Taking a ghusal while nude

Assalamu Alaikum,
Thank you for answering my previous question regarding taking nude bath in Islam. I have another doubt regarding the same,
1) can a person who is in the state of janabah take bath nudely? Why i’m asking is, while performing Ghusl, one needs to do Ablution as a part of sunnah.
2) So if a man does ablution nudely, will his ablution be accepted and his ghusl is fulfilled?
