boyle Posted December 2, 2016 Share Posted December 2, 2016 I've attached the standard VolumeCompress example. It works fine with the provided volume as mask (in green) but doesnt work when using the camera frustum volume as a mask (in red). What am I missing? cheers B volumecompress.hip Quote Link to comment Share on other sites More sharing options...
dimovfx Posted December 2, 2016 Share Posted December 2, 2016 on volumecompress, when I turn on "Mask Minimum" and turn off "Mask Maximum" it seems to work. the SDF that you create from the torus has negative numbers inside. Quote Link to comment Share on other sites More sharing options...
boyle Posted December 2, 2016 Author Share Posted December 2, 2016 wow, I thought I had tried all the different permutations. big thanks :-) Quote Link to comment Share on other sites More sharing options...

I want to pipe the output of that volumecompress to a cloud noise, but it doesn't seem to work and the errors are not helpful in finding the problem (see attached). Any ideas? volumecompress2.hip Quote Link to comment Share on other sites More sharing options...
dimovfx Posted December 2, 2016 Share Posted December 2, 2016 try to use Convert VDB and convert the volume to VDB to feed the cloudnoise. Quote Link to comment Share on other sites More sharing options...

boyle Posted December 2, 2016 Author Share Posted December 2, 2016 nevermind I found it. Needs to be converted to sdf, then to polygons then to a cloud, and only then can cloud noise be applied. volumecompress_cloudnoise2.hip Quote Link to comment Share on other sites More sharing options...
dimovfx Posted December 2, 2016 Share Posted December 2, 2016 Oh, just looked at why it was working here and noticed that I wrote name="density" in your node "VOLUME_TO_MASK", that way it works fine. Quote Link to comment Share on other sites More sharing options...
