vesaw55345 Posted February 12, 2022 Share Posted February 12, 2022 I am having problems getting advect volume growth to work and I believe (at least in Houdini 19) the Curvature analysis in vdb analysis does not work as presented in this older Entagma tutorial. According to the comments on YouTube other people have the same problem with newer versions of Houdini. There's no answer on YouTube which is why I'm posting here. Basically multiplying with the curvature doesn't do anything.. Any clues on why? advection_recovered.hipnc Quote Link to comment Share on other sites More sharing options...
flcc Posted February 13, 2022 Share Posted February 13, 2022 It's a typo problem. In the VDBAnalysis you create a "Grad" Volume. But in the volumeVOP you bind import and export "grad". In addition the Ramp on the VolumeVOP is 0 Flat. advection_recovered fix.hipnc Quote Link to comment Share on other sites More sharing options...
