Otherwise they will make huge lag when loading, and uses memory not effectively.
For me it loads instantly. Also, a 4096*2048 RGB texture only takes up 24 MB of memory if I'm not mistaken. A texture like this might be an issue for people with very low-spec systems, but for most users it would not be a problem.
I will make a cubemap version if there is demand for it.
