Custom Ars Portals
Build Ars Nouveau warp portals in any closed frame shape — round, oval, star, diamond, whatever you can enclose — instead of only rectangles.
Nothing new to craft or learn: build a closed frame out of any Ars Nouveau decorative block, then activate it exactly like always — with a Stabilized Warp Scroll (right-click the frame, or throw the scroll into it). The mod fills the enclosed area with portal blocks in whatever shape you built. Works for both vertical and horizontal (flat) portals.
Break part of the frame and the portal collapses again, just like a normal Ars portal.
Requires Ars Nouveau.
On a server: install this mod (and Ars Nouveau) on both the server and every client — it needs to be on both sides to work correctly.
