Hy Dale, i'm using 5 node in my HyperVue Network Render; every workstation of my render farm have a VueProfessional Render Cow updated. My vue 4 professional is the 26601 Build. RenderCows crash (sometimes also vue 4 pro... but one problem at time...); usually it crash at the first (sending texture or rendering first frame). I've try also a sample image (Danish spring), adding a camera motion and go to render in network... crash. The crash is randomly, so some times it works... (absolutly randomly...) Thanks. xman
