Mods introducing new content into the game.
Furnaces, assembling machines, production chains.
circuit, circuit2, and neural-circuit look like my advanced computer chip, advanced computer processing chip and computer chip.
Yes, I think you should not use the sprites from other mods unless they share the same functionalities. At least give them new colors.
And, although Yuoki seems don't mind that, I think it is better to ask him for permission when you want to use his assets for another mod. https://forums.factorio.com/viewtopic.php?f=15&t=502&p=33103
All circuits have been replaced with home made graphics. The bioreactor actually came from the BioIndustries mod.
you missed circuit2 that item is in my mod Andrew's Library as advanced computer processing chip.
Ah, that one is not used in game. The file is deleted in my version now.
