ah-fx Posted August 16, 2017 Share Posted August 16, 2017 This seems like a simple one, but I must be missing something. I would like to create a vdb from a camera with fog volume values inside the frustum area. When I choose 'From Camera' the vdb sop node shows me a frustum guide with appropriate dimensions but it always gives me 0 voxels. This is Houdini 16.0.633 Quote Link to comment Share on other sites More sharing options...
afx Posted August 17, 2017 Share Posted August 17, 2017 Yeap I believe this has been a bug since the 16 release. Unless we are both doing something wrong... My workaround was to either create geometry which represented my frustrum and then vdbfrompolygon. Or you can try the volume sop and then converting to vdb. Good luck!

ah-fx Posted August 17, 2017 Author Share Posted August 17, 2017 well I feel better that I am not missing something obvious. Thanks! Quote Link to comment Share on other sites More sharing options...
crozer Posted April 14, 2018 Share Posted April 14, 2018 hey, it is actually working (16.0.621 in my case). perhaps you have forgotten to activate the vdb region? (place a vdbactivate after the vdb sop that is getting the cam frustum) Quote Link to comment Share on other sites More sharing options...
