Normal Maps, correct format?

[spinomonkey]

So I've been trying to add planets using Kopernicus and everything appears to be going well. However, there are a few technical questions that remain, if anyone could answer would be super helpful!

What is the correct or preferred format for Normal maps? I've been using .DDS, DXT5 format with so-so results. I tried using DXT5_NM but my planet vanished. I've also tried using a normal full color normal map (normally hued blueish) but that also causes my planet to vanish, so instead I use a gray scale. Also tried a .PNG format as some have suggested- but my planet also vanishes.

DXT5_NM is correct.  Are you using photoshop with the Nvidia dds plugin?

Thanks for the reply.

I sure am, but it hasn't worked in the past. Is there sub-settings I'm missing?

[Galileo]

yes i think so. When you save, do you go into the image options and pick  Normal Map: Object Space?
