transperant textures

quick question: say i have a texture, and say that i want the color magenta to be transperant. how would i do that

with shaders - complex
or with photoshop - easy - just erase the magenta color and save it in a format that works with alpha channel like png. Dont forget to set your part .setTransparency(True)

thanks tree form, its even better than i thought because instead of 1 color mean transparency (2 options), i can put things semi transparent (256 options)

ps: i dont have photoshop, but paint .net did the trick

GIMP!

i do also have the gimp, (and i think i even have movie gimp installed on my old computer) but i like paint .net better i think

i use a commercial program called saint paint because i got a free version from a magazine :wink:
