures for models instead of png or just using tga for the textures that require alpha, tga has alpha channel and is used for lots of games. since png uses layers, programs read bad the image data making it look bugged.

Well the main reason that we generally don't use .TGA images is because they are a LOT bigger even when compressed as opposed to basically every other format. If we start using any other format for images it will probably be .DDS if anything. The only reason I haven't done that already is because some games use special variants of the format (the Halo games come to mind) that aren't compatible with normal programs.
I'm not really sure what you're saying with the .PNG transparency either considering that it works completely fine. My avatar uses a .PNG for example and Firefox at least reads it just fine. If you can show me an example of why you think the transparency is "bugged" then I'd have a better idea of what you're trying to gain by using .TGA format.
Besides its not like anything is stopping you from converting the images yourself from .PNG to .TGA once you've downloaded them.

Also i thought about using vtf textures (Valve texture files)
Heres a pic of the bugged texture, maybe png doesnt support partial transparence (50%)

Note: the texture is "bugged" also on the model

Well now I'm almost certain you're doing something wrong. Here is my avatar again with as you can see 50% transparency:

Open it up in Photoshop or something and put a background behind it if you don't believe me. But all I did is just do a quick edit in Paint Shop Pro for you to prove .PNG supports transparency fine. Maybe you're just saving it wrong or something? At the very least you could just keep the texture completely visible and just make the model's material 50% transparent.
And no, we're definitely not using the Valve texture format as the whole point of .PNG images is so that we have a format anyone can use without any real loss of quality. .DDS also sort of fits the bill, but as I said there are a lot of variants of it some more supported than others. Halo was just a quick example, but I KNOW there are other games that use weird variants. And god know if I didn't say to use only .PNGs than people would submit things a bunch of other strange formats that most people can't use.
No there was definitely a reason I kept it simple by telling people to use only .PNG images. Like I said I may change it, but for now its working just fine.

Ye you are right, idk what im doing wrong because i tryed to make the transparence with gimp instead of cs2 and works perfectly, it must be a ps issue or just me

Yeah .png works fine I've only had issues with it like twice and I wasn't sure what was wrong. But yeah VTF's are a pain to convert and even then they lose portions of the transparency upon conversion. The only formats I think would be reasonable would be .png, .dds. .tga all are pretty universal.
