How about being able to use liquids as a nearby requirement or even as the base under the soil. Just a thought.

Ok, well I have tried a few different liquids and was unable to get them to work. I thought maybe not feature. Will do a few more tests and see if I can get it to work. Sorry to have bothered

I am sorry, I got it to work. I was using minetweaker to get the liquid name and forgot to include the modid. I apologize

Glad that you were able to figure it out.

This should already be possible as liquids are blocks.
