In the config file of RC there is a part for ic
####################
# refinediron
####################
refinediron {
#
# change to 'disable=true' to prevent Refined Iron from being used in any IC2 recipe. Use in combination with 'useSteel'
#
B:disable=false
#
# change to 'useSteel=true' to enable the use of Steel in any IC2 recipe that requires Refined Iron
#
B:useSteel=false
}
If you use true for both it will replace all refined iron with RC/greg steel.
I was planning to use this on my hardcore server (since steel is more realstic to be used in machines ) but just found it no longer working.
btw does anybody know a mod that can alter/remove IC2 recipes? Tried customstuff but not working
