⬇ Download on ModrinthPLEASE READ BEFORE DOWNLOADING
This is a continuation and port of Valkyrien Portals from Forge 1.20.1
If you're like me, you found yourself on the NeoForge side of 1.21.1 with so many awesome mods. If you're also like me, you had Immersive Portals and also found the new player port of Valkyrien Skies... But crap. On first launch with both mods --- crash report ... NOOOO, they're not compatible..
Until Now...
This compat mod brings almost full compatability between Immersive Portals and Valkyrien Skies allowing the best of both player transport mods.. :-)
So, with that being said....
