I just got my first smelter into orbit, thinking that I could recycle the crew launcher and return to the planet via capsule, but the smelters only return 1% of the Scrap as Metal. The thermometer I placed on the smelter hovers around 300 degrees Kelvin, but the info panel on the smelter shows efficiency climbing steadily. Is there a way for me to change the efficiency to a fixed value while the temperature systems gets fine-tuned?
I am using ExtraPlanetaryLaunchpads version 6.3.2 with KerbalSpaceProgram version 1.5.1.2335
I am also running Tweakscale, CivillianPopulation, KerbalInventorySystem, KerbalAttachmentSystem and their supporting mods as well, but I have the same problem after un-installing and re-installing just ELP, MM, KIS.
take care and have fun!
