TGA or JPEG ?

[Salombo]

Hello All
I have made a skin pack and changed a few textures from tga to jpeg ... this saves a lot of space. The shader didn't have to be updated.
And the skins work perfectly.

Is there a rule for using tga when jpeg works too ?

Thank you

using psp(mac) and gimp(pc)

I think the shader has to be tga. The real textures can also be jpg.

[Salombo]

Yeah true

A skin I downloaded had a tga shader and a jpeg texture. That's what made me check this out. I reduced the size of the skinpack from 25mb to 9mb by converting large tga files to smaller jpegs. Haven't noticed a loss in detail or quality.

That's why I was wondering if there was some sort of rule for using tgas instead of jpegs. I don't want to end up crashing the server or causing a conflict in any way.

Thank You for answering

tga's can handle alpha channels. used for transparant parts of textures.

If the tga carries an alpha channel - it will be lost in the jpeg.

Well Thank You Guys
That clarifies the dos and donts.

i have seen skin shaders where the file type was changed to .jpg though i see no reason to go through that if the file type lists .tga and it still accepts .jpg .

I do.

Code: Select all

if ( !Q_stricmp( name+len-4, ".tga" ) ) {
	  LoadTGA( name, pic, width, height );            // try tga first
    if (!*pic) {                                    //
		  char altname[MAX_QPATH];                      // try jpg in place of tga 
      strcpy( altname, name );                      
      len = strlen( altname );                  
      altname[len-3] = 'j';
      altname[len-2] = 'p';
      altname[len-1] = 'g';
			LoadJPG( altname, pic, width, height );
		}

not very on topic

i get a 'load tga' error when loading the game when i use custom jpg textures... any ideas how to solve this problem (last time i had to change every jpg tex to tga to fix the problem )?

[bdbodger]

Make sure your .jpg image is a 24 bit rgb color image . What are you useing to make the jpg ?

[k47a]

Thanks! I'm using PS to make them; where can i check that it's 24 bit rgb?

[lizardkid]

they released Q3 codebase? i thought thye just released Q2...

news to Lz2the k-i-d; vader is luke's father .

[bdbodger]

If that means Photo Shop then on the image menu with a graphic loaded click mode and make sure it says rgb color and 8 bits per channel .
