catchyid Posted April 4, 2017 Share Posted April 4, 2017 (edited) [Still one questioned unanswered, plz help me answer it ] Hi, I am rendering pyro simulation in an external renderer that reads VDB, hence I export pyro as VDB (using convert VDB node). I have the following two question: -Is there a way where I can see the value ranges of "Heat" calculated? Meaning, min heat is 5.0 and max heat is 20.0? I need to know the max/min ranges in order to tune the rendering parameters... -The external renderer reads "Temperature" to render fire, however Houdini uses "Heat" instead, so my question: how to rename "Heat" to "Temperature"? [SOLUTION: just add primitive wrangler and type s@name = "new_name"] Thanks, Edited April 4, 2017 by catchyid Quote Link to comment Share on other sites More sharing options...
GeneralLethal Posted April 4, 2017 Share Posted April 4, 2017 (edited) One possibility is use volumemin() and volumemax() expression functions before converting to vdb. Edited April 4, 2017 by GeneralLethal 1 Quote Link to comment Share on other sites More sharing options...
