Would it be possible for Terrafirmacraft's fresh water to be viewed as vanilla water in railcraft?

TFC died at 1.7. Although there is a TFC2, create a new issue if this is still a problem.

What is the fluid tag for Fresh Water?

I am not certain, but I believe the tag is Material.water
TFC has also ore dictionaried there water buckets as vanilla water buckets.
This is the github for TFC since I do not know what a fluid tag is: https://github.com/Deadrik/TFCraft

I guess is "freshWater" if I look in the right place.

@cabralRodrigo Then it would be "freshwater".

@Vexatos Yeah... My bad :)

Just to let you know, I have made a stopgap solution for TFC water and Railcraft (and other mods) as a separate mod. It just changes vanilla water in the fluid registry to be TFC fresh water.

It's a giant hack, but it works.

Could someone explain why TFC has "freshwater" and whether it also uses "water" and if converting from "freshwater" to "water" is bad?

I'm investigating how to support "freshwater" and its looking like the simplest way is to simply convert any "freshwater" inputs into "water" when filling my machines.

@CovertJaguar I don't think the conversion is a bad thing, since the only use of fresh water is crafting and for drink in TFC

There would be no problem with converting it, as long as this conversion only applies to fresh water and not salt water. Also, would it be possible for RC to recognize TFC barrels as valid liquid storage? Tanks can not currently draw liquid from them.
