Hi one of the mods on this list called the betweenlands has stopped development but has released a beta unfinished copy of the mod at the back of the comments on the page for 1.5.1. I'm not sure if you wanted to put that instead of coming soon but just wanted to let you know. Thx
hey help - i want find mod for dimension who support portals like vanilla with railroad/mobtransfer and !PIPES! (it will very good), or standalone portal mod for this function for multiworld/other dimension mods
-LightningCraft (Underworld dimension, not so much the Asgardian in 1.8.9 version that I myself have never accessed but it should be possible, the Underworld dimension has been with the mod since though). Mod for 1.7.10 to 1.12.2
Planttech 1 (not 2) adds 2 dimensions, one with shards/coarse dirt islands I think while the other has all the resources you'd consider for the mod plant wise and has lootable structures Mod for 1.8 to 1.10.2, I think the dimensions were more so in the 1.9 or 1.10.2 versions, might have been the last few additions to the mod I think.
-Desertland (was fairly early in development, doesn't exist publicly anymore but I do have the most recent version of the mod, I'll link it on my Google Drive) Mod for 1.12.2, for now here is a video I have on it.
