So I've been trying to work on my custom skybox for the artpass map but I just can't get it to look good in the game. Somehow, as soon as VTF edit opens up a smooth-looking PNG file it goes completely bonkers and makes a mess out of my gradients. I've tried changing around most of the normal settings, trying to get the "advanced" gaussian blur to smooth the errors out but to no effect, the changes don't seem to matter at all. This is how the image looks if I open it in Photoshop (left) and VTF Edit (right) And these are my settings, basically default everything. Any suggestions at all? I've tried getting the plugin for Photoshop to work but not successfully so that's not really an option either.
