I can not find zink ore. Where to find her? I also have no steam engines. this is a bug? 1.12.2

I have also been unable to locate Zinc.

Zinc can be found around Y30 as shown in the config, you will just have to keep looking. Steam Engines have not been ported

After pulling up my world in MCEdit it appears that it is just not loading in older chunks. I enabled retrogen for the zinc, however the Railcraft Retrogen mod on Curseforge is not compatible with 1.12.2.

Oh, thanks!

I faced this problem.

Fixed by disabling IC2 Macerator recipes for Ore Dusts in railcraft.cfg config.

Find:

            # 
            # change to 'ores=false' to disable the IC2 Macerator recipes for Ore Dusts
            # 
            B:ores=true

And change B:ores to false value:

            # 
            # change to 'ores=false' to disable the IC2 Macerator recipes for Ore Dusts
            # 
            B:ores=false

Same issue

After tweaking around a lot I managed to generate zinc but with an very rare amount (0.01% at y30-y40)

Also the world module overrides every world gen (especially CofH World (Thermal Expansion) so you can't disable / enable and tweak ores with cofhWorld or similar mods)

It would be nice, if we could use cofhWorld to manage railcraft ores

Edit

Removing every ore gen file from /railcraft/ores/ let's cofhWorld control the worlgen but zinc as
"block": "railcraft:ore_metal",
"metadata": 5,
Generates Copper with a green texture and an invalid item texture

Edit:
Fixed it with CofhWorld:
Using the following code structure makes it able to handle CofhWorld to manage any railcraft ore:

....
"block": { "name": "railcraft:ore_metal", "metadata": 5 },
....

Note that metadata is actually deprecated so you may want to use properties:

....
"block":  {
    "name": "railcraft:ore_metal",
    "properties": {
        "variant": "zinc"
        }
    },
....

The above did not fix the issue for me. Still cannot find Zinc anywhere. Enabled retrogen for Zinc too so i could try and spawn it any way possible.

i do not have this problem with railcraft-12.0.0 in FTB-Revelations

Mined a 265 x 265 block down to bedrock. No a single block of Zinc! Not on y=30, not anywhere.

--edit: expanded that to 400 x 265. Still nothing.

--edit: my hole is now 400 x 400. Still nothing. I have digital miners also in different biomes, and none of them find Zinc. What is the distribution of Zinc supposed to be? Maybe I could just cheat and give myself x blocks of zinc ore for every 10000 others I mine.

Zinc generates in Lead Mines.
