UDK/UDN image importing

2 h lost in research... but finally some knowledge get in.
So what you should be aware off when you are importing textures in UDN.

1) Texture formats : .tga, .png and the others from the scroll bar / UDN does not support .jpg! /

2) You should use RGB color scheme

3) For non transp textures 24 bits .tga is good. For transp 32bit .png or .tga / for main menus .png is best coz of the size reducing /

4) And the issue I struggle !!! Your textures must be " Power of 2 " examples :
2, 4, 8 ,16, 32, 64, 128, 256, 512, 1024, 2048, 4096  / you also can combine 512x256, 1024 x 512 etc /

And here is the lame thing. If lets say you have " Play " button which is 120x80 pixels ... you should use 128x128  / you will fill up 120x80 / and the rest must be transparent. It's not a big deal ... but it's a little pain in the ass to figure it out.

>.<

p.s Maybe there are some other stuffs to be aware off but for now this is from me. [ Cheers ]
