Definitely back, for the time being. Photosynthesis Absorbs Carbon is actually my old fix/tweak mod. After I was invited to the project here, I merged them into this mod. Photosynthesis Absorbs Carbon is going to be retooled to configure a lot more that's probably outside the scope here, like recipe times, outputs, sugar solution power density, etc. Not done yet, but it's ongoing.
Matt's Biotech Changes is a must-have of mine. I love the texture changes. Matt hasn't been active in modding anytime recently it seems, but the license for using the textures seems to allow repackaging them here without issue. I'll see about adding them as a built-in configurable texture option in the future.
Needless to say, as long as I have the time to, I plan on keeping this mod going in the absence of Slopppy. It's an old favorite of mine.
