https://forums.autodesk.com/t5/maya-dynamics-forum/bifrost-stopped-working/m-p/5732620#M7329 <P>Thanks for all the suggestions and responses. I learned a ton of new options in the process.</P><P>&nbsp;</P><P>Ironically none of these options worked for me. After banging my head against the wall quite a bit a tried a lot of things. What got this to finally work is selecting the "Flush Scratch Cache" command from the Bifrost menu. After that bifrost start the simulation (with my file as is - even without changing the start frame or any other settings). This is very strange because this seems to be the solution for every new scene I create. I don't know what Bifrost doesn't like before I issue the flush scratch cache but that seems to be the trick in my case.</P> Tue, 21 Jul 2015 23:22:28 GMT techvd 2015-07-21T23:22:28Z
