Rebar doesn't seem to be owned by a mod. If i use a mod based filtering system it shows up as UNKNOWN. I noticed this problem in particular with logistics pipes.

This is how EnderIO does it: https://github.com/CrazyPants/EnderIO/blob/ccd589214ec1a7b7373ce49ae3a99203c0322c8f/src/main/java/crazypants/enderio/conduit/item/filter/ModItemFilter.java#L62

As far as I can tell that should work. Rebar is registered to the game registry like everything else.

This is fixed in 9.5.0.0
b0d131d

Oh, heh.

What version are you running?

Oops

9.4.0.0 sorry i didn't even think to put that on there.

just checked with ender io mod filter and their item conduits. it doesn't detect the mod as anything at with rebar. other railcraft items are detected tho. i don't know of any other mod filtering mods to test it with but it doesn't work with logistics pipes or ender io.

with some further testing locomotives, track relayer cart, electric meter, ,undercutter cart, remover cart and some other items also do not get detected. i don't know if this is related but @mod.Railcraft in nei omits these same items. it shows the others that are detected tho.

I can't see any differences registration wise between the Rebar and say Plates or Gears.

Well it appears I need to know more about how these mods are getting this information (or not getting it in this case).
