Immersive Ascension
Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
An addon for Immersive Engineering that adds stairs and stonecutting recipes for anything that already has a slab. Also adds 2 new Uranium Block variants…
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This addon for Immersive Engineering adds stairs for anything that already has a slab.
- Blocks of metal
- Block of Coal Coke
- Sheetmetal
- Colored Sheetmetal
- Coke Brick, Blast Brick, Kiln Brick, and Reinforced Blast Brick
- Insulating Glass
This mod also adds
- Stairs and Slabs for Slag Glass
- 2 variants of the Uranium Block, both with Slabs and Stairs
- Stonecutting recipes for all of it, plus the Slabs from base Immersive Engineering
- and the Coal Coke Slab can now be used as fuel in a furnace, as can the new Stairs
Special thanks to my brother, who continues to help me with all of my coding related questions.
