UV mapped skycube

Kinda simple request:
since the standard 3DGS skycube can't be rotatet/transformed at runtime, it would be superb if someone here who is handy in modelling software could make a simple 6 sided cube, which is UV-mapped in a way that we could simply assign our existing skycube images as a skin and go from there.
basically the 6 sides placed seamlessly next to each other on the texture.
This should be a small but very useful asset for all 3DGS users...

you can find one in my little MapBuilder package. and maybe in Mystimoods too.

Oh my god... you have no idea how happy I am right now!! Thank you sivan!!!! :))

not at all. I remember now, the mystimoods one is wrongly mapped, my one is the correct.

Are there some shader tricks or configuration tweaks I could utilize to get the model to behave more like a real skycube? The edges are still too visible for my taste.
