Factorio Forums

While working on fixing and improving the Factoriopedia for my own mod, I begun to notice something odd going on with some of the entries: Items would merge with their recipes if the recipe had the same name as them, even with byproducts, but fluids seemed not to

Some examples of this are with this one recipe in my mod, where an item merged with its recipe after changing the recipe name, which seems to be the intended behaviour: however, a similar fluid recipe would not merge with its actual fluid and considered the intended recipe for obtaining that fluid an "Alternative recipe": despite the recipe and main_product being exact same as the fluid: this also occurs with another fluid that only has one way of being produced, and is only used in one recipe to create another fluid: (you get the point by now ), i was advised to make a test mod to see if it was specifically fluids that wouldnt merge with their existing recipes, even if an item would - as you can see here, the test item merged with the item: however, when i change the test item into a fluid, this happens: I have also included the test mod used in this post, just so you can test it out if you so wish :]

You are describing intended behavior of fluids. If you check the game without third-party mods, you will see that all fluids are in the separate tab and not merged with recipes. I currently don't see any way I could help you with your problem.

The following vanillaSA fluids are merged with their recipes: Lubricant, Sulfuric acid, Thruster fuel, Thruster oxidizer, Molten iron, Molten copper, Holmium solution, Electrolyte. As noted by OP, the required condition is that the fluid name matches the recipe name.

The inconstistency is how this merging happens regarding recipes with more than one product.
In vanillaSA I did not find any merged recipe+item with multiple products. The closest are Iron/copper bacteria, hovewer, they are still separate. Designating iron-bacteria as main_product does merge them. The similar does not happen with fluids (the order of products is also not preserved, the fluid is moved back; no idea if it's relevant and/or intended) - fluid and recipe are still separate.

yeah i worded this terribly, thats on my part - the issue is that fluid recipes with *byproducts* do not merge with their recipe, despite items doing that, which i presume is not intended behaviour
