Pavel K Posted May 23, 2020 Share Posted May 23, 2020 I simulated smoke at 0.01 and then tried to upres to 0.008 but it doesn't work. Gasupres node just gives me an error "No volume or VDB primitive found in reference geometry". What am i doing wrong? smoke_upres.hipnc Quote Link to comment Share on other sites More sharing options...
Pavel K Posted May 23, 2020 Author Share Posted May 23, 2020 Ok, i think I've figured it out. You have to do it through dopimport node and use the exact same fields for original low res as well as upres. Quote Link to comment Share on other sites More sharing options...
Atom Posted May 23, 2020 Share Posted May 23, 2020 A few of things. On the gasupres node make sure you set the Fluid Type to Smoke, not Pyro. Also, you have to drop down an attribute wrangle between the lores and the upres node to create a detail attribute named @timescale. When this attribute is missing the time scale defaults to 0, which is no motion. Set it to 1.0 to test, but try other values to speed up or slow down the upres. On the output of the lores dopnet, you need to add temperature and vel fields which get forwarded to the upres network. Without those, the upres simulation won't work. ap_smoke_upres.hiplc 1 Quote Link to comment Share on other sites More sharing options...
