when I say I followed the tut in video I did not fully mean I was attempting to use spacescape to generate and bring in my images, I was just using the steps in the video to align and set up my images not generated with spacescape and how to setup a skydome in unreal4. so my problem is not exporting out of spacescape but bringing in a cubemap in DDS to unreal4 since it seems something is wrong since it shows ok in amd but on importing into unreal4 the skybox loads ok only its flipped on side for how its showing it.
The cubemap is also properly showing on the AMD marble and skybox preview.
