Skyboxes not working. Game bug?

[Mudbill]

If you have a .map_cache file with your map, delete that and see if that changes anything.

If not, make sure that wherever your skybox is located if it is not included in any of Amnesia's folders has been added to the resources.cfg file.

Otherwise, I got nothing :/

Thanks for the suggestions, although it still seems to be the same :\

I had actually forgotten to add the custom_stories directory to the resources.cfg after a reinstallation I did some time ago. I thought perhaps this would help, but it didn't. I tried copying the skybox to the main textures/envmaps location, yet same result. I tried manually typing the path to the file in the level settings in the editor, but again, it appears in the editor but not in the game.

I do delete the .map_cache files quite often too. Been working with HPL2 for 1.5 years now, so I'm quite custom to most of it, yet this skybox I do not know what to do about.
