Title: Custom textures: Alpha Channels help.
Post by: bLiNdThInG on September 05, 2010, 10:13:21 AM

hi all, need some help with textures, specifically transparency.

I searched the forum and found this http://dplogin.com/forums/index.php?topic=39.0 which was very useful, so i did exactly what was said but the part of the texture still isnt transparent. as shown below.

(ps. yes the texture is a jet but it'll make sense when i release the map.)

I'm using photoshop CS4, saving in .tga and 32bit.

In bsp ive set 'requiredfields' 'script/skyhigh.txt'

and the contents of the script are

textures/blindthing/jetfighter
{
     {
           map textures/blindthing/jetfighter.tga
           alphamask
     }
}

some screenies of the image open in photoshop aswell -->>

i still cant see where im going wrong, its probably something really simple, but i hope someone can help me thanks.  :)

Doesn't Photoshop show a chequered background to indicate transparency? :S

In BSP you need to set both the Trans33 and Trans66 flags for the texture.

On a side note, you should make all of your textures powers of 2 (64x64, 256x256, etc) otherwise they will be scaled in the engine and not look as good.
