How can I make a resource transparent?

[C0LDSt33L]

I would like to make one colour (white) on my custom resource transparent while leaving the rest of it opaque. Could anyone point me in the right direction, please?

Save you image as .tga
Open it with texview and save as .paa

Once you've made a resource and converted it to .paa using texview how do you go about getting your resource to appear in the drop down 'resources' box in the editor so you can use it in the game? Is there something that you have to put into the dexscription.ext file?


Thanks
