[SOLVED] Need help - HPS/Skybox trouble

[Ravi]

Guys,I need some help here!! Issue is the same,that skybox is not showing as the way I have made it and is completely white on the level editor.
I have been trying to make my custom story with my own custom skybox.
I have followed several posts on the net and with tiring efforts was able to make the dds file.
However,on the test run of the custom skybox(star lit sky,black in colour),
it loaded partially on my level editor(showing half black and half white).

Now after few attempts and tweaks it's now completly white.
I have done the following tweaks:

1. updated .hps file of my map and added the following lines.
SetSkyBoxTexture("skybox24.dds");
SetSkyBoxActive(true);

2. deleted the map cache file.

3. added the following in resources.cfg file;
<Directory Path="/custom_stories" AddSubDirs="true" />

4. placed my sky box file in "custom_stories\story folder\textures"

I don't know where i'm going wrong.
Help will be much appreciated.
