Thank you very much IS for all those tutorials like this... after a couple of months break, there's no need to reiventing the forgotten weel again, but just a quick look at things here is enough to bring back some of the lost memory ;]
Though I have some questions for this cube-tut here. I see no screenshot or paragraph about file names and file paths. From what I saw in original setup, cubemaps are stored inside of textures\cubemaps folder (and usually have _e suffix in filename), and the path to the file with cube-map for certain NiTriShape is stored at 5th place on its BSShaderTextureSet list. I can only presume that cubemaps don't need _e suffix in filenames and don't need to be placed inside of that cubemaps folder - is that correct? But the path to cube map in BSShaderTextureSet is mandatory I think... had no time to test this -?-
