3dfreelancer Posted April 25, 2020 Share Posted April 25, 2020 (edited) Hi there a very frustrated noob here. I recently moved from another 3d aplication, and Im a newby in Houdini. I did a pyro simulation ( following a tutorial ) and I wanted to do " Save to disk in background " to cache sim ( in geo Pyro Import Node / Dop Import Pyrofields ) but I constantly get message " Cannot perform background render with unsaved changes.Save your file before proceeding." I saved pretty everything I know; project path, sim path ( also tryed ctrl + s) etc. I also checked title in file path so there's no empty space between letters. What am I doing wrong. What else do I need to save, or Im doing it wrong way ? I could not find step by step anywhere explained anything related to " save to disk in background " issue with this message. Could someone pls explain step by step ( if it does not take too much time ) how it should be done so I can check if I did something wrong. I'd very apreciate it and it would help me a lot. Ty very much in advance. Edited April 25, 2020 by 3dfreelancer Quote Link to comment Share on other sites More sharing options...
