Working away on a model, smooth it to edit it a bit then i go to get rid of the node or turn itterations to 0 and the inputs are gone. Mabey i erased my history but if i smooth again i dont get another node nothing no inputs show up in the scene. opened another scene and inputs are there. Is there something i can reset to show inputs ect...

P.S. constructionHistory - tgl on; is the fix. No idea what happened to begin with however.
