I recently purchased [21312-fuck+all+sky.jpg|21312]
I imported the assets, and was ready to start using them. I read the readme and learned how to make the skybox.
“Changing the sky is as simple as making a new material of the ‘skybox cubed’ type, assigning it a sky texture and setting it as your skybox via the scenes’ render settings”
So I made a new Material. Made it a Skybox Cubed. And applying the cubemap. Then I went into render settings, selected my material…and i got this[21313-screen+shot+2014-01-28+at+8.13.21+pm.png|21313]
If this is HD then I don’t want to see what the hell low quality is. This is really pissing me off, seeing as I payed $15 dollars for this add-on. What am I doing wrong?
Thank you in advance! 
The authors addressed this problem in their readme:
Import Settings: Textures are
initially imported at low resolution
to hasten download and import speed,
and also reduce initial disk usage.
To increase the size of the imported
texture raise the resolution settings
on the inspector when you have the sky
textures selected.
You have to select the textures, increase their size, and disable compression.
As I see from your screenshots, a problem in visibility of boundary. Seams shan’t be. That it wasn’t, it is necessary to change one of parameters of import of a texture. Select one of your pictures for skybox. At you to appear the inspector of import (usually on the right). In it there is a “Wrap mode” parameter. By default its “Repeat” value. Change it to “Clamp” value. After click “Apply”. Do the same actions for other textures of skybox. I hope it to you will help.
