Skybox Texture Compression Issue

PogoP

Hey guys,

Just having an issue with my skybox and compression settings in UDK. I've done a quick Polycount search and found one thread but I couldn't fix my problem.

Basically, this is my problem:



As you can see, it looks better uncompressed. I don't mind compressing the skybox, but not to this level. It just looks really pixelated. Does anybody know any tips or tricks to be able to get around compression issues in UDK?

I am currently using 'TEXTUREGROUP_Skybox' and LODBias of -2 (a tip I found in the other thread), but it is still looking very pixelated.

Cheers guys!

I just checked that screenshot on my laptop and you can barely see the difference! Ooops. There is a noticeable difference in-game though, if anyone has any tips I'm more than willing to hear them!

This is the terrible nature of DXT compression, it hates dark colors and has a hard time with subtle color shifts. My suggestion is to make your skybox have highcontrast in photoshop and then de-contrast it in the material using a pow with an exponent of <1

Cheers Jordan, I'll start that now. What do you mean by a 'pow'?

Edit - Nevermind, I presume you mean power.
