Are you playing FTB Unleashed? If you are, you can try out the Portalgun mod's turrets. I used them for my bat claws farm using MFR's Auto-spawner to spawn bats, the turrets to kill them and conveyor belts to funnel them into an item collector block which feeds it into my item tesseract.I've made a similar setup except I'm using an mfr auto spawner to spawn tons of butterflies. Is there any good way to auto kill all of them and collect the pollen? Mffs seems to just kill and not drop anything, although I no next to nothing about that mod so I may be doing something wrong. Mfr grinders don't work. Anything I else I could try?
You might wanna test out the turrets to see if they will shoot at the butterflies or not.
