I’m making a level of sorts for my game (Which is being made using XNA, by the way, not the Blender Game Engine, if it makes a difference), and I’m wanting to put a texture as a sky, however, I’m having problems with doing so.
At first, nothing comes up, untill I play about with the “Paper Sky”, “Blend Sky” and “Real Sky” checkboxes, then I eventually get a negative/black & white version of the image.
I remember I once got it working ages ago by pure luck, but I haven’t been able to do it again.
also check the normals. are you using a cube, a plane, or what?
the normals of cubes and planes must be facing inside / down, respectively.
if you wan to check it, go in edit mode, press A to select all, and in the tools (left panel) find where it says “normals”, press “recalculate” and then “flip directions” (or inverse, or something like that, i don’t remember exaclty now).
