This mod is currently a work in progress compat for Ars Nouveau and Sable/Aeronautics. Adds Sable compat to Ars Nouveau including: - Allowing Starbuncles to path to blocks on sable sublevels - Restoring the player back to the sublevel when entering and exiting a planarium - Allowing source and relays to operate between sublevels and the real world - Warp portals and scrolls will restore players onto the sublevel if bound to it. - Rendering fixes for blocks, particles, and entities.
