Hi there, my friends and I are currently working on a modpack based on gregtech community edition. Today we encountered a big problem:
All use a different oxygen, and there seems to be no way to easily convert between them. I tried unidict, crafttweaker, the industrial foregoing's fluid converter and plain old configs, but nothing works. We are trying to make the modpack as integrated as possible.
The Meaning of Life, the Universe, and Everything.
I'm afraid not all fluids can be unified. Just those from Mekanism are a bit special. Gregtech usually converts many fluids itself if they are similar.
You can write machine recipes so that all devices can use all kinds of oxygen. Or you can do conversion recipes with crafttweaker.
