Hi all, I'm having issues running out of memory on a current project, in the attached file. Rendering a Flipbook or playing the timeline cause Houdini to eat up about 1GB of RAM per frame, resulting in an OS out of memory error after 48 frames. I've RTFMed and Googled but am not sure how to stop Houdini from hoovering up RAM. Analysis and suggestions will be greatly appreciated! Thanks, John system details: Houdini Apprentice HD 12.0.683 Windows 7 Pro x64 SP1 i7-3930K 64GB RAM Virtua
