the best way to make my own decals??

Id like to start creating my own decals. Can someone tell me what the rules are on it? I have gimp I just dont know exactly what the texture needs to be. For opacity and what not.

Thanks everyone!

3 Steps

-Add Alpha Channel in Gimp http://vendiadev.wordpress.com/2010/11/30/hello-world/

-create texture as you like, with alpha / checkerbox wherever you want clear to be

-in ue4, make your material domain “Deferred Decal” and use Transluscent

#Additional Notes:

-your texture must have power of 2 dimensions, like 32x32 or 32x64 or 128x256

-hold down the T key in material editor and left click to make Texture Sample and plugin your imported texture

#Enjoy!

Perfect thank you greatly! !! ; )
