Hello,

Lately i’ve been trying to use the Celestial Vault Plugin to create a historical environments sky, its going well, however I have encountered one issue, Celestial Vault seems unable to simulate any date before 1 AD. In my case, I need to simulate the year as 500 BC (-499) however Celestial Vault limits itself to 1 AD. Is it possible to simulate premodern dates in celestial vault? If so, how could I do so?

Thankyou in advance,

Willow
